TVS - Varistors, MOVs are broadly used in modern electronics, especially in the safety and protection of low-voltage applications. Among them, V480LA7P is a reliable and commonly used series of High-Energy Varistors manufactured by CITEL, which is particularly suitable for providing surge protection of the electrical equipment and systems.

The V480LA7P series is designed by using zinc oxide ceramic material for the sensitive element which is combined with an epoxy resin package which has excellent corrosion and mechanical stability. Under normal operating conditions the V480LA7P components provide a high-impedance path to the incoming transient discharge, thus absorbing the transient energy and providing the protection to the system. One of the main advantages of V480LA7P series is its excellent durability as it can endure over 12000 shots with AC Impulse Voltage of 6/12 kV.

Moreover, V480LA7P series provide variety of protection levels. Apart from 3 screws clamp type, other models and variations include two options: axial type and radial type. It is suitable for mounting on either voltage line or ground line for multiple applications.

The working principle of V480LA7P is simple as it consists of a variety of common electrical components. Inside, a varistor is essentially a series of interconnected components formed in an array. When no pulse voltage is applied, it behaves like an open-circuit. When certain overvoltage is applied, the varistor’s component react, thus setting up a clamping mechanism. This mechanism clamps the overvoltage to a safe level and thus provides protection for the systems from excessive surge.

Some of the main applications of V480LA7P series varistors are lightning protection of AC power, high-voltage peak protection of TVs and PCs, radio frequency power line protection, and many more. Moreover, it is compliant with IEC 60664-1 international standard and meets UL1449 VPR standard.

Overall, V480LA7P series of High-Energy Varistors made by CITEL exhibits excellent characteristics such as effectiveness,durability and versatility, and provides reliable protection to electrical equipment. Its simple working mechanism combined with various options and compatibility with international standard makes V480LA7P series one of the best in its area of application.
