A metal oxide varistor, or MOV, is an electronic component that protects restaurant equipment from voltage surges in a power line, such as from lightning strikes. Simple and inexpensive, the MOV absorbs the energy in a surge, preventing it from damaging other devices in a circuit. A transient voltage suppressor or TVS is a general classification of an array of devices that are designed to react to sudden or momentary overvoltage conditions. One such common device used for this purpose is known as the transient voltage suppression diode designed to protect electronic devices against overvoltage. Another design alternative applies a family of products that are known as metaloxide varistors MOV that protect electronic circuits and electrical equipment. Voltage suppressors act a circuit breakers. Voltage suppressors can also be non integrated electronic noise suppressors. Features. 275V MOV Transient Suppressor.
