J WIRING
To prevent incorrect wiring of the input/output terminals, pay
attention to their polarities.
J BATTERY CHARGING
When connecting a battery to the load, install an overcurrent limit
circuit and overvoltage protection circuit.
J SERIES OPERATION
S82K 90-W/100-W/240-W models can be operated in series.
It must be noted that the + output of the 7.5-W dual output model
cannot be connected in series to its – output.

J PARALLEL OPERATION
S82K 90-W/100-W/240-W models can be operated in parallel.
Perform parallel operation with power supplies satisfying the
same specifications.

Parallel Operation Precautions
Minimum Output Current
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
Operating and Storage Environments
To avoid deterioration of the operating characteristics or
malfunction, do

The length and thickness of each wire connected to the
load must be the same so 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 so there
will be no difference in output voltage between each Power
Supply.
If the 240-W Power Supply is used in single operation un-
der the parallel operation setting, the overcurrent protection
will be actuated at an output of 90% to 95% (in current) and
will not allow a 100% output.
If the 240-W Power Supplies are used in parallel operation
under the single operation setting, one of them will operate
at 110% output, causing severe heat derating and
shortening the service life.

rent falls to 10% or less of the rated output, the –V
output voltage may drop.

Ambient operating temperatures outside the range indi-
cated by the derating curve.
Ambient operating humidity outside the range of 25% to
85%.
Condensation as the result of severe changes in
temperature.
Ambient storage temperatures outside the range of
–25 C to 65 C.
Corrosive or flammable gases.
Dust (especially iron dust) or salts.
Shock or vibration.
Exposure to water, oil, or chemicals.
