XSSVR-W1 / W2 Phase-Angle Single-Phase AC Solid State Voltage Regulator Overview
The XSSVR-W1/W2 Series is a screw-mounted, horizontally installed single-phase solid state voltage regulator that uses phase-angle control via an external potentiometer to adjust output voltage precisely. W1 models support 5A to 40A loads, while W2 models handle high-power loads up to 200A. Compact in size and easy to install, these models are ideal for industrial heating, lighting dimming, and basic motor speed regulation.
