summary:

The DTSU5881-F and DSSU5881-F three-phase electronic multi rate energy meters are designed using advanced energy metering chips combined with mature multi rate technology. They are designed and manufactured based on the actual electricity consumption of residents using digital sampling processing technology and SMT technology, and 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,The time period can cross zero and is arranged from small to large when set.The actual time and preset time of the start and end of any time period have an error of less than 5 seconds.The electric energy meter adopts a hardware clock circuit and has a temperature compensation circuit to ensure normal operation in the working cycleIn the environment, the clock error is controlled within 30 seconds/month, and the built-in clock has calendar, timing, and leap year functionsDynamic switching function. Using independent lithium batteries to power the clock, in order to maintain clock operation after power failure,The battery capacity is ≥ 1.0Ah, the battery life is over 10 years, and the continuous working time is greater 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)
