Capacitor Discharge Pen Kit | DIY Tweezer Build | 1000V MOS Transistor

This capacitor discharge pen kit builds into a tweezer style discharger for draining residual voltage from capacitors, using a 1000V MOS transistor, so it must never be used above 1000V. It arrives as a DIY kit (circuit board, two tweezer probe arms, two probe tips, two black sleeves and a clear board sleeve, with the build shown in the photos) and makes a one hand pen listed at 11 x 2 x 0.8 cm. A blue LED lights while high voltage is being discharged. Features and Benefits - 1000V MOS transistor - rated for discharge voltages up to 1000V, never above - Tweezer probe arms - one hand grips both capacitor terminals - Blue LED indicator - lights while high voltage is present and being discharged - Not polarity sensitive - either probe can go on either terminal - No capacitor type limit stated - larger capacitances simply take longer - Self-assembly kit - a practical build for apprentices and training benches Applications - Switch power supply maintenance and electronic product overhaul - Circuit board fault finding and production testing - Electronics DIY, hardware experiments and apprentice training - Refurbishing second-hand electronic devices Note: Disconnect the power first, never exceed 1000V, and do not touch the circuitry or exposed metal during discharge. Avoid long continuous discharges so the pen can shed heat. Check the finished pen is assembled correctly and confirm zero volts with a meter before handling.
