With a wide operating supply range, the ACM20 Series functions with a universal AC input making it ideal for worldwide power monitoring applications. Consuming low power of less than 1/4W at 120VAC, it can monitor single or split-phase AC mains and is self-powered with a 2-wire operation. Boasting rugged construction with its one-piece polycarbonate housing, the ACM20 offers a large, bright red LED display that is easily readable from as far as 15 feet or 5 meters. Metallic fasteners offers secure installation and as mentioned on the previous slide, the ACM20 fits existing ACA-20PC and competitors’ ‘Power Meter’ cutouts. With precision electronics, the ACM20 energy metering IC provides accuracies to ±1% for voltage and current. Using a low-power, micro-controller based design, this multifunction AC power meter includes a low component-count design which ensures high reliability. Quartz crystal time-base is also included for precision frequency measurement. And finally, the ACM20 is competitively priced.
