Series Operation; Parallel Operation - Omron S82K-00305 Manual

Series Operation

Two Power Supplies can be operated in series.
Only 90-W/100-W models can be operated in series.
Series operation, however, is not possible for the + outputs and –
outputs of models with ± outputs.

ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.

Parallel Operation

S82K 100-W models can be operated in parallel.
Perform parallel operation with power supplies satisfying the same
model.

Note: When operating the S82K-P10024 in parallel operation, set the
selector to "PARALLEL. In this case, the rated current per
S82K-P10024 is 3.78 A.

Parallel Operation Precautions
The length and thickness of each wire connected to the load must be
the same so that there is no difference in voltage drop value between
the load and the output terminals of each Power Supply.
Adjust the output voltage of each Power Supply with output voltage
adjuster (V. ADJ) so that there will be no difference in output voltage
between each Power Supply.
Minimum Output Current
(S82K-00727/S82K-00728)
The minimum output current of the S82K-00727 and S82K-00728 is
restricted by the output voltage and control method.
Note: All the outputs of the S82K-00727 and S82K-00728 are
controlled by the +V output. If the +V output current falls to
more than 10% of the rated output, the –V output voltage may
drop.
