Description  
The M-family of DC-DC (AC-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.  
to output isolation is provided. 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 be regulatory authorities in  
provinces across Canada.  
The converter inputs are protected against surges and tran-  
sients occuring at the source lines. An input over- and  
undervoltage cut-out circuitry disables the outputs if the in-  
put voltage is outside the specified range. Certain types in-  
clude an inrush current limitation preventing circuit break-  
ers and fuses from being damaged at switch-on.  
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 TC exceeds the  
limit. The outputs are automatically re-enabled when the  
temperature drops below the limit.  
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.  
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.  
LED indicators display the status of the converter and allow  
visual monitoring of the system at any time.  
Case: aluminium, black finish, self cooling.  
Dimensions: 38.7 × 111.2 × 168.5 mm. Weight: 770 g.
