an inexpensive yet super-fast acting device designed to create a short circuit across the line if the voltage across its terminals exceeds the breakdown point of the MOV
A semiconductor device that acts as a safety valve to absorb high voltage transients harmlessly, thereby protecting the SCRs and preventing false firing.
A type of lightning arrester which offers high resistance to low voltages, and low resistance to high voltages. Placing a MOV from a conductor to ground causes high voltage spikes to short-circuit to ground.
(MOV) A device whose impedance decreases dramatically when subjected to voltages greater than the rated clamping voltage. It is typically placed in parallel with the input and/or output of a switching device to effectively clamp transient voltage spikes to a certain level.
(MOV) A MOV is a voltage sensitive breakdown device which is commonly used to limit overvoltage conditions (electrical surges) on power and data lines. When the applied voltage exceeds the breakdown point, the resistance of the MOV decreases from a very high level (thousands of ohms) to a very low level (a few ohms). The actual resistance of the device is a function of the rate of applied voltage and current.
A solid-state surge suppression component that can handle large amounts of current and react within nanoseconds.
