Protection Features

Input over voltage protection

Ø When input voltage is 295±5Vac：The warning light is on, the output is normal

Ø When input voltage is 310±10Vac：output off. And input disconnected from the grid, it

can automatically recover after the voltage is normal. Input recovery point hysteresis>10V

Input over-voltage recovery

Input voltage<290Vac，automatic recovery

Input under-voltage protection

Input voltage<80±5Vac output off

Input under-voltage recovery

Input voltage>80~90VAC, automatic recovery

Output over-voltage protection

The output overvoltage protection range is 36.5VDC~38.5VDC. After the module enters the lock protection state after overvoltage protection, the AC power supply needs to be disconnected first, and then powered on again, the power supply can work again.

Output under-voltage

protection

The range is 15VDC~19VDC, when it is lower than the under-voltage alarm value, it will output normally and report an alarm prompt

Output short-circuit protection

It can be short-circuited for a long time, and it can be automatically restored after the

short-circuit disappears.

Overtemperature protection

With over temperature protection
