Capacitor Discharge Pen V1.0 – AC/DC 540V Tool for Crypto Miner Repairs & Electronics

Capacitor Discharge Pen V1.0 | AC/DC 540V Tool for Crypto Miner Repairs & Electronics

Upgrade your crypto-mining repair toolkit with the Capacitor Discharge Pen V1.0 — a high-voltage, universal AC/DC discharge tool designed for safety and efficiency. Engineered with a rectifier bridge input, this pen effortlessly discharges capacitors up to 680µF / 450V without polarity checks, making it ideal for ASIC miner repairs, PCB maintenance, and electronics troubleshooting where high-voltage bulk capacitors hold dangerous residual charge after the unit is unplugged.

The constant-current discharge approach prevents the sparking and pad damage common when bridging a charged capacitor with a screwdriver — the pen drains the charge cleanly and predictably while a built-in LED indicator gives visual confirmation of the discharge cycle in under four seconds. Anti-static heat-shrink insulation along the probe shaft and a plum-blossom probe tip protect both the operator and the surrounding circuitry during the operation.

Constant-Current Discharge Pen for 680µF / 450V Capacitors

• Constant-current discharge — prevents sparking with stable current flow across the discharge cycle.
• 540V DC / 380V AC range — handles high-voltage capacitors in mining rigs, TVs, appliances, and industrial PSUs.
• LED discharge indicator — visual confirmation with under-4-second discharge time.
• Anti-static heat-shrink insulation — safe for sensitive components nearby.
• Plum-blossom probe tip — scratch-free testing on delicate circuits and through conformal coatings.

Why a Discharge Pen Is Essential for ASIC PSU Repair

Bulk capacitors in ASIC miner PSUs and Bitcoin-miner power supplies routinely hold 200-400V for minutes after the unit is unplugged. Bridging those caps with a metal tool — a screwdriver, pliers, the probes of a multimeter — produces a violent arc that can damage the cap, the surrounding board, and the operator. The Capacitor Discharge Pen V1.0 is the right tool for the job: drain the charge through a current-limited resistive path, get the LED indicator confirming the cap is safe, and proceed with the repair. This is bench-safety hardware, not a luxury.
