The high-voltage capacitor discharge pen adopts a constant current discharge design and can be used for both AC and DC without distinguishing the positive and negative poles. The gold-plated extra-tip test pen is connected and can flexibly respond to the needs of occasions. During the normal discharge process, the green status indicator light be on. If the indicator light goes out, it indicates that the energy of the energy storage capacitor has been discharged below the safe energy. It is a practical tool for power supply maintenance and safe discharge of high-voltage energy storage capacitors. The pen tip can be removed, if thewire is broken in use, it is easy to The circuit design is reasonable, regardless of the positive and negative poles, the positive and negative polescanbe connectedfreely.Just to the two poles of the capacitor.
