S82J

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% of the
rated output current (105% to 160% of the rated output current for 50
(24 V)-W and 100 (24 V)-W models), the protection function is trig-
gered, decreasing the output voltage. When the output current falls
within the rated range, the overload protection function is automati-
cally cleared.

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 dam-
aged or broken.

Overvoltage Protection

100 (5, 24 V)-W Models
The Power Supply is provided with an overvoltage protection func-
tion that protects the load and the Power Supply from possible dam-
age by overvoltage. When the output voltage rises above a set val-
ue (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.
Rated output
voltage
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.

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 simul-
taneously a protection-ON alarm indicator will be lit. To reset the
S82J, turn off the input voltage, leave the S82J for at least three min-
utes, and then apply the input voltage again.
