Product Specification
DTZY88-Z three-phase multi-function electric energy meter (built-in carrier)
I. Overview
DTZY88-Z three-phase multi-function electric energy meter (built-in carrier), using advanced solid-state integrated circuit technology and SMT technology, suitable for measuring AC three-phase active and reactive energy with a frequency of 50 Hz, and its performance complies with GB17215.321-2008 skills requirement. This product has a two-way metering function, which can accurately measure active and reactive energy in both positive and negative directions. It has a time-sharing metering function. The electrical energy is divided into peak, peak, flat, valley and other time periods and total electrical energy. Accumulate and store; can record demand and load curves; LCD display function (with button wake-up LCD display function when power failure), RS485, narrowband carrier communication and infrared communication functions.

three. The main function
1. Support 4 rates, maximum 14 time zones throughout the year, 14 time periods can be set every day, two sets of rate timetable switching, and special timetable settings for holidays.
2. Support the data storage function, which can store the two-way total electric energy and the electric energy data of various tariffs for the last 12 settlement days.
3. Support freezing function, with time freezing, instantaneous freezing, daily freezing, agreed freezing, and whole point freezing.
4. Support event recording function, can record the total number of power failures, the total number of programming, the total number of time calibration, the total number of open meter cover; can permanently record the time of the electricity meter clearing event and the electrical energy data at the time of clearing, etc. .
5. With load recording function, it can be defined from DL/T 645-2007 "voltage, current, frequency", "existing and reactive power", "power factor", "existing and reactive total energy", "four quadrants" Any combination of the six types of data items "total reactive energy" and "current demand".
6. Support alarm function, with light alarm output. The light alarm uses a red constant light indicator, and the alarm automatically ends when the event returns to normal.
7. It has 1 infrared communication interface, 2 RS485 communication interfaces, and narrowband carrier communication interface.
8. Record the cumulative total loss time, the time of the last 10 full loss of voltage, the recovery time, and the voltage, current, power, power factor, positive and negative active power, positive and negative of each phase at the time of occurrence. 8. Information such as reactive power and current.
9. Optional narrowband carrier communication module commonly used in China at present, the carrier module is built-in and cannot be replaced.
10. Support power failure wake-up function.
