■ Overload Protection
The Power supply is provided with an overload protection function
that protect the load and the power supply from possible damage by
over current. When the output current rises above between 105 to
130% (105 to 120% for the 40 A model) of the rated current, the pro-
tection function is triggered, decreasing the output voltage. When
output current falls within the rated range, the overload protection
function is automatically cleared.

5 A and 10 A models
If output voltage exceed the rated voltage more than 25% (50% at
maximum) by some reason, then an auxiliary feedback circuit will
operate limiting the output voltage for safety.
20 A and 40 A models
If output voltage exceed the rated voltage more than 25% (50% at
maximum) by some reason, then the output voltage will be turned
OFF automatically for safety. To restart the S8VT, turn OFF the input
voltage, wait few minutes, then apply the input power again.
