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 can be installed in distribution box flexibly, achieving the different demand of measurement and statistics of distribution on different areas and different loadings.
Note:
1. Choose W before choosing CG;
2. There is a mobile antenna lay outside can be chosen, and the length of wire is 2 meters.
