The PS04LTVA2 is an industrial-grade plug-in transient voltage surge suppressor (TVS) designed for applications in which multi-stage surge protection is critical. This particular device is composed of a series of filters along with a combination of varistors, MOVs, and ceramic protection modules and is designed to protect against overvoltage, overcurrent, and short-circuit events. Additionally, the PS04LTVA2 is designed with a built-in circuit breaker for additional protection against these transient surges.

TVS devices, particularly those such as the PS04LTVA2, are designed to create a shield for equipment from different types of overvoltage transients. These transients could include power inrush, power cross-talk, power coupling, and power-line spikes. TVS devices, such as the PS04LTVA2, use two or more components—usually MOVs or varistors—to divert these transient surges away from the equipment, effectively protecting it from potential damage.

Varistors, also known as voltage-dependent resistors (VDRs), are primarily used in TVS devices for the purpose of suppressing or diverting the harmful electrical transients caused by electrical power surges. Varistors can absorb a large amount of energy during these transient surges, making them ideal protectors for sensitive electrical components. The PS04LTVA2 features proprietary, high-performance NTC ceramic varistors for superior performance in this application.

MOVs, or metal oxide varistors, are another type of surge-protection device. These MOVs are designed to “clamp” the voltage at a specific level before any surge can reach the protected equipment. The PS04LTVA2 features proprietary high-performance non-MOVs silicon varistors for enhanced performance in this application.

Ceramic protection modules, or CPMs, are also used in the PS04LTVA2. These CPMs are composed of multiple layers of insulating and conductive materials, which work together to reduce the surge energy by obstructing or absorbing it before it can reach the equipment. Additionally, the layers are designed to provide a high degree of insulation, making them well-suited to the demands of the application.

In order to provide the best protection for equipment against these types of transients, the PS04LTVA2 utilizes various protection methods within its series of filters and ceramic protection modules. It features a combination of MOVs, NTC ceramic varistors, and silicon varistors. By combining these components, the device is able to divert the harmful surges away from the protected equipment and thus provide superior protection. Additionally, the PS04LTVA2 is designed with a built-in circuit breaker for additional protection against these transients.

The combination of varistors, MOVs, and ceramic protection modules in the PS04LTVA2 allows it to effectively protect against common power surges. Its unique combination of filters, along with the built in circuit breaker, make the PS04LTVA2 an ideal solution for industrial surge protection needs.
