RD002001-0713, Current Sensing Power Switch SCR Reference Design with ZAURA Control

Description

• RD002001-0713, Reference Design integrates ZAURA RF 868-MHz Wireless Module onto a Current-Sensing Power Switch SCR designed to showcase the features and performance of an AC switch based on an optically-isolated switch (CPC1966) which utilizes dual power SCR outputs, with an AC voltage/current 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 installations. 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. However, the Base Power Board cannot control the load, because the source of the pulses required to perform this operation is generated by the Z8F2480 MCU on the RF Module
