Handheld power harmonic analyzer DYXB-6A

1、 Product introduction

With the vigorous development of China's national economy, power load has increased dramatically, especially the continuous growth of impulsive and nonlinear load capacity, which has caused power quality problems such as waveform distortion, voltage fluctuation and flicker, and three-phase imbalance. The company's harmonic analyzer is a high-performance multi-function harmonic analyzer. DSP+ARM+CPLD core, 3.2 "large screen LCD (320 × 240 dot matrix) display, making the structure more compact, the function more powerful and the display more convenient. Background management and analysis software, with rich functions and convenient operation.
