1 AC surge current(cold start)AC

 Atcoldstart,25℃,DC output ratedloading;264 Vac input conditions, when input power is applied to the powersupply ,peak inrush current  limited to30A, Repetitive ON/OFF cycling of the input voltage will not damage the charger.

2 Output Short Circiut Protection

Shorting of output will not cause power supplyto damage or any safety hazard. The power supply resume normal operation aftershort is removed.

3 HI-POT

 Primary-to-Secondary: VOLTAGE 3000VAC TIME60SOR VOLTAGE 3800VAC TIME 3S. CUT OFF CURRENT 5mA.

4 Lightning test
