SG4 series

• This relay is designed to proportionally vary the switching point on a sinusoidal mains supply via an isolated analogue control signal thereby varying the RMS voltage at the terminals of the load.
• Applications : light dimmer, heating regulation, single phase variable speed control (vibrating feeders,etc).
• Model with LED and RC and VDR network.
• These products should be mounted on heatsink in order to reach nominal current
• No external power supply required.
