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.

functionsBasic function

Monitor device system time, total voltage, output total current, 

power, energy, each channel voltage, current, power, energy; LED 

indicator display;485 communication

Metering function

Start current: under rated voltage, when the load current value of 

the meter doesn’t exceed 1% of the max. current, the meter 


Shunt running current: when there is no current in the current 

circuit of the meter, and 85%-125%of the rated voltage is applied 

on the voltage circuit, the calculator shall not have more than 

one digital change

Alarm functionDC voltage output low alarm,DC voltage output high alarm,one 

power down alarm, module voltage loss alarm, metering branch 

error alarm, internal program error alarm, clock error alarm, 

memory failure alarm, AC input power failure alarm

Timing functionsupport broadcast timing, could remote timing to the meter

through RS485 communication.

CommunicationSingle channel RS485, baudrate 9600bps, can be set to 1200BPS, 

2400bps, 4800bps.

Communication protocol: standard or custmized

Hall sensor power supplyPower supply output:+12V/100Ma, -12V/50mA
Clock accuracy≤0.5S/d(23℃), ≤1S/d(-20℃-60℃),
Auxiliary power supplyVoltage range-40V~-60VDC
Power consumptionWhole device≤2W( no hall power supply output)





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
