When the output voltage exceeds the set voltage of 2.5 v and lasts for 20 seconds, the power supply is shut down automatically.

Output short circuit protection

(Yes)

Self-recovery within 30 seconds, after 30 seconds automatically shut down, need to re-start the boot command will be restarted

Over temperature protection

 

(Yes)

The power supply automatically detects the temperature of the device. When the temperature is very high, the power supply will automatically reduce the amount. The power supply will resume after the temperature is lowered.

Battery reverse connection protection

(Yes)

The battery is connected inversely and the power supply does not turn on

Communication interruption

(Yes)

The charger will automatically shut down if no master command is received within 120S.

Charging timeout

 

(Yes)

Charge continuously for more than 10 hours, power off.

NTC fault

(Yes)

NTC fault

1) When the temperature is less than -30(NTC open circuit ), to be shutdown lasts more than 5 min.

2) Temperature >125(NTC short circuit ),shutdown in 15sec.
