Multifunction Power Meter
Model：ZY-DPM25• Energy consumption sub-metering for floors, areas, and HVAC systems in commercial buildings
• Meter reading and billing for public facilities and sub-tenants in shopping malls
• Energy efficiency management for chillers and HVAC systems
The ZY-DPM25 Multifunction Power Meter is specifically designed for industrial and commercial power distribution systems. It provides simultaneous measurement of three-phase voltage, current, frequency, power, power factor, and energy, enabling users to monitor power quality and load status effectively.
Featuring RS-485 (Modbus RTU) and Ethernet (Modbus TCP) interfaces, the device supports seamless integration with SCADA, BMS, and EMS platforms. This connectivity facilitates remote data collection, real-time alerts, and trend analysis, making it ideal for sub-metering, power auditing, and energy-saving retrofits.
For enhanced application flexibility, an optional WiFi HaLow module is available for wireless data transmission in challenging wiring environments. The meter is certified by CE and FCC, ensuring long-term stability and reliable performance in demanding professional settings.
