2. Protect Characteristics
8.1 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 condition.
8.2 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.
8.3 Short Circuit Protection
When the charger has short circuit at output, the charger enters short-circuit protection status. Troubleshooting automatically return to normal working condition.
8.4 Reverse Polarity Protection
If charger DC output terminal connect to battery reverse, fuse on the output side would be fuse, output circuit would be cut off. Replace the fuse, and then connect to battery correctly, charger would resume working.
