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 of use energy,
analyze power quality, display real-time waveform, record event and measure demand and is equipped with rich
input and output interfaces to monitor and control status of on-site equipments. Integrated RS-485 communication
interface can work together with a variety of intelligent power distribution systems and energy management systems,
sharing a wealth of monitoring data and power quality data.
Multi-function monitoring meter has a very good price level and can be used to directly replace the conventional
power transducer, measuring instruments, electric energy meter and relevant auxiliary unit. It has a wide range of
applications, such as energy management systems, power monitoring systems, industrial and mining enterprises,
public facilities, intelligent buildings, power distribution switchgear and other network systems.
