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.
Electronic Single-Phase Multi-Rate Watt-Hour Meter

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.
