Information
The Acti9 iEM2100 series energy meters offer is a single-phase DIN rail-mounted energy meters fitted for basic metering. This product family can be used to monitor power consumption for each sector, unit or workshop and manage electrical installation for building management. It feature a 8-character LCD display and red LED indicator to display measured electrical parameters. Providing Class 1 active energy accuracy per IEC 62053-21 standard, the meter will measure Active and Reactive Power, Active and Reactive Energy, Voltage and Current. Suitable for a 230VAC network, with a supply voltage range of 96 to 276 VAC at 50Hz or 60Hz. Direct connect current measurement up to 63A with 32 samples per cycle only in a Single Phase and Neutral configuration. Communication protocol is Modbus RTU with 3 wire terminal support, no additional communication ports. Product dimensions are as follows: width 36 mm, depth 64 mm, height 90 mm and product weight 175 g. Compatible with power management software to take advantage of the IoT digital power installation.
