(1) Low-voltage alarm: The buzzer sounds 2 audible with 1 Hz gap.

(2) Low voltage protection: The buzzer continuously sounds 3time alarm, with1 Hz gaps

(3) Low-voltage recovery: the low-voltage rise automatically restores the output, and

the buzzer sounds 3times alarm is cancelled.

(4) Overvoltage protection: The buzzer sounds 4 times, with 1 Hz gap.

(5) Overvoltage recovery: The voltage is reduced automatically to restore the output,

and the buzzer sounds 4times alarm is cancelled.

(6) thermal protection: 80 ° ± 5 °, when overheat protection buzzer sounds 5times alarm,

 with1Hz gap

(7) Overload protection: 10S automatic shutdown output for overload protection,

5S automatic recovery, automatic locking for three consecutive times

(8) Short circuit protection: Output short circuit protection 1S shutdown lock.
