SSR-25 DA-H 25A High-Voltage Solid State Relay FOTEK
Industrial heavy-duty SSR-25 DA-H high-voltage single-phase Solid State Relay (SSR) engineered for high-current and high-AC-voltage load switching in demanding industrial heating, process control, commercial HVAC, and three-phase motor drive applications. Controlled by a low-voltage 3–32V DC input signal, it safely switches high-voltage AC loads from 90V up to 480V AC at up to 25 Amps continuous current. Featuring optical isolation between control and load terminals, zero-cross switching technology to suppress surge currents and electrical noise, and a solid-state structure with no moving parts, it delivers spark-free, silent operation and exceptional reliability in 380V/440V power networks.
