Overvoltage Protection |
For some reason the power supply fails to control itself, the build-in over voltage protection circuit will auto recovery the outputs to prevent damaging external circuits, the trigger point is around 120%~150% of output voltage |

Short Circuit Protection |
Fully protected against output overload and short circuits. Automatic recovery upon overload condition |
