Product Data Sheet

The Acti9 iEM3000 series energy meters provide a versatile selection of three-phase energy meters that are mounted on DIN rails and come with an LCD display. The meters feature additional local indicators such as a green LED for power-on status, a flashing yellow LED for accuracy checks, an overload alarm, and communication status indicators. These meters are suitable for sub-billing applications and support up to four tariff schedules.

The meter is designed to meet the accuracy standard like- Active Energy Class 0.5S as per IEC 62053-22, Active Energy Class C according to EN 50470-3, and Active Energy Class 0.5S as per IEC 61557-12. It can measure Active and Reactive Power, Energy, Voltage, and Current, with four-quadrant energy measurement. The meter is made for both 50Hz and 60Hz networks. With a supply voltage range of 100 to 277VAC or 173 to 480VAC. It measures rated current using a 1A or 5A transformer and supports Single Phase and Neutral, Three Phase, and Three Phase with Neutral configurations.

The communication protocol used is Modbus, with screw terminal connections. Additionally, the meter offers one programmable digital input and one programmable digital output. Which can be set as a pulsed output. It has certifications including EAC, CE, UL, and NMI. The product measures 3.54 inches (90 mm) in width, 2.72 inches (69 mm) in depth, and 3.74 inches (95 mm) in height, weighing 9.17 oz (260 g). It works with power management software for integration into IoT-enabled digital power systems.
