Built-in Protection Functions

Overload Protection

Overload protection operates at approximately 105%–150% of rated output power. The protection shuts down the output voltage when the overload condition is triggered. Remove the abnormal load and re-power the unit to recover.

Overvoltage Protection

Overvoltage protection is provided for each output model, with protection levels ranging from 5.75–6.75V for the S-150-5 up to 55.2–64.8V for the S-150-48. The output shuts down when protection is triggered; re-power the unit after the fault condition is removed.

Short Circuit Protection

Built-in short-circuit protection helps protect the power supply during abnormal output conditions. According to the official specification note, if the power supply is short-circuited under no load, it automatically recovers when the short circuit is removed.
