Description: CRD5463PM Power Monitor
Reference Design and Software
The CRD5463PM demonstrates the CS5463 power measurement IC. It has an integrated AC-DC power supply,voltage and current sensors, and isolated UART/USB interface. Working with the GUI software, it provides accurate real-time measurements of line voltage, load current, line
frequency, active power, reactive power, pparent power,power factor, and temperature.
The CRD5463PM includes two power cords, a USB cable, and a plug adaptor. When used with a PC, the CRD5463PM immediately becomes a high-precision power meter. The UART interface communication protocol, GUI, and MCU software source codes are also available from Cirrus Logic.
The CRD5463PM is a useful design reference and evaluationtool for customers to develop power metering/monitoring systems that use the CS5463 IC. Platform: |
