TVS - Varistors, MOVs - ROV14H471K-S Application Field and Working Principle

A TVS (transient voltage suppressor), also known as a varistor or a MOV (metal oxide varistor), is a specialized application component designed to provide surge protection for sensitive electronics. It works by controlling the electrical current that runs through an electronic circuit or device, and it is a cheap and reliable way of protecting circuits. One such device is the ROV14H471K-S, which can protect both AC and DC powered circuits from any short-term spikes or transients which could otherwise cause irreparable damage.The ROV14H471K-S is a radial leaded Varistor with a breakdown voltage of 475VAC and a clamping voltage of 780VAC. It is designed to absorb and regulate the voltage from a large range of inputs, from an AC power supply to low DC voltages. The device is rated for a surge current of up to 35A, and is designed using metal oxide construction, which allows it to react quickly, and also has an ultra-low leakage current capability.When it is used in an AC application such as power supplies, the ROV14H471K-S works by limiting the voltage that passes through to a predetermined level. When the voltage that is passing through the circuit surpasses the Varistor’s rated breakdown voltage, it will activate a clamping action which then limits the current flowing through the circuit. This prevents any damage to the terminal the Varistor is attached to, as well as any downstream components that may be attached to it.On the other hand, when used in electric motor systems, the ROV14H471K-S can also provide protection against the transient voltages which are created when the motor is connected to the power supply. Because the motors tend to draw high inrush current when they are started, the Varistor works to absorb and neutralize the excess voltage, which helps to protect the motor and any downstream components.The Varistor also has several other applications, such as being used as a surge protector for sensitive electronic equipment. By protecting against transient voltages, the device helps to ensure that sensitive electronics remain operational even in the event of a power surge. It can even be used in battery charging systems, as it can reduce the amount of internal resistance in the charging system and enable the battery to charge faster.Overall, the ROV14H471K-S is an extremely versatile Varistor with a wide range of applications. Its ability to protect against transient and overvoltage spikes mean it is an extremely reliable and cost-effective way of protecting sensitive electronics. Varistors are designed to react quickly to overvoltages, meaning that they can absorb the voltage before it can cause any damage to the circuit. This in turn makes them a perfect choice for protecting sensitive electronics from power surges. Another advantage of using a Varistor is its low leakage current capability, which means it does not cause electricity to be wasted when it is inactive. Finally, the metal oxide construction used in the ROV14H471K-S ensures that it is able to react quickly to overvoltages, and can be used in both AC and DC applications. By being able to absorb and regulate the voltage from a wide range of inputs, the ROV14H471K-S can provide reliable and cost-effective protection against power surges and transient voltages.
