Equipment Overview:

The AMC16-DETT base station DC energy metering module is mainly designed for base stations with shared needs and switch power supplies without user specific energy metering functions

Designed. The instrument can measure the direct current of six circuits, with a built-in power supply for the Hall sensor. At the same time, it can achieve zero drift calibration through the upper computer software. It has functions such as telemetry, remote signaling, remote adjustment, real-time power measurement, abnormal power supply quality alarm, information storage and processing, and information exchange. The DC energy metering module can measure the DC electricity consumption of three operators, provide detailed data basis for energy-saving improvement of base stations, and provide reliable sub metering solutions for DC distribution equipment.

The module has an industrial standard RS485 communication interface and adopts the YD/T1363.3-2014 protocol, which complies with the relevant technical requirements of Q/ZTT2205-2017 "Technical Requirements for Base Station DC Energy Metering Modules" of China Tower Corporation.

The specific functions are as follows:

Monitoring equipment system time, total voltage, total output current, total power, total electrical energy, branch voltage, branch current, branch power, and branch electrical energy; LED indicator light display; RS485 communication

Measurement: Starting current: At rated voltage, when the load current value of the measurement module does not exceed 1% of the current, the module starts with a creep current. When there is no current in the current circuit of the measurement module and the voltage applied to the voltage circuit is 85% to 125% of the rated value, the module calculator should not have more than one digital change;

● Alarm: DC voltage output low alarm, DC voltage output high alarm, power outage alarm, module voltage loss alarm, metering branch error alarm, internal program error alarm, clock error alarm, memory failure alarm, AC input power outage alarm;

● Timing: Supports broadcasting timing and can remotely calibrate the metering module through RS485 communication interface;

Storage: It has the function of storing historical energy data and historical alarm information, with a memory of 2MB.
