SSR-25 AA 25A Solid State Relay FOTEK
Heavy-duty SSR-25 AA single-phase Solid State Relay (SSR) engineered for high-current contactless AC load switching using an AC signal input. Controlled by an 80–250V AC control voltage, it smoothly switches AC output loads ranging from 24V to 380V AC up to 25 Amps continuous current. Designed with optical isolation between the control and output circuits, zero-cross switching technology to suppress voltage surges, and a solid-state structure with no mechanical parts, it ensures spark-free, silent operation and long operational life in industrial heating, HVAC controls, automated machinery, and power control panels.
