AMC16-DETT Multi-circuit DC Energy Meter used in Base Sation

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 measure6 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.

FAQ

Q：The measurement of the metering module is inaccurate.

A：Check input whether the polarity and direction of the input voltage and current wiring are correct;Whether the direction of the primary current of the Hall sensor is correct; Whether the output signal of the Hall sensor matches the input signal required by the module; Check whether the output negative pole of the voltage output Hall sensor is connected to the module GND.

Q：Communication is abnormal.

A：Check communication whether the communication cable is normal; check whether the communication terminals A and B are staggered; check whether the address of the module is set correctly and whether the communication baud rate is set correctly; if the communication of multiple modules is not normal, first try whether the single-machine communication is normal.

Q：The metering module cannot bedisplayed normally.

A：Check whether it is caused by insufficient load capacity due to the built-in power supply to the hall sensor. Change the external switching power supply to power the hall.
