DTS/DSS three phase electronic watt-hour meter uses imported specific large-scale integrated circuits,16 bit A/D conversion, digital multiplier, digital sampling and processing technology and SMT technology. It is design and manufacture according to industrial user's electricity consumption.
With three independent units of measurement module, it can measures three-phase forward and reverse active power. Measurement error has excellent long-term stability. With high-quality tantalum capacitors, it has long service life.
It can prevent phase sequence errors, current reversal, different phase of voltage and current, voltage wire disconnection and zero disconnection etc. measurement errors and stealing behavior while wiring. It can measure three-phase active power which the rated frequency is 50HZ.
The main feature of the product: Anti-electromagnetic disturbance, low consumption, high precision, wide-range, anti-theft, wide range, long serve life, LCD display. The applicable environmental temperature is -10ºC~50ºC, the relative humidity can not be over 85%.
2. Working principle
This watt-hour meter adopts three-phase power supply, and it can work normally at any single phase power supply situation.
When this Watt-hour meter is working, voltage and current take samples through sampling circuit, and then send to large scale specific integrated circuit to buffer and magnify, and then 16-bit A/D converter converted into digital signal, an then convert into pulse which is proportional to electric energy through digital multiplier computation. Driving register accumulates power energy and drives pulse indicator, and output pulse for measurement.
3. Main features:
3.1 Three -phase active power measurement. It can work for a long time.
3.2 It is a instruction for lack of phase
3.3 Three-phase power supply. The precision of measurement can not be influenced when one or two phases interrupt.
3.4 Pulse output interface
