SSR-25 DD 25A DC-to-DC Solid State Relay FOTEK
High-capacity SSR-25 DD single-phase DC-to-DC Solid State Relay designed for fast, high-current contactless switching of direct current loads in industrial automation, battery management systems, solar arrays, and high-power DC motor controls. Driven by a 3–32V DC control input, it reliably switches DC operating loads from 5V to 200V DC at up to 25 Amps continuous current. Featuring optical isolation between the input and output terminals, ultra-fast response times, and a solid-state design with no moving parts, it delivers spark-free, silent performance and long operational life under heavy-duty DC loads.
