RS485 Lora 3 phase energy monitoring power meter with CTs piercing connect AEW100-D20X
Acrel Co.,Ltd. has experience of over decades in various kind of energy meters.Among them,AEW din rail electric energy meter is with mini size,high accuracy,and it is easy to install. The AEW series have also got CE.
AEW 100 wireless measurement module is mainly used for metering three phase active energy on low voltage network. There are functions like RS485 communication and wireless communication on 470MHz in order to help customers check, get and
manage the value of energy consumption. This kind of production has the advantage of higher accuracy, more compact and easy installing. It can be installed in distribution box flexibly, achieving the different demand of measurement and statistics of
distribution on different areas and different loading.
