Three Phase Solid State Relay (TSR) 50DA

The Three Phase Solid State Relay (TSR) 50DA is an advanced reactive power compensation unit developed for power systems requiring fast, precise, and reliable voltage and power factor regulation. Equipped with state-of-the-art thyristor switching technology, it provides rapid response to system voltage fluctuations while minimizing switching transients. This makes it ideal for industrial plants, steel mills, refineries, and utilities where dynamic load changes are frequent.

Engineered with high-quality reactors and low-loss thyristor modules, the TSR 50DA ensures smooth operation under varying load conditions. It effectively reduces the risk of voltage instability, suppresses harmonic distortion, and prevents system resonance. The design also incorporates efficient thermal management, high dielectric strength insulation, and advanced protection mechanisms against overcurrent, short circuits, and voltage surges.

Key specifications include a rated capacity of 50 kVAR (adjustable as per system requirement), voltage range compatibility from 3.3kV to 11kV, fast switching time in the range of 10–20 ms, and long operational life with minimal maintenance. The Three Phase Solid State Relay 50DA is compact, durable, and designed for easy integration into existing capacitor banks or Static VAR Compensators (SVCs). Its robust performance ensures optimal power quality, improved equipment lifespan, and significant energy efficiency benefits for demanding electrical environments.
