Protection characteristics
Over-voltage protection-When the output voltage of the charger exceeds the maximum charging voltage, the charger enters the standby protection state and can automatically return to the normal working state after troubleshooting.
Over-current protection-When the output current of the charger exceeds the maximum charging current, the charger enters the over-current protection state, and the output current will be limited to the maximum charging current value, and the output voltage will be reduced to close to 0V. Automatic return to normal working state after troubleshooting.
Short-circuit protection-When the output of the charger is short circuit, the charger enters the short circuit protection state, the output current is constant as the maximum charging current value, the output voltage is close to 0V, and automatically returns the normal working state after troubleshooting.
Anti-connection protection-When the correct output negative electrode of the charger is inversely connected with the positive and negative electrode of the battery pack, the relay does not engage, and there is no voltage current at the output terminal of the charger, and the charger can charge normally after correct wiring.
