Double-output models exhibit an independent
control logic each. Both outputs can be connected
in parallel, provided that the options S (included in
M1) and R are not used, since they influence only

the 2 nd output. The two pairs of powertrains share
the current due to their output voltage droop
characteristic.
Up to 3 converters with the same output voltage
may be operated in parallel. It is possible to parallel
W Series with X Series converters.
Reasonable current sharing is achieved by the
droop characteristic. Correct mode of operation is
highly dependent upon the wiring of the converters
and the impedance of these wires. Use wires with
equal length and equal cross sections of min. 1.5
mm 2 . The best results for parallel operation can be

achieved with the wiring shown in fig. 6.
Parallel operation of single-output models using
option R (output voltage adjust) is possible, but not
recommended. Refer to fig. 6; the connections
between the pins 8 and 9 (both Vo –) should be as
short as possible.

eliminates the output voltage droop.
Series Connection
Series connection of several outputs up to 150 V is
possible. The output is not SELV, when the max.

Additional wiring for output currents I o ≥ 10 A
Additional wiring, if using the R-input
charging of capacitors; see fig. 8.
Each output is independently protected against
internal overvoltage by means of a second control
loop. When the output voltage exceeds V o L , the

Overtemperature Protection
Each powertrain is independently protected against over-
temperature by a built-in temperature sensor. When a certain
temperature is reached, the concerned powertrain reduces
its output power continuously.
