W Series Data Sheet
125, 250 Watt AC-DC and DC-DC DIN-Rail Converters
Parallel Operation
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 2nd 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 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.
Note: Parallel operation is not possible, if the
temperature sensor is connected, as the sensor
eliminates the output voltage droop.
Series Connection
Series connection of several outputs up to 150
V is possible. Exceeding an output voltage of
60 V, the output is not SELV.
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
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
Vo L,
the
respective
output
is
disabled.
Overtemperature Protection
A built-in temperature sensor protects each powertrain is
independently protected against overtemperature. When a
certain temperature is reached, the concerned powertrain
reduces its output power continuously.
