Constant voltage, constant frequency, uninterruptible power supply (CVCF) mounting, video equipment for outdoor advertising

摘要

This study considers that the existing mobile imaging equipment adopts the power supply device, the noise problem caused by the generator, the problem of shortening the service life of the various shift equipment, and the problem of quality degradation of the imaging equipment caused by the unstable power supply. In order to solve the positive voltage of the rechargeable battery in the power supply department technically, Replacing it with "CVF gt", a non-government power supply equipment of Zhengzhou group, can make up for the above shortcomings.In this study, by installing additional external charging battery, the capacity shortage of the internal charging battery of voltage, directional wave, non fixed power and power supply equipment is solved.
