Overview
Base station dedicated DC energy meter AMC16-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.

DIMENSION
INSTALLATION AND WIRINGS
Note: arrow direction should be the same with current direction marked on the sensor .
1. input voltage should not be higher than 120% of product’s rated input voltage, must install
1A fuse at the voltage input terminal.
2. Current input should use external diverter or hall sensor.
3. To ensure the accuracy,the DC meter should used together with Acrel hall sensors, the wiring length between sensors to meters should <3m.
4. Advise use three core shielded wires as communication connection wires. Each core >0.5mm² connect A,B, Connect shielding layer to earth, and keep communication line away from strong electric cable or other strong electric field environment during wiring
5. The hall sensor opening locking screw must be tightened to ensure the closed-loop tightness of the sensor
