Product Description
1. Product overall:
DDSF single phase multi-rate watt-hour meter is used to measure AC active power whose rated voltage is 220V and frequency is 50Hz in the single phase grid. it is a intelligent measuring meter which has the function of time-sharing measuring and charging and calculating automatically. Users can make electricity choices when you confront multi-rate in different time periods. The emergence of multi-rate products can cut electricity consumption and electricity bills. Therefore, the electricity energy can be consumed efficiently. This product can program and read meter and proof time through far IR when it is equipped with a PDA(meter reader) And it can realize contact-less data transmission and automation management when it is connected with a microcomputer.
2. Main features:
1. Display and record electricity consumption of peak, valley and equal, etc. multiple rate in the same month and the last month and total electricity consumption.
2. Display the current rate period.
3. Calculate total electricity, EI period, time, meter constant, meter reading time and parameters per time interval.
4. Set 8 time periods to let the power supply department make choice from the four rates.
5. The built-in storage can save data, and the data and information of blackout can be saved for 10 years.
6. It has the function of multiple encryption, anti-theft, anti-jamming, anti-attack.
7. Adaptive voltage range is wide: 170V-260V
8. High precision, wide load: IMAX=8Ib
3. Working principle:
Two major functions of this meter: one is electric energy measurement, the other one is microprocessor control. Electric energy measurement function of this meter adopts large-scale special integrated circuits, and produces pulse sequence which indicates how much power energy consumes, and send to the microprocessor for electric energy measurement. After the microprocessor receives pulse signal, through adding up input pulse quantity, and according to pulse constant to achieve accurate measurement of electric power and transfer data through various interfaces, and to implement various control functions.

5. Function overview:
1.Time-sharing measure reactive power, forward and reverse rates and maximum demand and time for each active and reactive power, measure active and reactive total power.
2.It can program 4 kinds of rates (tip, peak, flat, and valley), 8 day time period, 12 periods of time, and 4 time zones.
3.Except positive active power accumulation, reverse active power records reverse total, tip, peak, flat, valley electricity and recent 10 reverse operation starting time.
4.The external clock chip has the function of calendar, timing, anniversary switching automatically and temperature compensation.
5.LCD display with a wide viewing angle. Parameters display in turn automatically and the buttons display clearly.
6.With a RS485 interface and an infrared communication interface, and PC or PDA can communicate with the meter through the two communication interfaces, and both sides can communicate at the same time without interference.
7.Active,reactive testing pulse output, 1Hz clock output, multi-functional output and alarm lights alarm
8.It can record loss of voltage, phase failure, lose of current, overvoltage, under voltage, over current, voltage qualification rate, blackout and electricity recover, programming, demand reset and broadcasting timing ,etc.
9.It has functions of button, infrared and optical wake-up when blackout occurs. Optical wake-up is optional (within 3 days blackout), and it can wake up infrared meter reading.
9. It has the functions of fault information prompt, alarm (LCD, alarm lights, buzzer).
10. Load curve record
11. Instant freeze, zero freeze, forward active power freeze when time zone goes to end.
Load representative days the whole point of active power record.
12. Optional open the cover record.
13. Data saving period of validity after blackout: ≥10 years
14. LCD display all information, electricity quantity display 6 bits interger,1 bit decimal.
