AMC16-DETT

Base station dedicated DC energy meter AMC16(L)-DETT is specially designed for base stations where have sharing requirements, and switch power supply is without the function of sub-user metering. The meter could measure 6 circuits DC energy, and supply working current to the matched hall sensors. Meanwhile, it can realize zero drift calibration by upper computer software. have the functions of telemetering,teleindication,teleadjusting, metering at real time, energy quality abnormal alarm, data storage and processing, data interaction. This meter can measure DC power consumption of three operators, providing detail datas for base station.

Project: American Tower Project and Kenya Telecom Tower Power Monitoring Project.
