High Power Solid State Relay Control Unit
Solid State Relay Control Unit SSR-CU provides possibility to control devices which use a standard electrical outlet. Low voltage microcontroller or other low voltage equipment can be used as a control device. The SSR-CU uses high-power solid-state relay and provides fully galvanically isolation of low voltage control signal from high voltage.
