Capacitor Discharge Pen | Red and Green Dual LED | 1000V Max

This capacitor discharge pen drains residual charge from capacitors in power supplies and electronics, up to a maximum discharge voltage of 1000V. The red LED shows high voltage, the green LED takes over below about 42V, and when the green LED goes out the discharge is complete with about 6V left in the capacitor. The stated working range is AC 8 to 380V and DC 12 to 540V. Features and Benefits - Red and green dual LED - see at a glance whether the voltage is still high or already low. - 1000V MOSFET, board marked 1000V Max - a clear printed limit for power supply repair work. - Sprung probes with adjustable spacing - they flex instead of crushing and set to the pin pitch. - No set capacitance limit - larger capacitors simply take longer to drain. - Compact 133 x 15mm board - one handed use, with a hanging hole in the handle end. - Warnings printed on the back - no touching exposed metal, and watch the heat on continuous discharge. Applications - Switch power supply repair: drain the bulk and filter capacitors before you work on the board. - Electronics repair benches: release residual voltage before desoldering or testing. - Production and test lines: clear stored charge from boards between test steps. Note: Disconnect the power first. Do not touch the circuit or exposed metal while discharging, and do not hold the pen on for long periods. About 6V remains when the green LED goes out, so confirm zero volts with a meter.
