　　1 Overview

DTSD1352-4S seriesRail type multi circuit power meterMainly used for full electrical parameter measurement of multiple circuits, it can simultaneously connect up to 4 three-phase circuits or 12 single-phase circuits for current input. It can measure parameters such as voltage, current, power factor, phase angle, imbalance, harmonics, etc.

　　2 Product functions and technical parameters

　　2.1 Product Features

The specific functions are as follows:

Measurement of full electrical parameters for 4-channel three-phase or 12 channel single-phase circuits, with external current transformers;

Monitor the zero sequence current frequency of each phase voltage/current;

Monitor the total power of each phase (active and reactive power);

Monitor the power factor of each phase and the total power factor;

Monitor voltage/current phase angle and voltage/current imbalance;

Monitor the total harmonic and 2-31st harmonic of voltage and current;

Record the extreme values of voltage, current, and power for the current month and the previous month;

● Current power demand and real-time current real-time power demand;

200 event records, recording the action status of DIDO;

If the current transformers are different, customers can modify the current ratio through the instrument interface or communication according to actual usage. The transformer is shown in Figure 1 and Figure 2.
