TVS – Varistors, MOVs

Transient Voltage Suppression (TVS) devices are electrical components designed to protect electronic circuits from damages caused by electrical pulses such as spikes or surges. There are two main categories of TVS devices: varistors and MOVs.

Varistors

Varistors, also known as metal oxide varistors (MOVs), are nonlinear, bi-directional components used for both overvoltage and undervoltage protection. Varistors are made up of metal oxide material with a high resistance to maintain a normal, steady state signal. When a voltage spike or surge occurs, however, the resistance of the material dramatically decreases, allowing current to pass through it to the circuit, thus protecting the component from electrical damage.Varistors are typically rated up to 1,200 volts and can be found in sizes ranging from 0.1 inch to one inch. They have a wide range of applications, including in motor control and power line protection.

MOVs

MOVs, or Metal Oxide Varistors, are surge protective devices designed to protect electronic devices from electrical spikes or surges. They are also bi-directional, allowing them to provide protection against both overvoltage and undervoltage conditions. MOVs are typically rated up to 21,000 volts and can be found in sizes ranging from 1/2 inch to one inch. They are commonly used in lightning protection systems and adjustable AC power supplies, as well as in motors, appliances, and communication systems.

2322 574 11703 Application Field and Working Principle

The 2322 574 11703 is a type of metal oxide varistor (MOV) designed for AC (alternating current) and DC (direct current) electrical applications. It has a rated voltage of 21,000 volts and a rated current of 11 amps. The working principle of MOVs is based on the material\'s nonlinear electrical behavior. Under normal operating conditions, the material has excellent insulation properties, allowing it to provide a steady-state voltage across the device. However, when exposed to a voltage spike or surge, the material\'s resistance decreases, allowing current to flow through it, thus protecting the component from electrical damage.Additionally, MOVs are useful for dealing with a variety of electrical disturbances, such as lightning, spikes, surges, and brownouts. They can also help to reduce the risk of voltage spikes due to inductive loads.

Conclusion

TVS components, such as varistors and MOVs, are essential for protecting electronic components from electrical damage. They can be used in a variety of applications, such as motor control, power line protection, lightning protection systems, and adjustable AC power supplies. The 2322 574 11703 is a type of MOV designed for both AC and DC applications, and it is rated at 21,000 volts and 11 amps. The MOVs working principle is based on the materials nonlinear electrical behavior, allowing it to reduce the impact of voltage spikes, surges, brownouts, and inductive loads.
