AMC16-DETT Din-rail Multi-channel DC Energy Meter
General
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. The module can measure the DC power consumption of multiple circuits separately, providing detail datas for base station.
