Zinc oxide varistor

Color: Blue

Verification: CE

Product description

The varistor is a voltage limiting type protection device. Using 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 varistor of the latter circuit. Parameters are: varistor voltage, current capacity, junction capacitance, response time, etc.

working principle

The varistor utilizes the nonlinear characteristic 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 protecting the latter circuit. .

Product specifications

Use attention

1. When the surge pulse is applied to the varistor with a short intermittent repetition, the average power at this time should be lower than the maximum static power.

2. If the thermistor is connected between the live part of the equipment and the metal casing, necessary measures must be taken to prevent accidents caused by electric shock.

3. When using the varistor, avoid direct sunlight. Do not work in the open air or outdoors.

4. The varistor should avoid working under the conditions of high temperature and high humidity such as wind, rain and water vapor, and should also avoid working under dust, salt and harmful gases. Protection box should be used if necessary
