Summary
The M series 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 lock-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 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
39
1.54"
8 TE
168
6.6"
agencies LGA (Germany) and UL (USA). The UL Mark for
Cana-da has been officially recognized be 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
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.

Functional Description
DC-DC Converters
M Series
The input voltage is fed via an input fuse, an input filter, a
rectifier
3
and an inrush current limiter
4
to the input capaci-
tor. 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
U
o1
and generates, with respect to the maximum
admissible output currents, the control signal for the pri-
mary switching transistor. This signal is fed back via a cou-
pling transformer.
The auxiliary outputs
U
o2
and
U
o3
are individually regulated
by means of secondary switching transistors. Each aux-
iliary 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 main control cir-
cuit.
