High Performance MOV Metal Oxide Varistor Wide Working Voltage Range
The varistor is a voltage limiting protection device. Utilizing the nonlinear characteristics of the varistor, when an overvoltage occurs between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby realizing the protection of the subsequent circuit.
The main characteristics of varistors are wide operating voltage range (6~3000V, divided into several grades), fast response to overvoltage pulses (nanosecond level), strong impact current resistance (100~2000a), and small leakage current (micro An level), small temperature coefficient of resistance, high performance, low price, small size. It is an ideal protection component, which can form overvoltage protection circuit, muffler circuit, spark suppression circuit, and absorption circuit. When the overvoltage pulse is superimposed on the power network, after connecting the rheostat, the overvoltage peak waveform is flattened and limited within a certain range. When using inductance and capacitance to open or close the load circuit, the switch tip pulse appears in the DC waveform, and the varistor can absorb the counter electromotive force in the circuit, thus effectively protecting the switch circuit from damage

Application
1. Varistor voltage: refers to the voltage value across the varistor at a specified temperature and DC (generally 1mA or 0.1mA). Recorded as V1mA or V0.1mAo
2. Maximum continuous voltage: refers to the maximum effective value of sinusoidal AC voltage or the maximum DC voltage value that can be continuously applied to both ends of the varistor for a long time under the specified ambient temperature
3. Limiting voltage: refers to the maximum peak voltage at both ends of the varistor when a specified surge current (8,20μs) passes through it.
4. Rated power: refers to the maximum average impact power that can be applied to the varistor under the specified ambient temperature.
5. Maximum energy: the maximum impact energy that can be applied to the varistor under the condition that the varistor voltage does not change more than ±10% and the impulse current waveform is 10, 1000μs or 2ms.
