Miner Power Supply Repair Dedicated Digital Fast Capacitor Discharger The quick discharge voltage tester is specially designed for the discharge of capacitors (< 1000V) during maintenance, ensuring the safety of maintenance operations. It can be used for 8-1000V capacitor discharge without capacitance capacity limit. Discharge high DC current to a safe range to ensure no risk of electric shock and effectively avoid electric shock and short circuits. The voltmeter can display the voltage change during the discharge process, and when the voltmeter is turned off, the discharge is complete. It can also be used as a digital voltmeter (10 - 500V) to test DC/AC voltage. (When testing AC voltage, actual voltage = test voltage * 1.1; when testing DC voltage, actual voltage = test voltage.)
