Reference Design: Z8F2480 Power Monitor with eZ80F91 Webserver Reference Design (ZRD0027PLM0ZRD)

The Z8F2480 Power Monitor with eZ80F91 Webserver reference design integrates a Z8F2480-based AC power monitor with Zilog’s eZ80F91 Webserver Module to showcase the capability of an optically-isolated Z8F2480 MCU-based power monitor to measure AC input voltage, AC load current, voltage/current phase shift, the power factor of the load, and to communicate via a standard Ethernet interface and webserver.


The Z8F2480 MCU and the eZ80F91 Webserver Module are connected for easy mounting. The load is powered via a single-phase AC line with voltage in the range of 90 V to 240 V RMS at 50 Hz or 60 Hz. The Z8F2480 MCU-based power board provides current to a power load and provides optically-isolated I2C signals to communicate with the eZ80F91 Module.


This reference design can be used as a basis for developing systems that can control different power installations, including motors and lighting ballasts.


The Z8F2480 Power Monitor with eZ80F91 Webserver Reference Design ships with the following items:


  • Z8F2480 AC Monitor Power Board
  • eZ80F91 Webserver Module
  • 5 VDC power supply
