Three Phase Solid State Relay (TSR) 25DA

The Three Phase Solid State Relay (TSR) 25DA is a high-capacity reactive power compensation unit specifically designed to regulate voltage levels, improve power factor, and maintain grid stability under dynamic load conditions. By integrating advanced thyristor-controlled switching technology, it provides rapid and precise control of inductive reactive power, making it suitable for heavy industrial applications, utilities, and smart grid systems.

Engineered with robust thyristor valves, low-loss iron-core reactors, and reliable cooling mechanisms, the TSR 25DA delivers long-term performance with minimal maintenance. Its fast-response switching capability (in milliseconds) allows seamless operation during sudden load fluctuations, while the optimized design minimizes harmonic distortion and ensures compliance with international power quality standards. The device supports modular configurations, enabling flexible installation and scalability in both medium- and high-voltage networks.

The 25DA model is rated for high efficiency and continuous duty, with key specifications including rated current handling capacity, high dielectric strength, low total harmonic distortion (THD), and protection features against over-voltage, over-current, and thermal stress. This makes the Three Phase Solid State Relay 25DA an ideal choice for industries requiring reliable power factor correction, such as steel plants, refineries, data centers, and transmission utilities, ensuring energy efficiency, reduced losses, and enhanced operational safety.
