Protect Characteristics
Output Over-Voltage Protection
When the charger output voltage exceeds the maximum charging voltage, the charger enters the standby state protection. Troubleshooting can be automatically restored to normal working conditions.
Output Over Current Protection
When the charger output current exceeds the maximum charging current, the charger enters the over-current protection status. Troubleshooting automatically restored to normal working condition.
Short Circuit Protection
When the charger has a short circuit at the output, the charger enters short-circuit protection status. Troubleshooting automatically returns to normal working conditions.
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.
Over-Temperature protection
When the charger’s internal temperature exceeds 75℃, it will be Into the over-temperature protection state and the cutoff output. When the temperature returns to 65℃, the charge is restored again.
