Embodiment 1

[0012] a kind of like figure 1 The shown UPS power supply with adjustable output voltage is a UPS power supply with adjustable output voltage. Lamp 2: The UPS power supply with adjustable output voltage is to adjust the output voltage by adjusting the resistance connected in series in the circuit through the rotary rheostat in series with the output voltage through the knob 3 (existing technology), and can adjust the output voltage according to the rated input voltage of the electronic product Adjusting the output voltage to conform to the rated input voltage of the electronic product is not only convenient but also can avoid damage to the electronic product caused by the output voltage not meeting the requirement.

Embodiment 2

[0014] For the above-mentioned UPS power supply with adjustable output voltage, the knob 3 is located in the front of the UPS power supply, in the upper left corner, and the character 4 indicating the output voltage is also provided on the casing 1. The character 4 is located in front of the LED light 2. When the knob is turned 3 will increase or decrease the resistance connected in series in the output circuit, thereby reducing or increasing the voltage in the output circuit, and the LED indicator 2 and the corresponding character 4 can display the current output voltage.

Abstract

The invention belongs to the technical field of portable power supplies and particularly relates to a UPS achieving adjustable output voltage. The UPS comprises a shell and further comprises a knob arranged on the shell and LED indicator lights arranged on the top surface of the shell. According to the UPS achieving adjustable output voltage, output voltage can be conveniently adjusted to output voltage according with rated input voltage of an electronic product according to the rated input voltage of the electronic product, and the situation that output voltage doses not accord with the rated input voltage and damages the electronic product and equipment and consequently the service life of the equipment is influenced can be avoided.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a UPS power supply with adjustable 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] Therefore, the prese...
