Overload Protection; Overvoltage Protection - Omron S8EA Series Manual

S8EA

Overload Protection

The overload protection circuit will automatically reduce the output
voltage for short circuits and overcurrents to protect the Power Supply
from short-circuit currents and overcurrents.
When the output current falls within the rated range, the overload
protection function is automatically cleared.

Overvoltage Protection

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 130% of the rated
voltage or higher is output, the output voltage is shut OFF, preventing
damage to the load due to overvoltage.
To reset the protection, turn OFF the input power for three minutes or
longer and then turn it back ON.
