SSR-50 DA-H 50A High-Voltage Solid State Relay FOTEK
Industrial extra heavy-duty SSR-50 DA-H high-voltage single-phase Solid State Relay (SSR) engineered for high-current and high-AC-voltage load switching in demanding industrial heating, commercial HVAC, plastic extrusion machinery, and heavy motor control applications. Operated by a low-voltage 3–32V DC logic control signal, it smoothly and safely switches high-voltage AC operating loads ranging from 90V up to 480V AC at up to 50 Amps continuous current. Featuring optocoupler isolation between control logic and output load terminals, zero-cross switching technology to eliminate surge currents and electrical interference, and a fully solid-state construction, it delivers spark-free, silent switching and long service life across 380V/440V industrial AC power lines.
