Application Scenarios
The EM719028's versatility and communication capabilities make it an ideal choice for a wide range of sub-metering and energy management
Commercial and Tenant Sub-metering: Accurately monitor and bill energy usage for individual tenants in office buildings, shopping malls, and multi-unit residential complexes. It integrates seamlessly into Building Management Systems (BMS) for centralized monitoring.
Industrial Energy Management: Track the power consumption of heavy machinery, production lines, and motor control centers (MCCs). This helps in allocating energy costs to different departments and identifying opportunities for efficiency improvements.
Data Center Power Monitoring: Essential for monitoring energy consumption in Power Distribution Units (PDUs) and for tracking the Power Usage Effectiveness (PUE) of data centers and server rooms.
Renewable Energy Systems: Monitor the performance and energy production of three-phase solar PV installations, wind turbines, and other renewable energy sources to ensure they are operating at peak efficiency.
Energy Audits and Monitoring: A key tool for energy consultants and facility managers to perform detailed energy audits, verify savings from retrofits, and continuously monitor critical energy loads.
Electric Vehicle(EV) Charging Stations: Ideal for measuring the energy delivered by three-phase commercial EV charging infrastructure, enabling accurate billing and effective load management.
