Product Description
JWT5303 three-phase standard watt-hour meter is a kind of multi-function high-accuracy intelligent watt-hour measurement instrument which is designed with most advanced digital electronic technology end uses high-speed DSP processor, as its core technology. It comprises of high-speed DSP processor, two-way current frequency converter, digital controller, and digital display. Its voltage and current inputs are separated by passive transformer, so it is a kind of watt- hour measurement instrument with wide current measurement range, two-way current measurement capability, high accuracy, good stability, high overloading capacity, and strong practicability.
