DDSD866 Single phase rail type multifunctional electric energy meter (全功能)

Overview

The DDSD866 model is designed with an advanced microcontroller processing system, which has the advantages of simple circuit, high reliability, and high accuracy. This product has advanced software, hardware, and structural design technology, high measurement accuracy, and combines microcontroller resources to achieve active energy time-sharing measurement, current, voltage, power, and power factor measurement. It has RS-485 communication function, good anti-interference and anti attack performance, wide working temperature range, and can work stably and reliably for a long time. The various error performance indicators of this product comply with the technical requirements of national standards such as GB/T 17215.321-2008 "Level 1 or Level 2 Static AC Active Energy Meter" and DL/T 645-1997 "Multi functional Energy Meter Communication Protocol", and the "Customizable MODBUS Communication Protocol".

This energy meter measures single-phase two-wire active energy and is suitable for secondary circuit users who implement multi rate electricity pricing or for single-phase electrical equipment with limited space. It can be read through RS485 communication network and has the characteristics of good reliability, small size, light weight, beautiful appearance, and flexible installation.

Features

1. Power outage display (optional)

2. Active energy is measured in both directions, and reverse energy is included in the total electricity consumption

3. Reverse metering

4. Real time current, voltage, active power, power factor, frequency measurement display

5. Four rates (peak, off peak, off peak, valley) can be set for 10 time periods, including reactive energy and reactive power (optional)

6. Automatic monthly settlement function, which can save the historical electricity data of the past 12 months and read it through RS485 communication

7. Programming and meter reading operations can be completed through the RS-485 communication interface, and RS485 can work normally at 80% -115% of the rated voltage of the meter.

8. Support far-infrared communication

9. Communication: Supports DL/T645 or Modbus RTU protocols

10. Passive pulse output, compliant with DIN43864 standard

11. After power failure, all stored data will not be lost and can be maintained for more than 15 years
