Product Description
1. Product overview: DDS single phase electronic watt-hour meter uses imported specific large-scale integrated circuits, A/D conversion, digital multiplier, digital sampling and processing technology and SMT technology. It can measure AC single phase active electric power which the rated voltage is 220V and frequency is 50Hz. It can measure forward and reverse active power accurately and it calculates accumulatively in the same direction. It can prevent electric larceny at the same time. It outputs heartbeat through optical couple. LCD displays electricity consumption, so that it is easy to control. It is design and manufacture according to industrial user's electricity consumption. 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 single phase active power whose 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 When this Watt-hour meter is working, voltage and current take samples through sampling circuit, after A/D conversion, it sends to multiplier to multiply, after conversion through D/F converter, pulse output from frequency dividing circuit send to single chip CPU to data processing and measurement, single chip CPU communicates with outside and set, manage and display the meter through infrared extension and RS485 interface.3. Main features: Single phase active power measurement. It can work for a long time.It conducts Signal sampling from shunt voltage divider. It can drive a stepper motor to let the register calculate the energy degrees cumulatively through the processing of amplification, multiplication, integration, V/F conversion, frequency division, power driver, etc.4.
