The contactless voltage regulator mainly consists of an isolation transformer, SCR module, CPU control core, and safety protection device. By adopting the latest DSP operation measurement chip control technology, fast AC sampling technology, effective value correction technology, current zero crossing switching technology, and fast compensation voltage stabilization technology, intelligent instruments, fast voltage stabilization, and fault diagnosis are combined to achieve contactless control, making the product safer, more efficient, and more precise.
No contact: no contact regulator has no mechanical switch, so it has the advantages of long life and high reliability
High efficiency: the conversion efficiency of the contactless regulator is high, generally more than 90%,
strong adaptability: the contactless regulator can adapt to a wide range of input voltage and load changes, and has fast response ability
low noise: no contact regulator has no mechanical switch noise, so it has the characteristics of low nois
small size, light weight: the volume and weight of the contactless regulator are smaller than that of the contact regulator, easy to install and use
