A9MEM2000 modular power meter single phase iEM2000 – 230V – 40A

The Acti9 iEM2000 series power meter single phase offers an appealing selection of DIN rail-mounted energy meters suitable for sub-billing or partial meter applications. With this product family, building management may apportion energy costs and keep an eye on power use for individual units, office sectors, and floors. It has a mechanical display with seven digits that shows active energy. The meter will measure Active Energy with Class 1 active energy accuracy in accordance with IEC 62053-21 standard. With a supply voltage range of 184 to 276 VAC at 50Hz or 60Hz, it is appropriate for a 230VAC network. Direct connect current measurement in single phase and neutral setup up to 40A with only 32 samples per cycle.
