Features include high efficiency, reliability, low output voltage noise and excellent dynamic response to load/line changes due to individual regulation of each output. The converter inputs are protected against surges and transients occuring at the source lines. An input over- and undervoltage lockout circuit disables the outputs, if the input voltage is outside the specified range. An inrush current limitation prevents 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 the connector (pin 2). If the inhibit function is not used, pin 2 should be connected to pin 23 to enable the outputs. LED indicators display the status of the converter and allow visual monitoring of the system at any time. Table of Contents 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 standard IEC/EN 60950-1 and UL/CSA 60950-1, and they have been approved by the safety agencies TUV and UL. 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 should remain below 95 C under all conditions. A temperature sensor generates an inhibit signal, which disables the outputs, when the case temperature TC exceeds the limit. The outputs automatically recover, 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 60927-3 or be mounted onto a chassis or a plate.

BCD20018 Rev AB Page 3 of 26 www.power-one.com M Series Data Sheet 50 Watt DC-DC and AC-DC Converters (R) Functional Description The input voltage is fed via an input fuse, an input filter, a rectifier, 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 ripples smoothed by a power choke and an output filter. The main control circuit senses the main output voltage Vo1 and generates, with respect to the maximum admissible output currents, the control signal for the primary switching transistor. This signal is transferred to the primary side by a coupling transformer. The auxiliary output voltages Vo2 and Vo3 are individually regulated by means of secondary switching transistors. Each auxiliary output's current is sensed using a current transformer. If one of the outputs is driven into current limit, the other outputs will reduce their output voltages as well, because all output currents are controlled by the same main control circuit. 03009a Option P Main control circuit CY 5 Vi+ 29 L 5 Vi- Input filter Fuse 1 2 3 32 Forward converter approx. 70 kHz N Output 1 filter 2 i 5 D, V 14 R4 17 G4 20 23 CZ Control circuit output 2 5 Output 2 filter 14 17 CZ Control circuit output 3 Output 3 filter 8 11 26 CY 1 2 3 4 5 Transient suppressor diode in AM, BM, CM, FM models.

BCD20018 Rev AB Page 5 of 26 www.power-one.com M Series Data Sheet 50 Watt DC-DC and AC-DC Converters (R) Input Fuse Input Under-/Overvoltage Lockout A fuse holder containing a slow-blow type fuse (size: 5 x 20 mm) is mounted in the back plate of the converter. The fuse protects the converter against severe defects. It may not fully protect it at input voltages exceeding 200 VDC. In applications, where the converters operate at DC source voltages above 200 VDC, an external fuse or a circuit breaker at system level should be installed. If the input voltage remains below 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 must be carefully considered (see table Input data). The fuse and a VDR form together with the input filter an effective protection against high input transients. Note: For applications, where the fuse should not be accessible; see Option F.

Reverse Polarity Reverse polarity at the input of AM, BM, CM, DM, and FM models will cause the fuse to blow. In EM and LM models a series diode will protect the converter. A series diode is not incorporated in AM, BM, CM, DM and FM types to avoid unwanted power losses. Inrush Current The CM, DM, EM, and LM (excluding FM) models incorporate an NTC resistor in the input line, which (during the initial switch-on cycle) limits the peak inrush current in order to prevent the connectors and switching devices from damage. Subsequent switch-on cycles within a short interval will cause an increase of the peak inrush current due to the warming-up of the NTC resistor. Refer to Option E.

Notes: Sufficient forced cooling or an additional heat sink allow TA to pass over 71 C, if TC max is not exceeded.

It is important to assure that the main output of a multiple-output converter is forced to supply a minimum current of 0.1 A to enable correct operation of its own auxiliary outputs. In parallel operation, one or more of the main outputs may operate continuously in current limitation, causing an increase of the case temperature TC. Consequently, a reduction of the max. ambient temperature by 10 K is recommended. Fig. 5 Dynamic load regulation Vo d versus load change. Thermal Considerations and Protection 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 TA and TC depends heavily on the conditions of operation and integration into a system. The thermal conditions are influenced by input voltage, output current, airflow, and BCD20018 Rev AB Parallel and Series Connection Main or auxiliary outputs can be connected in series with any other output of the same or another converter. In series connection, the maximum output current is limited by the lowest current limit. Output ripple and regulation values are added. Connection wiring should be kept as short as possible. If output terminals are connected together in order to establish multi-voltage configurations, e.g., +5.1 V, 12 V etc., the common-ground connecting point should be as close as possible to the connectors of the converter in order to avoid excessive output ripple voltages. Note: Auxiliary outputs should never be connected in parallel! Page 8 of 26 www.power-one.com M Series Data Sheet 50 Watt DC-DC and AC-DC Converters (R) Output Current Allocation for Special Models Output currents differing from those given for standard models (see Model Selection) can be provided on request. A maximum output power of 50 W should be considered, if an ambient temperature range of - 40 to 71 C is required. The maximum permissible output currents are indicated in the table below. If the output voltages are different from standard values, the relevant output currents have to be adapted accordingly. With reduced maximum ambient temperature or with forced cooling, the total output power may exceed 50 W. Customized configurations always need to be checked by a feasibility study first.

Hold-up Time and Output Response When the input voltage is switched off, the output voltage will remain high for a certain hold-up time t h (see fig. 7) before the output voltage falls below 0.95 Vo nom. To achieve the hold-up times indicated in fig. 8, AM, BM, CM, DM, and FM models require an external series diode in the input line. This is necessary to prevent the discharge of the input capacitor through the source impedance or other circuits connected to the same source. EM and LM models have a built-in series diode. In AM, BM, CM, DM, and FM models, no series diode is built-in, since it would generate additional power losses inside the converter. The behavior of the outputs is similar with either the input voltage applied or the inhibit switched low. No output voltage overshoot occurs, when the converter is turned on or off. th [ms] 05024a 1000 LM EM Note: For hold-up time with option V, refer to Option V. 100 CM/DM AM/BM/FM Vo/Vo nom 05025a 0.95 10 0.1 0 tr Vi tf t th 1 0 1 t Inhibit 1 0 t 0.1 1 2 3 4 5 6 Fig. 7 Fig. 8 Output response times versus Vi or inhibit control Typical hold-up time t h versus input voltage at Io nom BCD20018 Rev AB Page 9 of 26 Vi DC ______ Vi min DC www.power-one.com M Series Data Sheet 50 Watt DC-DC and AC-DC Converters (R) Table 6: Output response time t r and t f (see fig. 7).

For multiple-output models the figures indicated in the table relate to the output, which reacts slowest. All outputs are resistively loaded. Variation of the input voltage within Vi min - Vi max does not influence the values considerably. Auxiliary Functions Inhibit Iinh [mA] The outputs of the converters 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, for example, to control the activation sequence of the converters. If the inhibit function is not required, connect the inhibit pin 2 to pin 23 to enable the outputs (active low logic, fail safe).

Note: With open R input, Vo = Vo nom. The output voltage Vo can either be adjusted by an external voltage (Vext) or by an external resistor (Rext1 or Rext2). The adjustment range is approximative 0 - 110% of Vo nom. For output voltages Vo > Vo nom, the minimum input voltage Vi min specified in Electrical Input Data increases proportionally to Vo/Vo nom. a) Adjustment by means of an external resistor Rext. Depending upon the value of the required output voltage, the resistor shall be connected: either: Between the R and G pin to achieve an output voltage adjustment range of Vo 0 to 100 % of Vo nom.

This should be verified by measuring the case temperature TC, when the converter is installed and operated in the end-use application. The maximum specified case temperature TC max shall not be exceeded. See also Thermal Considerations. Cleaning Agents In order to avoid possible damage, any penetration of liquids (e.g., cleaning fluids) has to be prevented, since the power supplies are not hermetically sealed. Operation of LM Models at Greater than 63 Hz In such a case, the converters may exceed the leakage current of 3.5 mA imposed in the safety standards. A warning marking is required in the end-use product. Installation Instructions All M Series converters are components, intended exclusively for inclusion within other equipment 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. Connection to the system shall be made via the female connector H11. Other installation methods may not meet the safety requirements. The converters are provided with the leading pin 26 ( ), which is reliably connected with the case. For safety reasons, it is essential to connect pin 26 with the protective earth of the supply system. An input fuse is connected in the line to pin 32 (Vi- or L ). 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 may be necessary in the wiring to one or both input pins (no. 29 and/or no. 32), particularily if the phase or neutral line cannot be assigned to the corresponding terminals (LM models operated with AC). BCD20018 Rev AB Important: Whenever the inhibit function is not in use, pin 2 (i) should be connected to pin 23 (Vo-) to enable the output(s). Caution: Do not open the converters, or warranty will be invalidated. 3 DC input voltage DC input voltage View of male H11 connector. Protection Degree Condition: Female connector fitted to the converter. IP 40: All models, except those with options P or A, and except those with option D/V with potentiometer.

Railway Applications The M Series converters have been designed observing the railway standards EN 50155 and EN 50121. All boards are coated with a protection lacquer. Standards and Approvals The converters correspond to class I equipment and have been approved according to the standards IEC/EN 60950-1 and UL/CSA 60950-1. Page 17 of 26 www.power-one.com M Series Data Sheet 50 Watt DC-DC and AC-DC Converters (R) The converters have been evaluated for: * Class I equipment * Building in * Basic insulation between input and case and double or reinforced insulation between input and output, based on the input voltage of 250 VAC or 400 VDC * Functional insulation between output(s) and case * Functional insulation between the outputs * Pollution degree 2 environment * Overvoltage catagory II * Altitude up to 2000 m The converters are subject to manufacturing surveillance in accordance with the above mentioned standards and with ISO 9001:2000. Isolation The electric strength test is performed in the factory as routine test in accordance with EN 50116 and IEC/EN 60950, and should not be repeated in the field.

The earth connection has to be provided by the installer according to the safety standard IEC/EN 60950. The following table shows a possible installation configuration, compliance with which causes the output circuit of the DC-DC converter to be an SELV circuit according to IEC/EN 60950 up to a configured output voltage (sum of nominal voltages if in BCD20018 Rev AB series or +/- configuration) of 48 V. However, it is the sole responsibility of the installer to assure the compliance with the relevant and applicable safety regulations.

Option -7 stays for the operational ambient temperature range from -25 to 71 C, which may be preferred by some customers for reasons of documentation or approvals. A Test Sockets Test sockets (pin O = 2 mm, distance d = 5.08 mm) are located at the front of the converter. The output voltage is sensed at the connector pins inside of the converter. Outputs 2 and 3 of triple-output models are not sensed. P Potentiometer Built-in multi-turn potentiometers provide an output voltage adjustment range of minimum 5% of Vo nom and are accessible through holes in the front cover. Compensation of voltage drop across connector and wiring becomes easily achievable. For output voltages Vo > Vo nom , the minimum input voltage according to Electrical Input Data increases proportionally to Vo /Vo nom . Triple-output models allow only the adjustment of Vo1. Note: Potentiometers applications. are not recommended for limitation, an active electronic circuit as shown in fig. Option E block diagram has been developed. Typical inrush current waveforms of units equipped with this option are shown below. CM models meet the CEPT/ETSI standards for 48 V supply voltage according to ETS 300132-2, if fitted with option E combined with option D6 (input voltage monitoring). Option D6, externally adjustable via potentiometer, is necessary to disable the converter at input voltages below the actual service ranges, avoiding an excessive input current when the input voltage is raised slowly according to ETS 300132-2. Option D6 threshold level Vt i + Vh i (refer to description of option D) should be adjusted to 36 - 40.5 V for 48 V nominal supply voltage (for 60 V systems, threshold should be set to 44 - 50 V). The D output (pin 5) should be connected to the inhibit (pin 2). For applications, where potentiometers are not allowed, refer to option D9. 11018a mobile E Electronic Inrush Current Limitation Control logic FET Rectifier (LM models) Available for CM, EM and LM models.

Fig. 19 D Undervoltage Monitor Typical inrush current waveforms of CM, EM, and LM converters with option E Precautions: In order to avoid overload of the series resistor RI, the on/off switching cycle should be limited to 12 s, if switched on/off continuously. There should not be more than 10 start-up cycles within 20 s at a case temperature of 25 C. If CM models are driven by input voltages below 35 VDC or LM models below 100 VAC, the maximum case temperature should be derated by 10 C, or the total output power should be derated by 20%. EM and LM models driven The input and/or output undervoltage monitor operates independently of the built-in input undervoltage lock-out circuit. A logic "low" (JFET output) or "high" signal (NPN output) is generated at pin 5, when one of the monitored voltages drops below the preselected threshold level Vt. The return for this signal is Vo1- (pin 23). The D output recovers, when the monitored voltage(s) exceed(s) Vt + V h. The threshold level Vt is either adjustable by a potentiometer accessible through a hole in the front cover, or adjusted in the factory to a fixed value specified by the customer. Option D exists in various versions D0 - D9, as shown in table 20.

VD - 0.4 V (logic low) corresponds to a monitored voltage level (Vi and/or Vo1) < Vt. The current I D through the JFET should not exceed 2.5 mA. The JFET is protected by a 0.5 W Zener diode of 8.2 V against external overvoltages. If V i is monitored, the internal input voltage after the input filter and rectifier (EM and LM types) is measured. Consequently, this voltage differs from the voltage at the connector pins by the voltage drop V ti across input filter and rectifier. The threshold level of the D0 and D9 options is adjusted in the factory at nominal output current Io nom and TA = 25 C. The value of V ti depends upon input voltage range (AM, BM, etc.), threshold level Vt, temperature, and input current.

This option defines an undervoltage monitoring circuit for the input or the input and main output voltage equivalent to option D and generates the 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 BCD20018 Rev AB output). 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 t h of at least 4 ms before the 5.1 V output drops to 4.875 V, when the 5.1 V output is fully loaded. This hold-up time t h is provided by the internal input capacitance. Consequently the working input voltage and the Page 22 of 26 www.power-one.com M Series Data Sheet 50 Watt DC-DC and AC-DC Converters (R) 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.

A decoupling diode should be connected in series with the input of AM, BM, CM, DM, and FM converters to avoid the input capacitance discharging through other loads connected to the same source voltage.
