Protection

Short Circuit

Hiccup mode, recovers automatically after fault condition is removed.

Over Load

105%~120% Hiccup mode, recovers automatically after fault condition is removed.

Over temperature

Ambient temperature over 55℃±5℃ , output reduce to 50%;

Ambient temperature over 60℃±5℃, output off;

When the temperature is reduced to 45℃±5℃ the output returns to 100%.
