Features include high efficiency, reliability, low output voltage noise and excellent dynamic response to load/line changes due to individual reguiation of each output. The converter inputs are protected against surges and tran- sients occuring at the Input. An input over- and under- voltage cut-out circuitry disables the outputs if the input voltage is outside the specified range. These types include an inrush current limitation preventing circuit breakers and fuses from being damaged at switch-on. All outputs are open- and short-circuit proof and are pro- tected against overvoltages by means of built-in suppres- sor diodes. The outputs can be inhibited by a logic signal applied to the connector pin 2 (i). If the inhibit function is not used pin 2 should be connected with pin 23 to enable the outputs. LED indicators display the status of the converter and allow visual monitoring of the system at any time.

The modules are designed and built according to the international safety standard IEC 950 and have been approved by the safety agencies LGA (Germany) and UL (USA). The UL Mark for Canada has been officially recognized by regulatory authorities in provinces across Canada. The case design allows operation at nominal load up to an ambient temperature of 71C in free air. If forced cooling is provided, the ambient temperature may exceed 71C but the case temperature should remain below 95C under all conditions. A temperature sensor generates an inhibit signal which disables the outputs if the case temperature Tc exceeds the limit. The outputs are automatically re-enabled when the temperature drops below the limit. Various options are available to adapt the converters to in- dividual applications. The modules may either be plugged into 19 inch rack sys- tems according to DIN 41494, or be chassis mounted. Case: aluminium, black finish, self cooling. Dimensions: 38.7 x 111.2 x 168.5 mm.

If the output circuit of an AC-DC converter is operator-ac- cessibie according to the IEC 950 related safety standards, it shall be an SELV circuit (Safety Extra Low Voltage circuit, i.e. a circuit, separated from mains by at least basic insula- tion, that is so designed and protected such that under nor- mal and single fault conditions, the voltage between any two conductors and between any conductor and earth does not exceec! 60 V DC). In the following section an interpretation is provided of the IEC 950 safety standard with respect to the safety status of the output circuit. However, it is the sole responsibility of the installer or user to assure the compliance with the re- levant and applicable safety standards: If the AC-DC converter is installed according to the relevant safety regulations its outputs are considered to be SELV circuits up to a nominal output voitage of 36 V.

In class | equipment the connector protective earthing pin is leading while it is omitted in class II equipment (no protec- tive earthing is required). Class Il equipment provides rein- forced insulation between input and output circuitry and also between input and case. There are two class Il Y-ca- pacitors connected in series between input and output cir- cuitry instead of having Y-capacitors connected to the case. Important Advice AC-DC Converters <100 Ww Rugged Environment During the production process, all transformers and each of the fully assembled modules are individually tested for elec- tric strength and earth continuity (see "Supplementary Data"). All electric strength tests are performed as factory tests. The UL 1950 recognition limits the maximum ambient op- erational temperature of the standard modules to Ta Ta max -15 K. Option U allows the operation in applications where the full operational temperature range according to the relevant data sheet and UL 1950 recognition is re- quired. Electric strength tests should not be repeated in.the field. Improper test methods, for example overshooting or oscillating test voltages, ' voltage slopes exceding 1 kV/us, internal Y-capacitors not carefully discharged, ele. can cause severe damage to switching devices and ICs. Melcher AG will not honour any guarantee/warranty claims resulting from high voltage field tests. Installation Instructions Installation of the power supply must strictly follow the na- tional safety regulations. To observe the safety require- ments according to EN 60950/IEC 950, the module shall be connected via the female connector type H11 (see section Accessories'). Other installation methods may not meet the saety requirements. A second fuse should be installed in the wiring to pin 29 if: Table 3: H11 connector pin allocation ~ Local requirements demand an individual fuse in each source line Neutral to earth impedance is high or undefined Phase and neutral of the mains are not defined Wheriever the inhibit function is. not required, pin.2 (i) should be connected to pin. 23 te enable the output(s).

This capacitor sources a single transistor forward con- verter 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 control logic senses the main output voltage Up; and generates, with respect to the maximum admissible output currents, the control signal for the pri- AC-DC Converters <100 W M-Family mary switching transistor. This signal is fed back via a cou- pling transformer. The auxiliary outputs Us2 and Up; are individually regulated by means of secondary switching transistors. Each auxili- ary output's current is sensed using a current transformer. If one of the outputs is driven into current limit, the other out- puts will reduce their output voltages as well because all output currents are controlled by the same control circuit.

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 ail outputs. A red LED indicates the overload condition of the respective output. Parallel and Series Connection Main outputs of equal nominal voltage can be connected in parallel. It is important to assure that the main output of a multip'e output module is forced to supply a minimum cur- rent 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 limit which will cause an in- crease in case temperature. Consequently, a reduction of the max. ambient temperature by 10 K is recommended. Main or auxiliary outputs can be connected in series with any other output of the same or another module. 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 possi- bie. lf output terminals are connected together in order to estab- lish multi-voltage configurations, e.g. +5.1 V, +12 V etc. the common ground connecting point should be as close as possible to the connector of the converter to avoid exces- sive output voltage noise. Auxiliary outputs should never be connected in parallel!

Option E Extended inrush current limitation Available for C/E/LM and C/LMZ types. The standard versions include a passive inrush current limitetion in form of a NTC resistor. For applications which require an extended inrush current limitation, an active electronic circuit as shown in option E "Block diagram" has been developed. Typical inrush cur- rent waveforms of units equipped with this option are shown below. Precautions: In order to avoid overload of the series resistor R, 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 ternperature of 25C. lf the modules are driven by an input voltage below 100 V AC, the maximum case temperature should be derated by 10 K or the total output power should be derated by 20%. Units driven by DC input voltages do not need to be derated within the full specified input voltage range. Availability: Opticn E is available with a nominal output power of 51 W maximum.

The low state level of the ACFAIL signal is specified at a sink current of 4y = 48 mA to Uy < 0.6 V (open-coliector out- put of a NPN transistor). The pull-up resistor feeding the open-collector output should be placed on the VME back- plane. After the ACFAIL signal has gone low, the VME standard requires a hold-up time , 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 fy is provided by the internal input capacitance. Consequently the working input voltage and the threshold level LU; should be adequately above the mini- mum :nput voltage U, min of the converter so that enough energy is remaining in the input capacitance.

MELCHER The Power Partners 10-18 Edition 1/96 - Meicher AGRugged Environment Option F Fuse not accessible The standard M units have a fusehoider containing a 5 x 20 mm fuse which is externally accessible and to be found in the back plate near the connector. Some applications re- quire an inaccessible fuse. Option F provides a fuse moun- ted directly onto the main PCB inside the case. The full self-protecting functions of the module do normally not lead to broken fuses, except a power component inside fails (switching transistor, freewheeling diode, etc). In such cases the defective unit has to be returned to Melcher for repair. Immunity to Environmental Conditions Table 21: Mechanical stress AC-DC Converters <100 W M-Family Option U UL version Underwriters Laboratories (UL) have approved the M se- ries converters as recognized components up to an ambi- ent temperature of Ta max ~ 15 K given by the upper tem- perature limit of the standard PCB material. If the full maxi- mum ambient temperature Ta max is required with UL ap- proval, option U should be requested. It consists of an alter- native PCB material with a higher maximum temperature specification. The European approval boards have in contrast accepted the converters with the standard PCB material to be oper- ated up to Ts max without any further precautions.
