DDSF866 Single phase rail type multi rate electricity meter (4P)

Overview

The DDSF866 single-phase electronic multi rate energy meter is designed using advanced energy metering chips combined with mature multi rate technology. It applies digital sampling processing technology and SMT technology, and is designed and manufactured according to the actual electricity consumption of residents. It is an internationally advanced energy meter. This meter implements time-sharing measurement, sets daily automatic data transfer, programs and reads meters on handheld terminals or PCs, and displays on LCD screens. This meter can be set with 4 rates, 10 time periods, 4 time zones, and a 12 digit meter number, and has the functions of power testing pulse output and maximum demand. The performance indicators of this meter comply with GB/T 17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters", GB/T 15284-2002 "Special Requirements for Multi Rate Energy Meters", and the communication protocol complies with the requirements of DL/T645-1997 "Communication Protocol for Multi functional Energy Meters".

Features

1. Measurement function

2. Multi rate function

2.1 Four rates can be set, including peak, off peak, flat, and valley rates, for a period of 10 days. The minimum interval between time periods is 1 minute, and the time periods can cross zero. They are arranged in ascending order when set.

2.2 The actual time and preset time of the start and end of any time period have an error of less than 5 seconds.

2.3 The electric energy meter adopts a hardware clock circuit and has a temperature compensation circuit to ensure that the clock error is controlled within 30s/month under normal working conditions. The built-in clock has calendar, timing, and leap year automatic switching functions. The clock is powered by an independent lithium battery to maintain its working capacity of ≥ 1.0Ah after a power outage. The battery has a lifespan of over 10 years and can work continuously for more than 3 years.

3. Display content: current, voltage, power, rate period, frequency, etc.

4. Communication function: Supports DL/T645 or Modbus RTU protocols

5. Output function: Passive pulse output

6. Event recording function: There is a history of active contributions in the past 12 months

7. Equipped with battery voltage loss alarm function
