■ Overload Protection
10- to 300-W Models
The Power Supply is provided with an overload protection function
that protects 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, automatically
decreasing the output voltage. When the output current falls within
the rated range, the overload protection function is automatically
cleared.
The values shown in the above diagrams are for reference only.

600-W Models
If an excessive current flows for 5 s or more, the output will be turned
OFF and simultaneously the protection-ON alarm indicator will be lit.
To reset the S82J, turn OFF the power, leave the S82J for at least
three minutes, and then turn it ON again.

■ Overvoltage Protection
100-W (5-, 24-V Output) Models
Consider the possibility of an overvoltage and design the system so
that the load will not be subjected to an excessive voltage even if the
feedback circuit in the Power Supply fails. When an excessive
voltage that is approximately 120% of the rated voltage or more is
output, the output voltage is shut OFF, preventing damage to the load
due to overvoltage. Reset the input power by turning it OFF for at
least one minute and then turning it back ON again.
The values shown in the above diagram are for reference only.
300- and 600-W Models
When an excessive voltage that is approximately 120% of the rated
voltage or more is output, the output voltage will be turned OFF and
simultaneously the protection-ON alarm indicator will be lit. Reset the
input power by turning it OFF for at least three minutes (90 seconds
for 300-W models) and then turning it back ON again.
■ Overheat Protection Function
600-W Models Only
If the internal temperature rises excessively as a result of fan failure
or any other reason, the overheat protection circuit will be triggered
to protect the internal parts and simultaneously the protection-ON
alarm indicator will be lit. Reset the input power by turning it OFF for
at least three minutes and then turning it back ON again.
