It can quickly discharge the residual power of capacitors generated by various electronic products (such as switching power supplies, digital cameras, mobile phones, etc.) during production, testing and maintenance protecting operators from and product damage. The pen-shaped design and portable size convenient to carry and use daily. This capacitor discharge pen supports 1200UF capacitor discharge, which can quickly discharge the residual power of high-voltage capacitors, but cannot be used for battery discharge. The discharge pen can automatically and intelligently identify the discharge time, without distinguishing electrodes, and the discharge is constant and spark-free., Manufacturer: Ounfhtrttk
