Product details
DDS388L single-phase electronic energy meter adopts advanced solid-state integrated circuit technology and SMT process, suitable for measuring AC single-phase active energy with a frequency of 50Hz, and its performance meets the technical requirements of GB/T 17215.321-2008. This product has a bidirectional metering function, which can accurately measure active energy in both positive and negative directions, and can set a combination of active energy based on this. It also has a time-sharing metering function; The active electrical energy is accumulated and stored separately based on the peak, off peak, off peak, and off peak periods, as well as the total electrical energy. It has LCD display function (with button wake-up LCD display function during power outage), RS485 and infrared communication function. The load switch control method is divided into two types: built-in switch and no switch.
1. Supports 4 rates, 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. Supports tiered electricity pricing function, does not support tiered electricity pricing, requires backend settlement.
3. Support zeroing function under key and permission conditions. The minimum reading of the electric energy meter can only be zeroed and cannot be set.
4. Support data storage function, which can store bidirectional total electricity and electricity rate data for the past 12 settlement days.
5. Support freezing function, with methods such as timed freezing, instant freezing, daily freezing, agreed freezing, and hourly freezing.
6. Support event recording function, which can record the total number of power outages, programming, timing, opening and closing events 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.
7. 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.
1. Accuracy: Level 1, Level 2.
2. Rated voltage (Un): 220V, maximum operating voltage: 0.7Un~1.2Un.
3. Current specifications: 1.5 (6) A, 5 (30) A, 5 (60) A, 10 (60) A, 10 (100) A.
4. Basic error, start-up and creep: comply with the requirements of GB/T 17215.321-2008.
5. Dimensions: 160mm x 118mm x 71mm.
6. Installation dimensions: 140 (150) mm x 105mm.
7. The communication protocol complies with DL/T 645-2007 "Multi functional Energy Meter Communication Protocol" and its filing documents.
8. The rate function complies with the requirements of DL/T 614-2007 protocol.
9. The external dimensions comply with the Q CSG 113011-2011 single-phase electronic energy meter external structure specification.
10. The technical parameters comply with the Q CSG 113003-2011 technical specifications for single-phase electronic energy meters.
