J OVERLOAD PROTECTION
The S8E3 is provided with an overload protection function
that protects the load and the S8E3 from possible damage
by overcurrent. The following graph shows the overload
detection and reset operation of the S8E3.

J OVERVOLTAGE PROTECTION
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 (120% of the rated output voltage),
the protection function is triggered, shutting off all of the
output voltage. If this occurs, reset the Power Supply by
turning it off for 1 minute min. and then turning it on again.
