Protect 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 conditions automatically after troubleshooting.

Short Circuit Protection
When the charger has a short circuit at the output, the charger enters short-circuit protection status. It will restore to normal working conditions automatically after troubleshooting.

Over-Temperature protection
When the charger’s internal temperature exceeds 85, it will be Into the over-temperature protection state and the cuts off output, and the cooling fan stop working. When the temperature returns to 65, the charge is restored again
