Output short circuit protection

(Yes)

After a fault is rectified, the system automatically resets.

Over temperature protection

 

(Yes)105℃

When the internal temperature of the coil is105℃ per 30 sec., the output power is reduced by 3.125% from the existing base to 0. When the temperature is less than105℃ per 60 sec., the output power is increased by 3.125% from the existing base to the rated power.

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 20S.

Charging timeout

 

(Yes)

Charge continuously for more than 4 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.
