The high-voltage capacitor discharge pen features a constant current discharge design and is compatible with both AC and DC circuits without polarity distinction. The gold-plated test tip ensures reliable contact and adaptability for various applications. During normal discharge, the green status indicator light remains illuminated. When the light turns off, the energy stored in the capacitor has been reduced to a safe level. This tool is suitable for power supply maintenance and safe discharge of high-voltage capacitors. The pen tip is removable, allowing for easy replacement if the wire becomes damaged. The circuit design supports connection to either polarity—simply connect to both terminals of the capacitor. Color: Black & Red Material: Plastic + Metal Package Contents: 2 x Capacitor Discharge Pen Note: Color may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
