Protection

Over load

110-180%rated output power ,protection type:hiccup mode,recovers automatcally after

fault  condition removed

Over Current

When the over current occurs(Average output current 130-150%), the power supply

will automatically switch to self-protection status, when condition removed,then switch back to normal .

Over voltage

0ver voltage set : 120-140% rated voltage

Short circuit

 When short condition occurs, independent PTC fuse will open the circuit,when

condition removed , PTC fuse will automatically back to close .
