Description
The S Series AC-DC and DC-DC converters represents a broad
and flexible range of power supplies for use in advanced
electronic systems. Features include high efficiency, high
reliability, low output voltage noise and excellent dynamic
response to load/line changes. LS models can be powered by
DC or AC with a wide-input frequency range (without PFC).
The converter inputs are protected against surges and
transients. An input over- and undervoltage lockout circuitry
disables the outputs if the input voltage is outside of the
specified range. Certain types include an inrush current limiter
preventing circuit breakers and fuses from tripping at switch-on.
All outputs are open- and short-circuit proof and are protected
against overvoltages by means of built-in suppressor diodes.
The outputs can be inhibited by a logic signal applied to pin 18
(i). If the inhibit function is not used, pin 18 must be connected
with pin 14 to enable the outputs.
LED indicators display the status of the converter and allow for
visual monitoring of the system at any time.
Full input-to-output, input-to-case, output-to-case and output-to-
output isolation is provided. The converters are designed and
built according to the international safety standards IEC/EN
60950 and EN50155. They have been approved by the safety
agencies TÜV and UL (for USA and Canada).
The case design allows operation at nominal load up to 71 °C in a
free-air ambient temperature. If forced cooling is provided, the
ambient temperature may exceed 71 °C, but the case temperature
must remain below 95 °C under all conditions.
A temperature sensor generates an inhibit signal, which disables
the outputs if the case temperature Tcexceeds the limit. The
outputs are automatically re-enabled when the temperature drops
below the limit.
Various options are available to adapt the converters to individual
applications.
The converters may either be plugged into a 19" rack system
according to IEC 60297-3, or be chassis mounted. They are ideally
suited for Railway applications.
Features
Important: For applications requiring compliance with IEC/EN
61000-3-2 (harmonic distortion), please use our LS4000 and LS5000
Series with incorporated power factor correction (PFC).

100 Watt AC-DC and DC-DC Converters
APR 26, 2006 revised to SEP 25, 2006 Page 4 of 33 www.power-one.com
Functional Description
The input voltage is fed via an input fuse, an input filter, a bridge
rectifier (LS), and an inrush current limiter to the input capacitor.
This capacitor sources a single transistor forward converter.
Each output is powered by a separate secondary winding of the
main transformer. The resultant voltages are rectified and their
ripple smoothed by a power choke and output filter. The control
logic senses the main output voltage Vo1 and generates, with
respect to the maximum admissible output currents, the control
signal for the primary switching transistor.
The second output of double-output models is controlled by the
main output but has independent current limiting. If the main output
is driven into current limitation, the second output volt age will fall as
well and vice versa.

switch-on/off cycles increase the inrush current peak value.
3For 1 s max.
4AC operating frequency range is 47 to 440 Hz (440 Hz for 115 V mains). For frequencies ≥ 63 Hz refer to Safety and Installation Instructions.
Input Transient Protection
A suppressor diode and/or a VDR (depending on input voltage
range) together with the input fuse and a symmetrical input filter
form an effective protection against high input transient volt ages
which typically occur in most installations, but especially in
battery-driven mobile applications.
Nominal battery voltages in use are: 12, 24, 36, 48, 60, 72, 110,
and 220 V. In most cases each nominal value is specified in a
tolerance of –30% to 25%.
In certain applications, surges according to RIA 12 are
specified in addition to those defined in IEC 60571-1. The
power supply must not switch off during these surges and
since their energy can practically not be absorbed an
extremely wide input range is required. The ES input range
for 110 V batteries has been designed and tested to meet
this requirement.

Input Fuse
Afuse mounted inside the converter protects the module against
severe defects. This fuse may not fully protect the module when
the input voltage exceeds 200 VDC! In applications where the
converters operate at source voltages above 200 VDC an
external fuse or a circuit breaker at system level should be
installed!
The inrush current peak value (initial switch-on cycle) can be
determined by following calculation:

Reverse Polarity
The converters (except LS) are not protected against reverse
polarity at the input, but in general, only the input fuse will trip. LS
models are fully protected due to the built-in bridge rectifier.

Input Under-/Overvoltage Lockout
If the input voltage remains below approx. 0.8 Vi min or exceeds
approx. 1.1 Vi max, an internally generated inhibit signal disables
the output(s). When checking this function the absolute maximum
input voltage rating Vi abs should be considered! Between Vi min
and the undervoltage lockout level the output voltage may be
below the value defined in table: Electrical Output Data.

For AS, BS, and FS as well as for application-related values
use the formula given in

to get realistic results.
Inrush Current
The CS, DS, ES, and LS models (not -9, not option E)
incorporate an NTC resistor in the input circuitry, which at initial
turn-on reduces the peak inrush current value by a factor of 5 to
10. Subsequent switch-on cycles within short periods increase
the inrush current due to the hotter NTC resistor.

Thermal Considerations
If a converter is located in free, quasi-stationary air (convection
cooling) at the indicated maximum ambient temperature TA max
(see table: Temperature specifications) and is operated at its
nominal input voltage and output power, the temperature
measured at the Measuring point of case temperature TC(see:
Mechanical Data) will approach the indicated value TC max after
the warm-up phase. However, the relationship between TAand
TCdepends heavily on the conditions of operation and
integration into a system. The thermal conditions are influenced
by input voltage, output current, airflow and temperature of
surrounding components and surfaces. TA max is therefore,
contrary to TC max, an indicative value only.
Caution: The installer must ensure that under all operating
conditions TCremains within the limits stated in the table
Temperature specifications.
Notes: Sufficient forced cooling or an additional heat sink allows TA
to be higher than 71 °C (e.g., 85 °C) if TC max is not exceeded.
For -7 or -9 models at ambient temperature TA= 85 °C with only
convection cooling, and the maximum permissible current for each
output is approx. 40% of its nominal value as per the figure below.
Output Protection
Each output is protected against overvoltages which could occur
due to a failure of the internal control circuit. Voltage suppressor
diodes (which under worst case condition may become a short
circuit) provide the required protection. The suppressor diodes are
not designed to withstand externally applied overvoltages.
Overload at any of the outputs will cause a shut-down of all
outputs. A red LED indicates the overload condition.
Parallel or Series Connection
Single or double-output models with equal nominal output voltage
can be connected in parallel without any precautions using
Option T (current sharing).
Single output models and/or main and second outputs of double-
output models can be connected in series with any other (similar)
output.
Notes:
– Parallel connection of double output models should include both,
main and second output to maintain good regulation of both
outputs.
– Not more than 5 models should be connected in parallel.
– Series connection of second outputs without involving their main
outputs should be avoided as regulation may be poor.
– Rated output voltages above 36 V need additional measures in
order to comply with the safety requirements for SELV (Safe Extra
Low Voltage)
– The maximum output current is limited by the output with the lowest
current limitation if several outputs are connected in series.

Thermal Protection
A temperature sensor generates an internal inhibit signal which
disables the outputs if the case temperature exceeds TC max.
The outputs are automatically re-enabled when the temperature
drops below this limit.
Continuous operation under simultaneous worst-case conditions
of the following three parameters should be avoided: minimum
input voltage, maximum output power, and maximum
temperature.

Output 1 is under normal conditions regulated to Vo1 nom,
independent of output currents. Vo2 depends upon the load
distribution. If both outputs are loaded with more than 10% of Io
nom, the deviation of Vo2 remains within ±5% of the value of Vo1.
The following 3 figures show the regulation with varying load
distribution.

Sense Lines
(Only single output models)
Important: Sense lines must always be connected! Incorrectly
connected sense lines may activate the overvoltage limitation,
resulting in a permanent short-circuit of the output.
This feature allows for compensation of voltage drops across the
connector contacts and if necessary, across the load lines. If the
sense lines are connected at the load rather than directly at the
connector, the user should ensure that the voltage differences
specified in the table below are not exceeded. We recommend
connecting the sense lines directly at the female connector.
To ensure correct operation, both sense lines (S+ and S–) should
be connected to their respective power outputs (Vo1+ and Vo1–)
and the voltage difference between any sense line and its
respective power output pin (as measured on the connector)
should not exceed the following values:
Table 6: Maximum voltage compensation allowed using
sense lines
Output Total voltage difference Voltage difference
voltage between sense lines and between
their respective outputs Vo– and S–
5.1 V <0.5 V <0.25 V
12, 15, 24 V <1.0 V <0.25 V
If the output voltages are increased above Vo nom via the R-input
control, option P setting, remote sensing or option T, the output
currents must be reduced accordingly so that Po nom is not
exceeded.
Auxiliary Functions
i Inhibit for Remote On and Off
Note: With open i input the output is disabled.
The outputs may be enabled or disabled by means of a logic
signal (TTL, CMOS, etc.) applied between the inhibit input i and
the negative pin of output 1 (Vo1–). In systems with several
converters, this feature can be used to control the activation
sequence of the converters. If the inhibit function is not required,
connect the inhibit pin 18 to pin 14 to enable the outputs (active
low logic, fail safe).

Programmable Output Voltage (R-Function)
As a standard feature, the converters offer an adjustable output
voltage, identified by letter R in the type designation. The control
input R (pin 16) accepts either a control voltage Vext or a
resistor Rext to adjust the desired output voltage. When not
connected, the control input automatically sets the output
voltage to Vo nom.
a)Adjustment by means of an external control voltage Vext
between pin 16 (R) and pin 14:
The control voltage range is 0 - 2.75 VDC and allows an
output voltage adjustment in the range of approximately
0 - 110% Vo nom.
V
o
V
ext = –––––– • 2.5 V (approximate formula)
V
o nom
b) Adjustment by means of an external resistor:
Depending upon the value of the required output voltage the
resistor shall be connected
Either: Between pin 16 and pin 14 (Vo< Vo nom) to achieve
an output voltage adjustment range of approximately
0 - 100% Vo nom
or: Between pin 16 and pin 12 (Vo > Vo nom) to achieve an
output voltage adjustment range of approximately 100 - 110%
Vo nom.
Warning:
–Vext shall never exceed 2.75 VDC.
– The value of R'ext shall never be less than the lowest value
as indicated in table R'ext for (Vo > Vo nom)
Notes:
– The R-Function excludes option P (output voltage adjustment by
potentiometer).
– If the output voltages are increased above Vo nom via R-input
control, option P setting, remote sensing or option T, the output
current(s) should be reduced accordingly so that Po nom is not
exceeded.
– With double-output models the second output follows the value of
the controlled main output.
– In case of parallel connection the output voltages should be
individually set within a tolerance of 1 - 2%.

Safety and Installation Instructions
Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15/H15 S4
connector. Pin no. 24 (protective earth) is a leading pin, ensuring
that it makes contact first.
Installation Instructions
The S Series converters are components, intended exclusively for
inclusion within other equipment by an industrial assembly
operation or by professional installers. Installation must strictly
follow the national safety regulations in compliance with the
enclosure, mounting, creepage, clearance, casualty, markings and
segregation requirements of the end-use application.
Fig. 22
View of converter’s male connector
Connection to the system shall be made via the female connector
H15 (see:
Accessories
)
.
Other installation methods may not meet
the safety requirements.
The converters are provided with pin 24 ( ), which is reliably
connected with the case. For safety reasons it is essential to
connect this pin to protective earth. See:
Safety of Operator
Accessible Output Circuit
.
Input pins 30 and 32 are internally fused. Since this fuse is
designed to protect the converter in case of an overcurrent and
does not necessarily cover all customer needs, an external fuse
suitable for the application and in compliance with the local
requirements might be necessary in the wiring to one or both input
potentials, pins 26 and 28, and/or 30 and 32.

Important: When the inhibit function is not in use, pin no. 18 (i)
should be connected to pin no. 14 (S–/Vo1–) to enable the output(s).
Do not open the converters, or guarantee will be invalidated.
Due to high current values, some models provide two internally
parallel connected contacts for certain paths (pins 4/6, 8/10, 26/28
and 30/32). It is recommended to connect load and supply to both
female connector pins of each path in order to keep the voltage
drop across the connector pins at an absolute minimum and to
avoid overstress of the connector contacts with currents higher
than 8 A.
Make sure that there is sufficient airflow possible for convection
cooling. This should be verified by measuring the case
temperature when the converter is installed and operated in the
end-use application. The maximum specified case temperature
TCmax shall not be exceeded. See also Thermal Consid-erations.
If the end-product is to be UL certified, the temperature of the main
isolation transformer should be evaluated as part of the end-
product investigation.
Check for hazardous voltages before altering any connections.
Ensure that a converter failure (e.g., by an internal short-circuit)
does not result in a hazardous condition. See also: Safety of
Operator-Accessible Output Circuits.

Option -9: Extended Temperature Range
Option -9 extends the operational ambient temperature range
from –25 to 71 °C to –40 to 71 °C. The power supplies provide
full nominal output power with convection cooling. Option -9
excludes inrush current limitation by NTC.
Option E: Inrush Current Limiter
CS/DS/ES/FS/LS types may be supplemented by an electronic
circuit (option E, replacing the standard built-in NTC) to achieve
an enhanced inrush current limiting function. Option E is
mandatory for -9 models.
CS models fitted with option E and option D6 (input voltage
monitoring) meet the standard ETS 300132-2 for 48 VDC supply
voltage. Option D6 (externally adjustable via potentiometer from
36.0 to 40.5 V) is necessary to disable the converter at low input
voltages, avoiding an excessive input current. Option D6
threshold level should be adjusted to 44.0 - 50.0 V for 60 V
nominal supply systems (refer to the description of option D). The
D output can be connected directly to the inhibit input.
Note: Subsequent switch-on cycles at startup are limited to max.
10 cycles during the first 20 seconds (cold model) and then to
max. 1 cycle every 8 seconds.

An example of poor wiring for connections in parallel
(unequal length of load lines)
Option T: Current Sharing
This option ensures that the output currents are
approximately shared between all paralleled converters,
hence increasing system reliability. To use this facility,
simply interconnect the T pins of all converters and make
sure that the reference pins for the T-pin (S- for the S1000
or Vo1– for S2000) are also connected together. The load
lines should have equal length and cross section to ensure
equal voltage drop s. Not more than 5 converters should be
connected in parallel. The R-pins should be left in an open-
circuit condition. If not, prior to paralleling the Vo1 outputs
should be individually adjusted within 1 to 2%. Parallel
connection of converters with option P is not
recommended.
Option P: Potentiometer
The potentiometer allows for an output voltage adjustment
in the range of +10/–60% of Vo nom. It is accessible
through a hole in the front cover. This feature enables
compensation of voltage drops across the connector and
wiring. Option P is not recommended if models are
connected in parallel.
In double-output models both outputs are influenced by the
potentiometer setting. If option P is fitted, the R-pin 16 is
not connected.
Note: If the output voltage is increased above Vo nom via the
R-input control, option P setting, remote sensing, or option T,
the output current(s) should be reduced accordingly so that
Po nom is not exceeded.

Option D: Undervoltage Monitor
The input and/or output undervoltage monitoring circuit operates
independently of the built-in input undervoltage lockout circuit. A
logic "low" (JFET output) or "high" signal (NPN output) is
generated at pin 20 as soon as one of the monitored voltages
drops below the preselected threshold level Vt. The return for
this signal is Vo1–. The D output recovers when the monitored
voltage(s) exceed(s) Vt +Vh. The threshold levels Vti and Vto
are either adjustable by a potentiometer, accessible through a hole
in the front cover, or factory adjusted to a fixed value specified by
the customer.
Option D exists in various versions D0 - DD as shown in the
following table.

Threshold tolerances and hysteresis:
If Viis monitored, the internal input voltage after the input
filter is measured. Consequently, this voltage differs from
the voltage at the connector pins by the voltage drop ΔVti
across the input filter. The threshold levels of the D0 and
D9 options are factory-adjusted at nominal output current
Io nom and at TA= 25 °C. The value of ΔVti depends upon
the input voltage range (CS, DS, ..), threshold level Vt,
temperature and input current. The input current is a
function of the input voltage and the output power.

Option V: ACFAIL Signal (VME)
Available only for models with Vo= 5.1 V.
This option defines an undervoltage monitoring circuit for the
input and main output voltage. It generates an ACFAIL signal
(V signal) which conforms to the VME standard.
The low state level of the ACFAIL signal is specified at a sink
current of IV≤48 mA to VV≤0.6 V (open-collector output of an
NPN transistor). The pull-up resistor feeding the open-collector
output should be placed on the VME backplane.
After the ACFAIL signal has gone low, the VME standard
requires a hold-up time (th) of at least 4 ms before the 5.1 V
output drops to 4.875 V when the output is fully loaded. The
hold-up time is provided by the internal input capacitance.
Consequently, the working input voltage and the threshold level
(Vti) should be adequately above the minimum input voltage
(Vi min) of the converter so that enough energy is remaining in
the input capacitance. If the input voltage is below the required
level, an external hold-up capacitor (Ci ext) should be added.

Remarks:

to the same source voltage.

Versions V0, V2, and V3 are available as shown below.
Option V operates independently of the built-in input
undervoltage lockout circuit. A logic "low" signal is generated at

Threshold tolerances and hysteresis:
If Viis monitored, the internal input voltage is measured af ter the

filter. The threshold level of option V0 is adjusted during
manufacture at Io nom and TA= 25 °C. The value of ΔVti

level Vt, temperature and input current. The input current is a
function of input voltage and output power.

EC Declaration of Conformity
We
Power-One AG
Ackerstrasse 56, CH-8610 Uster
declare under our sole responsibility that K and S Series AC-DC and DC-DC
converters carrying the CE-mark are in conformity with the provisions of the Low
Voltage Directive (LVD) 73/23/EEC of the European Communities.
Conformity with the directive is presumed by conformity wih the following
harmonized standards:
•EN 61204:1995 (= IEC 61204:1993, modified)
Low-voltage power supply devices, DC output - Perfomance characteristics
and safety requirements
•EN 60950:2000 (= IEC 60950:2000)
Safety of information technology equipment
The installation instructions given in the data sheet describe correct installation
leading to the presumption of conformity of the end product with the LVD. All K
and S Series AC-DC and DC-DC converters are components, intended
exclusively for inclusion within other equipment by an industrial assembly
operation or by professional installers. They must not be operated as stand alone
products.
Hence conformity with the Electromagnetic Compatibility Directive 89/336/EEC
(EMC Directive) needs not to be declared. Nevertheless, guidance is provided in
most product application notes on how conformity of the end product with the
indicated EMC standards under the responsibility of the installer can be achieved,
from which conformity with the EMC directive can be presumed.
