Product details
The DTZY88-Z three-phase multifunctional energy meter (with built-in carrier) adopts advanced solid-state integrated circuit technology and SMT process, and is suitable for measuring AC three-phase active and reactive energy with a frequency of 50Hz. Its performance meets the technical requirements of GB17215.321-2008. This product has a bidirectional metering function, which can accurately measure active and reactive energy in both positive and negative directions. It has a time-sharing metering function, and the electrical energy is accumulated and stored separately according to the peak, peak, flat, valley and other time periods, as well as the total electrical energy; Can record demand and load curves; Has LCD display function (with button wake-up LCD display function during power outage) RS485、 Narrowband carrier communication and infrared communication functions.
1. Supports 4 rates, up to 14 time zones throughout the year, 14 time periods can be set per day, switching between two sets of rate time period tables, and supports setting special time period tables for holidays.
2. Support data storage function, which can store bidirectional total electricity and electricity rate data for the past 12 settlement days.
3. Support freezing function, with methods such as timed freezing, instant freezing, daily freezing, agreed freezing, and hourly freezing.
4. Support event recording function, which can record the total number of power outages, programming, timing, and opening of the meter cover; It can permanently record the occurrence time of the reset event of the energy meter and the energy data at the time of reset.
5. It has a load recording function and can combine any of the six data items defined in DL/T 645-2007, including "voltage, current, frequency", "active and reactive power", "power factor", "total active and reactive energy", "total reactive energy in four quadrants", and "current demand".
6. Support alarm function, with light alarm output. The light alarm adopts a red constant light indication, and the alarm will automatically end when the event returns to normal.
7. It has one infrared communication interface, two RS485 communication interfaces, and a narrowband carrier communication interface.
8. Record the cumulative total voltage loss time, the time of the last 10 total voltage losses, the time of recovery, as well as the voltage, current, power, power factor, positive and negative active power, positive and negative reactive power, current, and other information of each phase at the time of occurrence.
9. Optional narrowband carrier communication module commonly used in China, the carrier module is built-in and non replaceable.
10. Support power outage wake-up function.
