TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are the two most popular surge protection devices (SPDs). Varistors are also referred to as transient voltage suppressors because they respond quickly to sudden changes in voltage. These devices work by providing an effective, low-cost method of protecting sensitive electronic components and systems from electrical surges or voltage spikes. The V39CH8S application field and working principle are discussed here.

V39CH8S Application Field

The V39CH8S is a surge protective device specifically designed for use in industrial applications. It is a unipolar device with a maximum operating voltage of 250VAC and a maximum steady state voltage of 310VAC. It is capable of withstanding up to 8 kV of surge protection. This makes it suitable for protection of electronic systems from overvoltage and transients in industrial and commercial applications, particularly in high voltage fixed and portable equipment.

It is ideal for use in telecommunications, automation, control systems, motors, transformers, pumps, and medical equipment. It is also well suited for use in electrical power system, automotive and other transportation applications. Additionally, it can be used in hazardous and explosive environments such as electric motors, oil and gas pipelines, and aircraft.

V39CH8S Working Principle

The V39CH8S is a unipolar device that combines metal oxide varistors (MOVs) and voltage suppression capacitors. A MOV is designed to switch quickly on and off when a voltage spike reaches a certain threshold. It works by providing an alternative path for the surge current to flow, thus diverting it away from the system. The internal voltage suppression capacitor acts to store the energy of the overvoltage and release it in a more manageable manner.

The V39CH8S is designed for use in industrial and commercial applications where the overvoltage is likely to be of short duration. The MOV provides fast response and reduces the peak voltage, while the capacitors act to limit the current and dissipate the energy in a more controlled manner. This ensures a safe and effective protection of systems from electrical surges, spikes and transients.

Conclusion

The V39CH8S is a unipolar surge suppressor designed for use in industrial and commercial settings. It combines a MOV with voltage suppression capacitors to provide a fast and effective surge protection solution. It is capable of withstanding up to 8 kV of surge protection, making it suitable for use in a wide range of applications. It is therefore an ideal choice for implementing surge protection in sensitive electronic systems.
