Overview

Acrel DTSD1352-4S series DIN-rail type multi-circuit power meter is mainly used for Data center,telecom Tower station the full electric parameter measurement of multiple circuits, and could be connected to the current input of 4 three-phase circuits or 12 single-phase circuits at the same time. It could measure parameters such as voltage and current, power, power factor, phase angle, unbalance, and harmonics.

Product function

The specific functions are as follows:

4-way three-phase or 12-way single-phase loop full electric parameter measurement, external current transformer;

Monitoring each phase voltage/current, zero sequence current, frequency;

Monitoring each phase power and total power (active, reactive, apparent);

Monitoring each phase power factor and total power factor;


Monitoring voltage/current phase angle, voltage/current unbalance;

Monitoring total voltage/current harmonics and 2nd to 31th harmonics;

Recording voltage, current and power extreme value of the current month and the previous month;

Maximum current, maximum power demand and real-time current, real-time power demand;

200 event loggings to record the actions of DIDO;

Supporting overvoltage, overcurrent, phase failure, DI linkage and other alarm output;

Rate setting for 4 time zones and 14 time periods;

Four-quadrant energy, 12-month multi-rate energy statistics;

31-day four-quadrant and multi-rate energy freeze, forward and reverse energy metering;

Four passive switch inputs, two active switch inputs, one switch output, RS485 communication;

Two-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.

Matching transformers

The current transformer is a crystal head interface, the primary side current is 50A-600A . If the current transformer is different, the customer can modify the current transformation ratio through the instrument interface or communication according to the actual use. The transformer is shown in Figure 1 and Figure 2.
