75A SSR Solid State Relay is an electronic switching device, that switches on or off when a small external voltage is applied across its control terminals. Solid State Relay 75A consists of a sensor which response to an appropriate input (control signal). Solid State Relay 75A which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts.
Features:
- Special general circuit design for large current, high-quality circuit board
- Use copper terminals for big current, increase the safety of connection and use
- Use a pure aluminum base plate, with better performance and long life.
- Hign-end flame-retardant PV plastic, thermostability can up to 70-80 degrees.
- Protective cover for greater safety.
