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.
Fast response speed: Because the contactless regulator is controlled by electronic components, its response speed is faster than the traditional mechanical regulatorIt can quickly adjust the output voltage to adapt to changes in the input voltage.
High stability: the contactless regulator can maintain the stability of the output voltage in the case of large input voltage fluctuations,and effectively prevent the damage of voltage fluctuations to electronic equipment.
Long life: Because the contactless regulator does not involve mechanical parts, it has a long service life.Compared with mechanical regulators, contactless regulators are more reliable and less prone to failure.
High efficiency and energy saving: the contactless regulator uses electronic components to adjust,compared with the mechanical regulation of the traditional regulator, it can more effectively convert electrical energy, reduce energy loss, and improve energy efficiency.
Small size: The contactless regulator is controlled by electronic components, which can achieve a more compact design,making the device smaller and more suitable for application in space limited occasions.
