Protection Requirement

Output short protection: No voltage output of charger without load, red light flashing, fault removal can be recovered.

Over current protection: Shut off and red light flashing when output current over 24A.

0 V charging: Battery locking protection. Output 43.2 V to charge and activate the battery within 5 seconds.

Reverse polarity Protection : Output off, red light flashing, fault removal can be recovered.

No-load protection: Less than 36 V safe voltage output , After connecting the battery, it will automatically identify and output the normal voltage.

High voltage protection: Turn off the output voltage when the output battery voltage is greater than 50 V.

Fully charged protection: When the charging time exceeds 20+/-2 hours, the set value will auto turn off the output voltage.

over-temperature Protection : When the temperature exceeds 7-℃+/-3℃, output shuts off, red light flashes, fan turns. the power supply will return to normal after the temperature down to 60℃.

Charge protection with full change battery: After the battery is fully charged, it is necessary to charge another battery, pull out the DC plug for an interval of ≥ 1.5 s  before plugging in for charging

Precharge protection function: 21.6 V-27.5 V, constant current is 4 A; Charging voltage to 27.5 V above, constant current 20 A charging
