As a trusted resistor supplier, WishPower offers a wide range of zinc oxide varistors designed for surge protection and voltage spike suppression. These varistors are essential for protecting electronic and electrical equipment from overvoltage damage in power systems, consumer electronics, industrial controllers, and more.
A zinc oxide varistor stays in high resistance mode under normal voltage. When a transient overvoltage occurs, it switches to a low-resistance state, allowing surge energy to dissipate quickly. Known for fast response and high energy absorption, these devices are key components in both low- and medium-voltage surge protection systems.
