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 various occasions. During the normal discharge process, the green status indicator light will 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. 1200V high-power IGBT tube with voltage resistance, rapid discharge with constant current regardless of forward and reverse, and no ignition; Support discharge within 5000UF The discharge current is 80-100mA, and the 4700uF large capacitor can be discharged without pressure at one time (320V 1000uF is discharged in about 6 seconds, 320V 2000uF is discharged in about 10 seconds), and so on; Note: This version supports stable operation within DC 1000V/4700uF. If the circuit is complex and multiple energy storage capacitors are connected in parallel, the superimposed capacitance value needs to be estimated. Continuous discharge is not recommended.<br><br>Material: plastic+metal colour: As shown<br><br>Package Contents: 1 x Capacitor Discharge Pen<br><br>Only the above package content, other products are not included.
