Protection Function

1. Over Temperature Protection

When the internal temperature of the charger exceeds 80℃, the charging current will reduce automatically. When it exceeds 85℃, the charger shut down for protection. When the temperature drop, the charger antomatically resumes to charge.

2. Short Circuit Protection

When the output short circuit, the charger will automatically shut down the output. After troubleshooting, the battery can be reconnected to resume charging.

3. Battery Reverse Polarity Protection

When the battery is reverse connected, the internal circuit of the charger will automatically disconnect from the battery, without charging, without damaging the charger.

4. Low-voltage & Over-voltage Protection

If the input voltage is lower than 90V or higher than 264V, the charger will shut down protectively and automatically resume working with the voltage is normal again.

5. Full Automatic Shutdown

Automatically shut down after full charge.
