summary:

DDSF6111-4 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 to design and manufacture energy meters based on the actual electricity consumption of residents. This meter implements time-sharing measurement, sets daily automatic data transfer, LCD display and other functions. This meter can be set with 4 rates, 10 time periods, 4 time zones, and a 12 digit meter number, and has the function of outputting electric energy test pulses. 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/T645-2007 "Communication Protocol for Multi functional Energy Meters".

Functional 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,The time period can cross zero and is arranged from small to large 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 normal operationIn the environment, the clock error is controlled within 30s/month, and the built-in clock has calendar, timing, and leap year functionsAutomatic switching function. Using independent lithium batteries to power the clock, in order to maintain clock operation after power failureThe battery capacity is ≥ 1.0Ah, the battery life is over 10 years, and the continuous working time is greater than 3 years.

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