Description

The PSS/PSK Series of positive switching regulators is

designed as power supplies for electronic systems, where no

input-to-output isolation is required. Their major advantages

include a high level of efficiency, high reliability, low output

ripple, and excellent dynamic response. Models with input

voltages up to 144 V are specially designed for secondary

switched and battery-driven mobile applications. The

converters are suitable for railway applications according to

EN 50155 and EN 50121.

Two type of housings are available allowing operation up to

71 °C. They are designed for insertion into a 19" DIN-rack or

for chassis mounting. Replacing the heat sink by an optional

cooling plate, allows chassis or wall mounting on top of a metal

surface, acting as heat sink.

Various options are available to adapt the converter to different

applications. Connector type: H15 or H15S4, depending on

output current.

Functional Description

The switching regulators are using the buck converter

topology. The input is not electrically isolated from the output.

During the on period of the switching FET, current is

transferred to the output, and energy is stored in the output

choke. During the off period, this energy forces the current to

continue flowing through the output chocke to the load and

back through the freewheeling diode. Regulation is

accomplished by varying on/off duty cycle.

These regulators are ideal for applications, where an input to

output isolation is not necessary or where it is already provided

by an external front end, e.g., a transformer with rectifier. To

optimize customer’s needs, various options and accessories

are available.

protection degree, batch no., serial no., and data code

including production site, version (modificationstatus), and

date of production.

Input Filter and Fuse

An input filter and a fuse are incorporated in all converters as

standard. The filter reduces emitted electrical noise and

prevents oscillations caused by the negative input impedance

characteristic of a switched mode regulator. The input fuse

protects against severe defects.

The maximum permissible additionally superimposed ripple vi

of the input voltage (rectifier mode) at a specified input

frequency fi has the following values:

vi max = 10 Vpp at 100 Hz, or Vpp = 1000 Hz/fi • 1 V

The input fuses are specified in the table 3.

Inrush Current

Depending on the input source and the input impedance, the

inrush current into the converter may reach a very high peak

value during the switch-on sequence. It also determine the

rating of input devices such as switches, relays, fuses, etc. To

protect these input devices by limiting the inrush current, we

recommend the choice of the active inrush current limitation

circuit, option E.

Output Protection

A voltage suppressor diode, which in worst case conditions

fails into a short-circuit, protects the output against an

internally generated overvoltage. Such an overvoltage could

occur due to a failure of either the control circuit or the

switching transistor. The output protection is not designed to

withstand externally applied overvoltages.

Current Limitation

A constant current limitation circuit holds the output current Io

almost constant in the area of 100 to 120% of Io nom, when an

overload or a short-circuit is applied to the output. It acts self-

protecting and recovers – in contrary to the fold back method –

automatically after removal of the overload or short-circuit

condition.

Parallel and Series Connection

Outputs of equal nominal voltage may be parallel-connected.

Interconnect the current sharing pins T (pin 22) for even

distribution of the output current; see Auxiliary Functions.

Outputs can be series-connected with any other regulator,

provided that the regulators are powered by electrically

isolated source voltages. In series connection the maximum

output current is limited by the lowest current limitation.

Thermal Considerations and Protection

When a switching regulator is located in free, quasi-stationary

air (convection cooling) at a temperature TA max and is operated

at its nominal output current Io nom, the case temperature TC

can rise over TC max after the warm-up phase. TC is measured

at the measuring point of case temperature; see Mechanical

Data.

Under practical operating conditions, the ambient temperature

TA may exceed TA max, provided that additional measures (heat

sink, forced cooling, etc.) are taken to ensure that the case

temperature TC does not exceed its maximum value.

The regulater is protected by an internal temperature sensor,

which inhibits the output above TC max. The output

automatically recovers, when the temperature drops below

TC max.

Auxiliary Functions

Inhibit (Remote On / Off)

The inhibit input allows to enable or disable the output with a

control signal. In systems with several regulations, this feature

can be used to control the activation sequence of the

regulators by a logic signal (TTL, C-MOS, etc.). An output

voltage overshoot will not occur, when switching on or off.

The inhibit signal is referenced to the S– (pin 18). The signal i

and the switching times are specified in table 5, fig. 5, and fig.

Note: With open i input, the output is enabled.

Sense Lines

This feature enables compensation of the voltage drop across

the connector contact s and the load lines. If the sense lines are

connected at the load rather than directly at the connector, the

user must ensure that Vo max (between Vo+ and Go–) is not

exceeded.

Applying generously dimensioned cross-section load leads

reduces the voltage drop. To minimize noise pick-up, the

sense lines should be wired in parallel or twisted.

To ensure correct operation, both sense lines must be

connected to their respective power output. The voltage

difference between any sense line and its respective power

output pin (as measured on the connector) should not exceed

the values given in table 4.

Note: Sense lines should always be connected! It is

recommended to connect the sense lines directly at the female

connector.

Current Sharing

For parallel operation of several regulators, interconnect all T-

pins to ensure that the output currents are evenly distributed.

This feature improves transient load performance and

increases system reliability. All paralleled regulators should be

supplied by equal input voltage (Vi). The output lines should

exhibit equal length and cross section to provide equal voltage

drop.

Installation Instruction

Installation of the regulators 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.

The input and the output circuit are not separated. The

negative path is internally interconnected.

The regulators should be connected to a secondary circuit.

Make sure that a regulator failure (e.g. by an internal short-

circuit) does not result in a hazardous condition.

Do not open the regulator!

Standards and Approvals

All switching regulators are class-I equipments and have been

approved according to UL 60950, CSA 60950, and IEC/EN

60950.

The regulators have been evaluated for:

• Building in

• Operational insulation from input to output and input/output

to case

• The use in a pollution degree 2 environment

• Connecting the input to a secondary circuit, which is subject

to a maximum transient rating of 1500 V.

The switching regulators are subject to manufacturing

surveillance in accordance with the above mentioned

standards and with ISO 9001:2000.

Cleaning Agents

In order to avoid possible damage, any penetration of cleaning

fluids must be prevented, since the regulators are not

hermetically sealed.

Protection Degree

The protection degree is IP 30 (IP 20, if equipped with

option P). It applies only, if the regulator is plugged-in or

the matching female connector is properly attached.

Isolation and Protective Earth

The resistance of the protective earth connection (max.

0.1 Ω) is tested. Also the electric strength between the

input interconnected with the output and the case is

tested with 500 VDC (all -2 models), 750 VDC (models

with Vi max = 80 V), or 1500 VDC (models with Vi max =

144), ≥1 s.

These tests are performed in the factory as routine test

in accordance with EN 50116 and IEC/EN 60950. The

electric strength test should not be repeated by the

customer. Power-One will not honor any warranty

claims resulting from electric strength tests.

Railway Application

The regulators have been developed observing the

railway standards EN 50155 and EN 50121. All boards

are coated with a protective lacquer.

Description of Options

-9 Extended Temperature Range

This option defines an extended temperature range as

specified in table 10.

P Potentiometer to Adjust the Output

Note: Option P is not recommended, if several regulators are

operated in parallel connection.

Option P excludes R function; the R-input (pin 16) should be

left open-circuit. The output voltage Vo can be adjusted in the

range 90 - 110% of Vo nom.

However , the minimum dif ferential voltage Vi max between input

and output as specified in Electrical Input Data should be

maintained.

E Inrush Current Limitation

Note: This option requires an increased minimum input voltage

Vi max of up to 1 V, dependent upon input range.

In regulators without option E, after application of the input

supply the inrush current is limited by parasitic components of

the voltage source and the regulator input only. The regulator

input exhibits a very low impedance, and when driven from a

low impedance source, for example a battery, the inrush

current can peak at several orders of magnitude above the

continuous input current.

Option E dramatically reduces this peak current and is

recommended for any application to protect series elements

such as fuses, switches, or circuit brakers. The st artup circuit is

bypassed during normal operation.

C Thyristor Crowbar

Note: The crowbar can be reset by removal of the input voltage

only. The inhibit signal cannot deactivate the thyristor.

Option C protects the load against power supply malfunction. It

is not designed to sink external currents.

As a central overvoltage protection device, the crowbar is

usually connected to the external load via distributed

inductance of the lines. For this reason, the overvoltage at the

load can temporarily exceed the trigger voltage Vo c.

Depending on the application, further decentralized

overvoltage protection elements may have to be used

additionally.

A fixed-value monitoring circuit checks the output voltage Vo,

and when the trigger voltage Vo c is reached, the thyristor

crowbar triggers and disables the output.

An external connection C (crowbar trigger control) is provided.

When crowbar option is used with two or more power supplies

in parallel connection, all crowbar trigger terminals (C) should

be interconnected. This ensures all crowbar circuits triggering

simultaneously, in order to disable all outputs at once. The

crowbar trigger voltage is maintained between Vo+ and Go–.

To prevent false triggering, the user should ensure that Vo

(between Vo+ and Go–) deos not exceed Vo c.

Where a cooling surface is available, a cooling plate (option B

or option B1) can be fitted instead of the standard heatsink.

The mounting system must ensure sufficient cooling capacity

to guarantee that the maximum case temperature TC max is not

exceeded. The required cooling capacity can be calculated by

the following formula:

EC Declaration of Conformity

Power-One AG

Ackerstrasse 56 CH-8610 Uster

declare under our sole responsibility that all PSx Series switching regulators carrying the

CE-mark are in conformity with the provisions of the Low Voltage Directive (LVD) 2006/95/

EC 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: 1992 + A1: 1993 + A2 (= IEC 950 second edition 1991 + A1: 1992 +

A2: 1993) - Safety of information technology equipment

The installation instructions given in the corresponding data sheet describe correct installation

leading to the presumption of conformity of the end product with the LVD. All PSx Series

Switching Regulators 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.
