  • "This multi-circuit power meter is part of the PowerLogic EM4900 Series. This device is a multi-circuit power meters that make it easy to add many revenue-grade metering points. Without having to purchase, mount, wire and commission individual energy meters. This version measures current, voltage, power and energy consumption of up to 14 3-phase circuits with one board configuration. It also offers Ethernet and serial communications. Measurement accuracy is plus or minus 1 % with LVCT0xxxx0S split core, or plus or minus 0.5 % with LVCT2xxxx0S split core. The printed board is installed in a sturdy metal enclosure. Mechanical dimensions of the main unit are 253 mm in width, 353 mm in height and 71 mm in depth."
