YEKMLCO FDQ1 Digital Capacitor Discharger – Quick Discharge & Voltage Tester for Electricians

Overview

Meet the YEKMLCO FDQ1 Digital Capacitor Discharger, a compact handheld tool designed for safe offline capacitor discharge during maintenance tasks. It handles capacitors from 10 to 1000 volts in a range of electronics, including switching power supplies, digital cameras, mobile devices, and TV power panels. It is not intended to discharge batteries.

Engineered for safety and reliability, the FDQ1 helps minimize risk by discharging capacitors to a safer range. A built‑in voltmeter provides a live readout of voltage changes during the process; when the display powers down, the discharge is complete. The discharge is non-polar and spark-free, operated under a constant current for steady performance.

Key Benefits at a Glance

• Offline discharge for high-voltage capacitors (10–1000V) during routine maintenance.
• Live voltage monitoring to track progress and confirm when to stop.
• No polarity in discharge and no sparking, reducing handling risks.
• Short, clear demonstrations of quick discharge times for common voltages (≈5 seconds at 400V).

How It Works

Usage is simple and purpose-built for technicians. The device self-tests when connected to power, then the probes clip to the capacitor (non‑polar) to begin discharge. The unit displays voltage changes during the process, and once the voltage falls to around 6V, the display may turn off. After a brief pause, discharge can continue to below 2V to reach a safe endpoint.

• Self-test: Short the probes to AC power; a display and audible cue confirm operation.
• Discharge: Attach probes to the capacitor (non-polar) and start the discharge; the screen reflects progress.
• Completion: Discharge continues until the voltage nears or drops below 2V for safe handling.

Safety Notes and Proper Use

• Discharge should be performed offline on high-voltage capacitors only; do not use as a general electronic load.
• Avoid discharging while charging and do not discharge electrostatic double-layer capacitors.
• The FDQ1 is designed to minimize risk of electric shock and short circuits during maintenance tasks.
