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.
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.
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.
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 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 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
T
C
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.
