PVR-20D221K Overview
Pan Overseas Zinc Oxide Varistors PVR - ZINC OXIDE VARISTORS Introduction Zinc Oxide Varistor is a non-linear resistance device, whose voltage and current relationship vary according to the Law of Powers. When high Voltage transients or surges produced by induced lightning, switching or electrical noise, the varistor will switch from the rest stage to the protective stage. It is extremely high resistance value will...
