1. Overheat protection:

   When the internal temperature of the charger exceeds 80 ℃, the current of the charger automatically decreases. When the temperature exceeds 85 ℃, the charger shuts down for protection. When the temperature drops, charging automatically resumes.

2. Short circuit protection:

    When the output is short circuited, the charger automatically turns off the output. After troubleshooting, reconnecting the battery can restore charging.

3. Reverse connection protection:

   When the battery is connected in reverse, the internal circuit of the charger will automatically disconnect from the battery, and if not charged, it will not damage the charger.

4. Input undervoltage and overvoltage protection:

   When the input voltage is below 90V or above 264V, the charger protection shuts down and automatically resumes operation after the voltage is normal.

5. Full automatic shutdown

   When the battery is fully charged, the charger will automatically stop charging to prevent overcharging of the battery.
