Note: Fusing time can be customized according to user requirements.
After repeatedly switching K1 on/off 100 times (2S on, 2S off), the test resistor should not be open-circuited.
Note: 1. Capacitor C selection based on customer requirements; default C=10uF if not specified. 2. Resistor R value selected based on usage circuit, converted to internal resistance. Resistor power rating is 20W, power factor 0.8. For resistors under 10W, generally use 20W, 5.1K(5%).
