AMC16-DETT Base Station DC Energy Meter for 5G Tower 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 tele-metering, tele-indication, tele-adjusting, metering in real-time, energy quality abnormal alarm, data storage, and processing, data interaction.

Functions
|
Basic function | Monitor device system time, total voltage, total current, power, energy, each channel voltage, current, power, energy; LED display,RS485 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 starts. 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 function | DC under-voltage, DC over-voltage, one power down, module voltage loss, metering branch error, internal program error, clock error, memory failure, AC input power failure | |
| AHKC-EKA (50A/5V) | AHKC-EKB (100A/5V) | AHKC-K (200A/5V) |
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 be displayed 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.
