Senva EMX : Revenue Grade True RMS Energy Meter, RS-485 2-Wire BACnet & Modbus, Pulse kWh, KVAR, kVA, OLED Screen, Buy American Act Compliant, 7 Year Limited Warranty
The Senva EMX Advanced Energy Meter is designed to be user-friendly and easy to install. This True RMS energy meter features a vibrant color OLED screen and a data-rich user interface. Setting up the EMX Advanced is as simple as connecting it to L1, L2, and L3. With pulse and RS485 outputs, it can seamlessly integrate with any metering or control device, making it incredibly versatile.
The EMX Advanced is perfect for a wide range of applications. It excels in energy management and performance contracting, allowing you to monitor and optimize energy usage in commercial and industrial facilities. It's also ideal for monitoring energy consumption for commercial tenants and implementing activity-based costing. You can efficiently manage power distribution and usage with real-time power monitoring and load shedding capabilities.
One of the standout features of the EMX Advanced is its intelligent meter technology. With the new Configuration App and Senva Sync, the setup process is streamlined, saving you time and effort. This energy meter is self-powered and can accommodate 1 to 3 phase voltage ranging from 90V to 600V. It functions as three independent voltage/current power meters in one, allowing you to mix and match CT sizes for multiple loads. The EMX Advanced also supports various pulse inputs and outputs, enabling you to track energy usage and other power metrics precisely.
