The Acti 9 iEM series from Schneider Electric includes a range of DIN rail-mounted energy meters designed to measure and monitor electrical energy consumption in various settings. These meters offer solutions for both basic and advanced energy monitoring needs, making them suitable for residential, commercial, and industrial applications.

Key Features:

1. Energy Measurement: The iEM series meters measure various parameters, including active energy (kWh), reactive energy (kvarh), and other electrical parameters depending on the model.
2. DIN Rail Mounting: Designed for easy installation on standard DIN rails, these meters are compact and fit well in electrical distribution panels.
3. LCD Display: Equipped with a clear LCD display for real-time data visualization, making it easy to read and monitor energy consumption directly from the device.
4. Communication Capabilities: Depending on the model, meters can offer communication options like Modbus, BACnet, and pulse outputs for integration with energy management systems (EMS) or building management systems (BMS).
5. Accuracy: High accuracy levels (typically Class 1 or Class 0.5) ensure precise energy measurement, crucial for cost allocation and energy efficiency initiatives.
6. Multi-Tariff Options: Some models support multi-tariff configurations, allowing for energy consumption tracking based on different time-of-use rates.
7. User-Friendly Interface: Intuitive interface and easy setup process make these meters user-friendly for installers and end-users alike.
8. Compliance: Meets international standards such as IEC 62053-21/22 for energy measurement.
