SSR-25 VA 25A Voltage Regulator Solid State Relay FOTEK
Industrial-grade SSR-25 VA heavy-duty single-phase Solid State Voltage Regulator (SSVR) designed for proportional AC power tuning and variable load regulation. Driven by an external 470KΩ to 560KΩ (2W) potentiometer, it provides smooth, stepless phase-angle adjustment for AC output loads ranging from 24V to 380V AC up to 25 Amps continuous current. Designed for high-capacity applications such as industrial electric furnace heating control, heavy resistance loads, light dimming arrays, and AC motor/fan speed adjustments. Built with optical isolation between control and load terminals, flame-retardant housing, and a solid-state architecture with no moving parts for spark-free, silent, and long-term reliable operation.
