2. Protect Characteristics.

2.1 Output Over Voltage Protection

When the charger output voltage exceeds the maximum charging voltage, the charger enters the standby state protection. It will restore to normal working condition automatically after troubleshooting.

2.3  Output Over Current Protection

When the charger output current exceeds the maximum charging current, the charger enters the over current protection status. It will restore to normal working condition automatically after troubleshooting.

2.4  Short Circuit Protection

When the charger has short circuit at output, the charger enters short-circuit protection status. It will restore to normal working condition automatically after troubleshooting.

2.5   Reverse Polarity Protection

When the charger output positive negative pole and battery pack are connected in reverse, the internal relay of the charger is not sucked and there is no voltage current at the output terminal of the charger. After the correct connection, the charger can be charged normally.

2.6 Over-Temperature protection

When charger internal temperature exceed 75℃, it will be Into the over-temperature protection state and the cuts off output .When the temperature returns to 65℃, the charge is restored again.
