Abstract

The invention belongs to the technical field of mobile power sources, and particularly relates to a UPS power source with an output voltage adjusting function. The UPS power source comprises a shell, a sliding groove formed in the shell, and a voltage adjusting switch arranged in the sliding groove, and the voltage adjusting switch slides in the sliding groove. The UPS power source with the output voltage adjusting function can adjust output voltage, the output voltage can be adjusted to the output voltage meeting rated input voltage of an electronic product according to the rated input voltage of the electronic product, operation is convenient, and it can be avoided that equipment is damaged by the electronic product due to inconformity of the output voltage, and the service life of the equipment is affected.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a UPS power supply with the function of adjusting output voltage. Background technique [0002] UPS (Uninterruptible Power System / Uninterruptible Power Supply), that is, uninterruptible power supply, is a system device that connects batteries (mostly lead-acid maintenance-free batteries) with the host, and converts DC power into commercial power through modular circuits such as host inverters. . It is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment. The existing UPS power output is 220V alternating current, and the use of some equipment requiring 110V or 380V power supply is limited. Contents of the invention [0003] The purpose of the invention is to overcome the problem that the output voltage of the existing UPS power supply cannot be adjusted. [0004] To th...
