The Acti9 iEM3355 is an electronic energy meter for DIN rail mounting, with direct connection and a rated current of 125 A. Its type of measurement covers active and reactive energy, active and reactive power, current and voltage, and its metering type is active, reactive and apparent energy (signed, four quadrant). Active energy accuracy is Class 1 conforming to IEC 62053-21 and Class B conforming to EN 50470-3. Readings are shown on an LCD display, and the meter has a Modbus RTU communication port on an RS485 screw terminal block, one digital input and one digital output. Device applications are multi-tariff, sub billing and partial meter, for cost management billing and cost allocation on main incomers, sub feeders and panelboards in small, medium, large and multi-site buildings, data centres, healthcare and industry.
