Wiring
Carefully wire the input/output terminals while paying attention to
their polarities so as to prevent incorrect wiring.
Battery Charging/Backup
With S82K-j09024/-j10024/-24024T models, a reduction in life-
time due to over discharge of the battery can be prevented using the
DC LOW output. (Discharge can be interrupted at 0.75 to 0.9 $
24 V.)

Note: 1. For details of charging voltages and charging currents,
refer to the specifications for the battery.
2. In order to prevent overvoltage to the battery, install an
overvoltage protection circuit (90/100-W models).
3. To protect the battery in the event of incorrect operation,
such as load short-circuiting, be sure to install a fuse or
circuit breaker.
4. To limit the level of charging current to the battery, install
an overcurrent limit circuit.
With other models, 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.

Parallel Operation
S82K 100-W/240-W models can be operated in parallel.
Perform parallel operation with power supplies satisfying the same
specifications.

Note: When operating the S82K-P10024 or S82K-j24024j in
parallel operation, set the switch to "PARALLEL." Refer to
the derating curve for the rated current under this operation.

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.
