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 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. 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; During the normal discharge process, the green status indicator light be on. If the indicator light out, it indicates that the of the storage capacitor has been discharged below the safe . It is a practical tool for power supply maintenance and safe discharge of high-voltage storage capacitors. Note: This version supports stable operation within DC 1000V/4700uF. If the circuit is complex and multiple storage capacitors are connected in parallel, the superimposed capacitance value needs to be estimated. Continuous discharge is not recommended., Weight: 0.16755131912 pounds, Manufacturer: ximie
