This reference design integrates a Z8F2480-based AC power monitor with Ziilog’s eZ80F91 Webserver Module to showcase the capability of an optically-isolated Z8F2480 MCU-based power monitor to measure ...

This AC Power Monitor continuously watches the AC power line voltage for both under-voltage and missing cycles. When it detects a total of 5 or 6 consecutive missing half-cycles (50mS, 50/60HZ), it ...

Building your own hardware to measure AC power isn’t a simple task. There’s a number of things to measure, including voltage, current, power, and power factor. The Atmel 90E24 is a single chip ...

Guest columnist Christopher Gobok, product marketing engineer at Linear Technology believes that accurate power supply voltage and current monitoring is crucial to conserving power and guaranteeing ...
