The iEM3250 energy meter is an attractive offering for a three-phase DIN rail mounted energy meter with LCD display. Additional local signalling includes a green LED power-on indicator, a flashing yellow LED for accuracy check and communication indicators. This meter can be used in billing and partial billing applications. The meter offers the following accuracy classes: Active energy: Class 0.5S according to IEC 62053-22 and according to IEC 61557-12. The meter measures active and reactive power, active and reactive energy, voltage and current. Designed for 50Hz or 60Hz networks, the supply voltage can vary from 100 to 277VAC or 173 to 480VAC. The rated current flows through a 1A or 5A current transformer to be measured in this meter and supports single phase and neutral, three phase and three phase and neutral configurations. Communication protocol is Modbus with screw terminal support. No secondary communication ports. Certifications include EAC, CE and UL. Product dimensions are as follows: width 90mm, depth 69mm, height 95mm and product weight 260g. Compatible with energy management software to take advantage of the digital energy supply offered by the Internet of Things (IoT).
