KDZD5000 power quality analyzer is a three-phase, multi-functional, intelligent, human-machine operation simple comprehensive test instrument developed by our company. It has the characteristics of easy to use, large LCD color display, high resolution, anti-vibration structure housing and so on.

KDZD5000 power quality analyzer adopts DSP+ARM dual processor architecture, DSP is responsible for data acquisition and algorithm processing, ARM is responsible for communication protocol and man-machine interface processing. Analog signal acquisition is completed with two Analog Devices 4-channel synchronous sampling AD7655 with 16-bit resolution, achieving a maximum sampling rate of 1MSPS, enabling more accurate detection of transient waveforms, sudden surges, sudden drops, and instantaneous interruptions. The working frequency of DSP is more than 200MHz, which can timely monitor the power grid and dynamically adjust the sampling frequency to realize the synchronization of power frequency and sampling frequency.
