High Quality Multifunctional Monitoring Meters

High-performance multi-function monitoring meter can measure real-time power parameters, harmonics,forward and reverse active/reactive energy and time of use energy with high precision, can timing read time ofuse energy, analyze power quality, display real-time waveform, record event and measure demand and isequipped with rich input and output interfaces to monitor and control status of on-site equipments. IntegratedRS-485 communication interface can work together with a variety of intelligent power distribution systems andenergy management systems, sharing a wealthof monitoring data and power quality data.

Multi-function monitoring meter has a very good price level and can be used to directly replace theconventional power transducer, measuring instruments, electric energy meter and relevant auxiliary unit. It hasa wide range of applications, such as energy management systems, power monitoring systems, industrial andmining enterprises, public facilities, intelligent buildings, power distribution switchgear and other networksystems.
