I Overload Protection
10- to 300-W Models
The Power Supply is provided with an overload protection function
that protects the load and the power supply from possible damage by
overcurrent. When the output current rises above 105% to 160% of
the rated output current, the protection function is triggered, decreas-
ing the output voltage. When the output current falls within the rated
range, the overload protection function is automatically cleared.
10- to 100 (24 V)-W Models 100 (5, 12, 15 V)-W, 150-W,
and 300-W Models
I Overvoltage Protection
100 (5, 24 V)-W Models
The Power Supply is provided with an overvoltage protection function
that protects the load and the Power Supply from possible damage
by overvoltage. When the output voltage rises above a set value
(120% of the rated output voltage), the protection function is trig-
gered, shutting off the output voltage. If this occurs, reset the Power
Supply by turning it off for 1 minutes min. and then turning it on
again.

Note: 1. If the S82J is connected to a load with a built-in DC-DC con-
verter, the overload protection function may be triggered at
startup, and consequently the S82J may not operate.
2. Do not continue using the S82J with the output terminals
short-circuited or the overcurrent condition continued, oth-
erwise the internal elements of the S82J may be damaged
or broken.
3. In actual operation, the output voltage may not fall to 0 V
when the overload protection function is triggered. Even
with short-circuits on the load side, the drop in voltage will
vary depending on factors such as the impedance in the
load line.
4. The overload protection function is activated at 105% of the
rated output current for 300-W models.
600-W Models
If an excessive current flows for 5 s or more, the output will be turned
off and simultaneously protection-ON alarm indicator will be lit. To
reset the S82J, turn off the input voltage, leave the S82J for at least
three minutes, and then apply the input voltage again.
Note: Do not continue using the S82J with the output terminals short-
circuited or the overcurrent condition continued, otherwise the
internal elements of the S82J may be damaged or broken.

300- and 600-W Models
If a voltage that is 120% of the rated output voltage or above is out-
put, the output voltage will be turned off and simultaneously protec-
tion-ON alarm indicator will be lit. To reset the S82J, turn off the input
voltage, leave the S82J for at least three minutes if it is a 600-W
model or at least 90 seconds if it is a 300-W model, and then apply
the input voltage again.
I Overheat Protection Function
600-W Model Only
If the internal temperature of the S82J rises excessively as a result of
fan failure or any other reason, the overheat protection circuit will be
triggered to protect the internal elements of the S82J and simulta-
neously a protection-ON alarm indicator will be lit. To reset the S82J,
turn off the input voltage, leave the S82J for at least three minutes,
and then apply the input voltage again.
