Overload Protection
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 a set value
(105% of the rated output current for all models, 101% of the rated
output current for 90-W model), 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.
When using the 7.5-W single-output models within the input voltage
range between 90 and 110 VDC, the protection function will operate
at a current of 95% of the rated load current.
When using the 90-W model at an ambient temperature exceeding
25
°
C, the protection function will operate at a current of 92% of the
rated load current.

Note:
Do not short-circuit the output terminals of the S82K or
use the S82K with excessive output current for a long
time, otherwise the internal circuitry of the S82K may be
deteriorated or damaged.

Output Models
The +V output detects the total output power (+V output and -V out-
put) to trigger the short-circuit protection against overcurrent. This
protection varies depending on the -V output state. The -V output
independently triggers the short-circuit protection.
Overvoltage Protection
(S82K-24024T Models Only)
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, the protection function is triggered, shutting off the output volt-
age. If this occurs, reset the Power Supply by turning it off for 1 min-
ute min. and then turning it on again.
