Summary

The M series of AC-DC (DC-DC) converters represents a

broad and flexible range of power supplies for use in ad-

vanced industrial electronic systems. 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 tran-

sients occuring at the Input. An input over- and under-

voltage lock-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 suppressor

diodes. The outputs can be inhibited by a logic signal ap-

plied to the connector pin 2 (i). If the inhibit function is not

used pin 2 should be connected to pin 23 to enable the out-

puts.

LED indicators display the status of the converter and allow

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 modules are designed

and built according to the international safety standard

IEC/EN 60950 and have been approved by the safety agen-

1.54"

8 TE

168

6.6"

cies LGA (Germany) and UL (USA). The UL Mark for

Canada has been officially recognized by regulatory au-

thorities in provinces across 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 should remain below 95°C under all

conditions.

A temperature sensor generates an inhibit signal which

disables the outputs if the case temperature

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" rack systems

according to DIN 41494, or be chassis mounted.
