Description
The MCP3914 Smart Power Strip (v2) Reference Design is a fully functional power monitor capable of measuring up to 6 device loads simultaneously while reporting data to an LCD display or wirelessly connected web-based UI via an on-board Wifi Module . The Power Strip offers universal socket support for China, Europe and US geographies. The system metrology firmware calculates the real-time values of the RMS Current, RMS Voltage, Frequency, and Active Power consumption for each channel.
Features
RMS Current, RMS Voltage, Active Power and Line Frequency MeasurementsOversampling Ratio up to 4096Power Monitoring Accuracy capable of 0.1% error over a 10,000:1 dynamic range94.5 dB SINAD, -107 dBc THD (up to 35th Harmonic), 112 dBFS SFDRLow-Drift 1.2V Internal Voltage Reference: 9 ppm/°C typical40-lead 5x5 mm UQFN PackageExtended Temperature Range -40°C to +125°
Typical applications
- Smart Power Strip
