Ethernet three-phase multi circuit energy meter

1 Overview

DTSD1352-4S seriesEthernet three-phase multi circuit energy meterMainly used for full electrical parameter measurement of multiple circuits, up to 4 three-phase circuits can be connected simultaneouslyThe current input of the circuit or 12 single-phase circuits. It can measure parameters such as voltage, current, power, power factor, phase angle, imbalance, harmonics, etc.

2.2 Ethernet three-phase multi circuit energy meterTechnical Specifications

3 matching current sensors

The current sensor is a crystal head interface, three in one, with optional secondary output current50mA/100mV/333mV(Please specify when placing an order). customerThe current ratio can be modified through the instrument interface or communication based on the actual sensor specifications installed. The sensors are shown in Figures 1 and 2.

The ratio calculation is as follows:When the sensor outputs secondary current20mAWhen, the sensor specification isxxx A/20 mA，CT=2.5*xxx；When the sensor outputs secondary current50mAWhen, the sensor specification isxxx A/50 mA，CT=xxx；When the sensor outputs secondary current100mVWhen, the sensor specification isxxx A/100 mV，CT=xxx；When the sensor outputs secondary current333mVWhen, the sensor specification isxxx A/333 mV，CT=xxx；When users choose to actually connect to the Roche coil, they need to configure the sensor type to be "Roche coil" themselves (request configuration software from the R&D department).
