- "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 4 3-phase circuits with one board configuration. It offers Modbus RTU 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 can be installed in a panel. Mechanical dimensions of the base board are 226 mm in width, 146 mm in height and 71 mm in depth."
