S82K
J OVERLOAD PROTECTION
The Power Supply has 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 of most 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: To avoid damage to the unit or deterioration of the internal
circuitry, do not short-circuit the output terminals of the
S82K or use the S82K with excessive output current for a
long time.

When Using Output Models
The +V output detects the total output power (+V output and
–V output) 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.

J OVERVOLTAGE PROTECTION
(S82K-24024T MODELS ONLY)
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, the protection function is triggered, shutting off
the output voltage. If this occurs, reset the Power Supply by
turning it off for 1 minute min. and then turning it on again.
