Reverse output protection |
No output, no damage |

Output short circuit protec- tion |
Can cause long-term sh- ort circuits |
|
If a short circuit is detected before the high- voltage startup, the high-voltage output will not start. After the fault is resolved, it will resume normal operation. During charging, if a short circuit occurs, the output will be turned off. |
|

Overheat protect- ion |
The output current de- creases by 5% for every 1℃ increase in temper- ature, starting at 65℃. The over-temperature protection turns off the output when the temp- erature exceeds 85℃, and the charger resumes output when the temp- erature drops back to 75 ℃ or below. |
