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 (105% of the rated output current for
300-W
models), the protection function is triggered, decreasing the
output
voltage. When the output current falls within the rated range,
the
overload protection function is automatically 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 of
f 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 of
f the output voltage. If this occurs, reset the Power
Supply by turning it off for 1 minutes min. and then turning it on
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 of
f the input
voltage, leave the S82J for at least three min

utes,
and then apply the input voltage again.
