Parallel Operation
?
125, 250 Watt AC-DC and DC-DC DIN-Rail Converters
11054b
Double-output models exhibit an independant
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 power trains 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 the option R (output voltage adjust) is
possible, but not recommended. Refer to fig.

(both Vo –) should be as short as possible.
Note : Parallel operation is not possible, if a
temperature sensor is connected, as the
sensor eliminates the output voltage droop.
Note : For ORing diodes, we recommend to
use Schottkydiodes, mounted on a commun

Output Characteristic and Protection
The output characteristic, individual for each
powertrain, is rectangular with a droop to ease
parallel operation; see fig. 7.
However, a 50% higher output current is

for higher output currents and with the use of option R is shown.
possible for a short time, such allowing start-
up of loads or 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 respective output is disabled.
Overtemperature Protection
A built-in temperature sensor protects each powertrain is
