SSR-40VA is a voltage-regulating solid state relay controlled by external potentiometer. Users can connect an external variable resistor to adjust output AC voltage steplessly, realizing stepless power regulation of AC loads. Compared with mechanical contact relays, it features faster response speed and stable continuous adjustment performance, commonly used for oven heating control, lamp dimming, small AC motor speed adjustment and other automation equipment.
