The R820 Series silicon control rectifiers provide modulation of electric loads using industry-standard proportional controls from thermostats and building systems. It incorporates a compact control board mounted to a multifin, black, anodized heat sink with an exceptionally high heat dissipation rate. The integral heat sink minimizes installation time and wiring costs. Models are available in single- or three-phase and can control loads up to 600V and 75A (single-phase only). According to the manufacturer, the rectifiers are a great solution for retrofit projects involving electric heaters because of the relatively low cost and easy selection process. The integrated self-setting thermostatic protection increases safety, the multiinput control signal maximizes application and system flexibility, and the LED confirms proper operation.
