Charge Curve
Protection Characteristics
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.
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.
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.
Environmental
