Essential Info

The EE Systems Group EE778PRM ePower Solid State AC Control Relay Module is ideal for most AC power control applications. This state-of-the-art relay has rugged back-to-back SCR outputs and is rated for use on AC lines up to 530Vrms. This relay can withstand over voltage transients up to 1200Vpk. The low control current needed for DC control is achieved by unique active current limited input, which can reduce power supply requirements, particularly where multiple relays are used. DC control random turn-on relays are phase controllable. The standard AC control voltage is 90-280VAC; Current rating from 12 - 65 amps. This relay is encapsulated in thermal conductive epoxy.

The Relay Module is ideal for situations of controlling lighting, AC units, Boilers, and many other situations. For example, a business couple use a 12V trigger from their security system to turn off the A/C and heating in the building when arming the system. Also, a home owner can connect 12V motion sensor to turn off a set of lights.
