Laos Acrel DTSD1352-4S Digital Multi Circuits AC Energy Meter For Tower Base Station Energy Consumption Monitoring
Category:
Product Description
Overview
DTSD1352-4S series DIN-rail type multi-circuit power meter is mainly used for the full electric parameter measurement of multiple circuits, and can be connected to the current input of 4 three-phase circuits or 12 single-phase circuits at the same time.
It can measure parameters such as voltage and current, power, power factor, phase angle, unbalance, and harmonics.

Function
The specific functions are as follows:
①4-way three-phase or 12-way single-phase loop full electric parameter measurement, external current transformer;
②Monitoring each phase voltage/current, zero sequence current, frequency;
③Monitoring each phase power and total power (active, reactive, apparent);
④Monitoring each phase power factor and total power factor;
⑤Monitoring voltage/current phase angle, voltage/current unbalance；
⑥Monitoring total voltage/current harmonics and 2nd to 31th harmonics；
⑦Recording voltage, current and power extreme value of the current month and the previous month；
⑧Maximum current, maximum power demand and real-time current, real-time power demand；200 event loggings to record the actions of DIDO；
⑨Supporting overvoltage, overcurrent, phase failure, DI linkage and other alarm output；
⑩Rate setting for 4 time zones and 14 time periods；Four-quadrant energy, 12-month multi-rate energy statistics；
⑪31-day four-quadrant and multi-rate energy freeze, forward and reverse energy metering；
⑫Four passive switch inputs, two active switch inputs, one switch output, RS485 communication；
⑬Two-way passive switch input, two-way switch output, RS485 communication；
Note: It can only choose either-or between four passive switch inputs, two active switch inputs, one switch output and two passive switch inputs, two switch outputs.
