Timers MOV 14D Metal Oxide Varistor Multipurpose For New Energy

Non-Polarity MOV-14D Metal Oxide Varistor Low Leakage Current Strong Surge Withstand Capacity

What is a varistor used for? The biggest feature of the varistor is that when the voltage applied to it is lower than its threshold "UN", the current flowing through it is extremely small, which is equivalent to a closed valve. When the voltage exceeds UN, its resistance The value becomes smaller, so that the current flowing through it increases sharply and the influence on other circuits does not change much, thereby reducing the influence of overvoltage on subsequent sensitive circuits. Utilizing this function, it is possible to suppress the abnormal overvoltage that often occurs in the circuit and protect the circuit from damage caused by overvoltage.
For example: Zinc oxide varistors are used in the power supply circuit of our home color TV. The varistor voltage of the varistor used here is 470V. When the maximum transient surge voltage (non-effective value) exceeds 470V, the voltage The sensitive resistor is to reflect its clamping characteristics, which can pull down the excessive voltage and make the subsequent circuit work in a safe range.

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.
6. Current capacity (maximum inrush current)
