Wiring
Carefully wire the input/output terminals while paying attention to
their polarities so as to prevent incorrect wiring.
Battery Charging
When connecting a battery to the load, install an overcurrent limit
circuit and overvoltage protection circuit.
Series Operation
S82K 90-W/100-W/240-W model 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.

Note:
When operating the 240-W model in parallel operation, set
the switch to “PARALLEL.” Refer to the derating curve for

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 so that there will
be no difference in output voltage between each Power Supply.
•
If the 240-W Power Supply is used in single operation under 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.
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 are
controlled by the +V output. If the +V output current falls to
10% or less of the rated output, the –V output voltage may
drop.
Operating and Storage Environments
Do not use or store the Unit in the following places, otherwise the
Unit may malfunction or the characteristics of the Unit may deterio-
rate.
•
Locations subject to direct sunlight.
•
Locations subject to ambient operating temperatures outside the
range indicated by the derating curve.
•
Locations subject to ambient operating humidity outside the
range of 25% to 85%.
•
Locations subject to condensation as the result of severe
changes in temperature.
•
Locations subject to ambient storage temperatures outside the
range of –25
°
C to 65
