Description:Summarization: DDSF949 single-phase multi-tariff electronic meter uses large-scaled integrate circuit, SMT techniques, world-famous branded long-life components, 5+2 digit LCD and hardware timer. It can measure the 50Hz~60Hz single-phase AC active time-sharing consumption accurately. It meets the standard of GB/T17215-2002, GB/T15284-2002, DL/T614-1997 and some other relative national standard for multi-fee ratio electronic meter. It can be mainly used in the area of time-sharing measurement and can automatically read long-distance meter. It has good reliability, anti-tampering, wide load, low consumption, high accuracy, good anti-disturbance performance and working for a long time without calibration. Main function and characteristic: 1. Can measure the four different fee ratio consumption of tine, apex, flat and vale for 12 different periods accurately 2. Can store the tine, apex, flat and vale consumption of current, last months and the month before last 3. Has a temperature shading circuit for the timer to ensure the high accuracy with the error less than 0.5s/d 4. The data can be setup and read by RS485 and infrared interface, RS485 port is electric separated from the inside circuit of meter 5. Uses import lithium battery with life of 10 years 6. Can store data for 15 years when power off 7. Has test function for maximum demand 8. Can show all data recurrently and automatically or recurrently by pushing button 9. Can setup the date of automatically reading meter 10. Can judge the consumption direction and accumulate the reverse consumption to total consumption 11. Adopts both protection of encrypted code and programming switch to setup the data, automatically record the programming time and times Technical parameter: 1) Accuracy class: class 1 or class 2 2) Voltage circuit consumption: ≤1.5W, 6VA 3) Reference voltage: 110V, 120V, 220V, 230V, 240V 4) Basic (max. rated) current: 1.5 (6) A, 2.5 (10) A, 5 (20) A, 5 (30) A, 10 (40) A, 10 (60) A, 15 (60) A 5) Limited working temperature: -30 ~ +65°C 6) Relative humidity: ≤85% 7) Other technical parameter: impulse width 80ms±20ms
