Wireless Controlled Power SSR for AC Power with a Remote Control

Zilog introuced its new ZAURA(tm) Reference Design to expand its portfolio of digital wireless solutions that target the industry need for wireless connectivity in control, sensing, eliminate standby power consumption and for power metering applications.

This reference design integrates Zilog's ZAURA™ RF 868 MHz Wireless Module onto a Current-Sensing Power SSR. The product is designed, to showcase wireless control of an AC power SSR. The IXYS ICD power SSR is part number CPC1966, with an AC zero-crossing detection to minimize surge currents and sine wave distortions. This reference design can be used as a basis for developing systems that can control different power products.

On its own, without the ZAURA RF Wireless 868 MHz Module attached, this design's Base Power Board functions as a development board to provide current to power the Module and the switch. This Base Power Board, with the Module attached and controlled by a hand-held remote control device, enables RF communication to turn a load on and off. To demonstrate RF control, a hand-held ZAURA RF remote control device is also included with this reference design. Documentation supplied with this reference design provides specifications and schematics, describes its software commands, and also provides a procedure for quickly getting started with development.

The Current-Sensing Power Switch SSR can be used to develop a number of applications, including remote-operated commercial or architectural lighting, private lighting with remote control convenience features and remote-operated household or industrial equipment. This new RF platform helps to shorten the time-to-market scenario across a wide range of wireless power management applications. Customers can remotely control their connection to a power grid, or machines can control their grid connectivity automatically based on load conditions.
