DTSDU866-W / DSSDU866-W Three phase rail type multifunctional electric energy meter (Simple type with reactive power 4P)

Overview

The DTSD866-W three-phase rail type multifunctional energy meter (hereinafter referred to as the instrument) is an indoor three-phase energy meter designed and developed by our company to adapt to China's power grid transformation and national conditions. It has high accuracy and feasibility. This instrument adopts internationally advanced ultra-low power large-scale integrated circuit technology and SMT advanced process. The key components are selected from international brands and long-life devices, which improves the reliability of the product and extends its service life. Accurately measure active energy and can read the amount of electricity through infrared communication, making the reading intuitive and easy to use. This instrument design complies with the relevant technical requirements for three-phase static energy meters in standards GB/T 17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters", GB/T 17215.323-2008 "Level 2 and Level 3 Static AC Reactive Energy Meters", and DL/T 645-1997 "Communication Protocol for Multi functional Energy Meters".

Features

1. Active energy, active power, power factor, current, voltage, frequency, reactive energy, reactive power, communication.

2. Three phase power supply, one or two phases of power outage, measurement accuracy is not affected. After the three-phase power supply is cut off, all stored data will not be lost and can be maintained for more than 10 years.

3. It has the function of coupling isolated active and passive pulse test port output (meeting the requirements of remote pulse output, with a pulse width of 80ms ± 20ms).

4. Alarm function, the alarm indicator light will turn off when there is a phase loss.

5. Communication protocol: Supports DL/T645 or Modbus RTU protocol.
