This solid state relay is great for controlling large power hungry mains devices. They can be activated by a 3V to 32V DC input and can switch from 24V to 380V AC. The massive 40A rating makes them ideal for using with large devices but a heatsink may be required for use at full capacity. They can be connected directly to our Power Pulse Modulator circuits for times, on/off control or dimming.
