Generating Output Voltage (±)
An output of ± can be generated by using two Power Supplies as
shown below, because the Power Supply produces a floating output.

If operation amplifiers as loads are connected in series, connect a
diode between the positive and negative output terminals of each
Switching Power Supplies as shown in the illustration below. Without
these diodes, the Power Supply may not start when power is turned
on, possibly damaging internal circuits over a period of time.
Use Schottky barrier diodes with a low forward voltage (V_F). Other
types of diodes will not be effective.
Guidelines for the dielectric strength and current of the diodes are as
follows:
Dielectric strength: At least twice the rated output voltage of the
Power Supply
Forward current: At least twice the rated output
current
No diodes are required for models that allow series operation.

Series Operation
Only models with power ratings of 50/100/150/300/600 W allow
series operation.
As shown in the following diagram, the output voltage from each
Switching Power Supply can be added.

With the S82J-050@@@@ or S82J-10024@@, if the load is shorted a
reverse voltage may result in the Power Supply causing deterioration
and damage. It is recommended that diodes are connected as
shown in the previous diagram (D₁, D₂).
Parallel Operation
Only 300- and 600-W models can be in parallel operation. Do not
operate any other models in parallel. The output of the models in par-
allel operation is a maximum of 80% of the rated output.
Set the parallel operation selector to PARALLEL if the Units are in
parallel operation and make sure that the thickness and the length of
all wires connected to the load are the same to ensure that the wires
will have no voltage drop differences.
Fan Replacement
The service life of the fan is approximately 50,000 hours (at 25°C).
The service life varies, however, depending on the ambient tempera-
ture or other surrounding environmental conditions such as dust. As
a preventive maintenance measure, replace the fan within two years
if it is used at an ambient temperature of 40°C.
Fans are available as replacements.
Model: S82Y-JFAN
Fan Set:
Fan (above), four M4 x 35 sems screws, instruction sheet, and pack-
ing case
Replace the fan as shown in the following illustration.
