CDB5480U

1.7 Standalone Meter Application
The CDB5480U evaluation board provides a standalone power meter using the CS5480, MCU, and LCD.
The user can enable the power meter by connecting the sensors to the analog inputs, providing power to
the board, and resetting the MCU by pressing the RESET switch. Refer to “Typical Sensor Connections”
on page 11 for details on the sensor connections and “Power Supply Selection” on page 10 the details on
supply options.
The user should not use the GUI to connect the CDB5480U board. If the GUI is connected to the
CDB5480U board the standalone power meter function is disabled and the LCD on the CDB5480U will
read "Cirrus Logic CS5480 Eval GUI". To re-enable the standalone power meter feature, close the GUI
software. The standalone power meter feature will initially show the voltage channels’ RMS register
values:
V1rms = N.NNNNN and V2rms = N.NNNNN.
By clicking the onboard switch S2, the standalone power meter will display the following measurement
results:
1. RMS Voltage
2. RMS Current
3. Average Active Power
4. Average Reactive Power
5. Average Apparent Power
6. Power Factors
7. Total Active Power
8. Total Reactive Power
9. Total Apparent Power
10. Fundamental Frequency
11. CS5480 die Temperature
