MikroElektronika's MIKROE-3169 PWR Meter click is a power measurement Click board, capable of measuring voltage and current through the load, connected to either an AC or DC power source. PWR Meter click uses the MCP39F511A, a very sophisticated monitoring IC from Microchip, with 16-bit processing core. It is used to calculate all the measurement parameters, returning values of multiple power parameters directly, over the UART interface, reducing the processing load on the host MCU. These parameters include active, reactive, and apparent power, current and voltage RMS, line frequency, and power factor.

PWR Meter click is based around the Microchip MCP39F511A, a power monitoring IC with on-chip 16-bit data processing and energy accumulation features. This IC is an advanced power monitoring IC, capable of calculating power characteristics, based on the measurements taken from the connected load and power supply. The IC can calculate active, reactive, and apparent power, current and voltage RMS, line frequency, and power factor. In addition, it features several useful functions, such as the programmable event reporting, with the onboard LED labeled as the EVENT. The Power Meter Click board is ideal for digital power monitoring/metering, power supplies, and IoT applications.
