What is MOV in electronics component?

A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode. This type is commonly known as the metal-oxide varistor (MOV).

What is MOV electrical component?

What is the function of MOV?

An MOV is a voltage dependent device which has an electrical behavior similar to back to back zener diodes. changes from a near open circuit to a very low value, thus clamping the transient voltage to a safe level. pulse is absorbed by the Varistor, thereby protecting vulnerable circuit components.

Which is the maximum working voltage of a MOV?

MOV Specifications Maximum working voltage is the maximum steady-state, DC voltage. Varistor voltage Maximum clamping voltage is obtained when a certain pulse current is applied to the component to obtain a maximum peak voltage. Surge current Surge shift refers to the variation in voltage after a surge current is given.

When do you get maximum clamping voltage?

Maximum clamping voltage is obtained when a certain pulse current is applied to the component to obtain a maximum peak voltage. Surge shift refers to the variation in voltage after a surge current is given.

What is the difference between surge and clamping voltage?

Clamping voltage: It is the voltage at which the MOV starts to conduct and dissipate the surge current. Surge Current: It is the maximum peak current that can be given to the device without causing any device damage; it is mostly expressed in ‘current for a given time’.

What is the maximum allowable voltage for a varistor?
