General
Acrel Wireless Three Phase Energy Meter is mainly used to meter
three phases of active energy on low voltage networks. This
wireless energy meter boasts advantages including compact size,
high precision, rich features. According to different requirements.
There are many communications functions like RS485 communication,
2G, NB, 4G, WiFi adding the new current sampling mode using an
external transformer. It can be flexibly installed in the
distribution box to achieve sub-item electric energy metering,
operation and maintenance supervision or power monitoring
requirements for different regions and different loads.
