DTSF866 / DSSF866 Three phase rail type multi rate electricity meter （7P）

Overview

The DTSF866 and DSSF866 three-phase electronic multi rate energy meters are designed using advanced energy metering chips combined with mature multi rate technology. They apply digital sampling processing technology and SMT technology, and are designed and manufactured according to the actual electricity consumption of residents. They are internationally advanced energy meters. 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

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. The actual time and preset time error of the start and end of any time period are less than 5 seconds. The electric energy meter adopts a hardware clock circuit and has a temperature compensation circuit to ensure that the clock error is controlled within 30 seconds/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 operation after a power outage. The battery capacity is ≥ 1.0Ah, and the battery life is over 10 years, with a continuous working time of more than 3 years.

3. Display function: three-phase current, three-phase voltage, three-phase power, frequency, rate period, etc.

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

5. Output function: Passive pulse output.

6. Event recording function: 1. It has a 12-month historical power consumption; 2. Maximum demand (optional)
