The HYFK series composite switch represents a revolutionary breakthrough in the field of capacitive switching contactors. This innovative device effectively combines the advantages of both technologies by employing a parallel thyristor switch and a magnetically protected switch. The HYFK series utilizes the zero-crossing switching characteristics of the thyristor during both the turn-on and turn-off phases, while simultaneously achieving zero power consumption of the magnetically protected switch under normal conduction conditions, providing a unique solution for low-voltage reactive power compensation applications.

The HYFK series capacitive switching contactors feature a built-in microprocessor and intelligent software design for precise control of capacitor switching operations. This intelligent control mechanism ensures efficient switching operation and minimizes the risk of arcing and inrush currents that could damage electrical components. Zero-crossing switching technology guarantees that no arcing occurs during operation, a common defect in traditional contactors. This gives the HYFK series contactors a fast response time, making them ideal for applications requiring reliable and rapid switching.

A major highlight of the HYFK series capacitive switching contactor is their near-zero on-resistance. This characteristic not only eliminates harmonic generation but also ensures zero switching inrush current. Therefore, no current-limiting reactor is needed, significantly reducing the overall cost of the control cabinet. This raises an important question: how much cost can a company save by switching to more efficient capacitive contactors like the HYFK series? The answer lies in the reduction of installation and operating costs, making it a wise and economical choice for many companies.

The HYFK series composite switches are not only economical and efficient, but also consume extremely low power, less than 1% of that of traditional contactors. This low power consumption not only contributes to energy conservation but also means that the switches generate very little heat, allowing them to be installed in sealed enclosures without concerns about overheating. This feature is particularly advantageous in environments where space is limited or heat dissipation is critical.

The HYFK series capacitive switching contactors are designed for long life, exhibiting a lower failure rate and significantly extended service life compared to traditional thyristors and contactors. Their simple structure and ease of installation further enhance their appeal, making them an ideal choice for engineers and technicians. The HYFK series offers a wider operating temperature range, adapting to various environmental conditions and ensuring reliable operation in a wide range of applications. The HYFK series composite switches represent a significant advancement in capacitive switching contactors, perfectly combining efficiency, economy, and durability.
