Programmable direct-current power supply

Abstract

The invention discloses a programmable direct-current power supply, which comprises a shell, wherein a front panel is arranged on the front side of the shell, and is provided with a display screen fordisplaying a user interface, an auxiliary function soft key used for menu display is arranged on the lower side of the display screen, a USB Host interface allowing an external USB driver to be connected to equipment is arranged on the left side of the display screen, multi-channel voltage output is provided, the total output power reaches up to 200 W, the output of all channels is independentlycontrollable, voltage stabilization and current stabilization value stepping of the first path and the second path are adjustable, two working states of voltage stabilization and current stabilizationcan be automatically switched along with the change of a load, the first-path output and the second-path output can be connected in series, connected in parallel and independently work, and the thirdpath provides four selectable output voltages of 1.8 V, 2.5 V, 3.3 V and 5V.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a programmable DC power supply. Background technique [0002] The DC power supply has two electrodes, positive and negative. The potential of the positive electrode is high, and the potential of the negative electrode is low. When the two electrodes are connected to the circuit, a constant potential difference can be maintained between the two ends of the circuit, thereby forming an external circuit from the positive electrode to the negative electrode. Negative current; [0003] The current DC power input and output on the market require different channel interfaces, resulting in too few input channels or output channels in the operation panel, which cannot meet the needs of users; in addition, the current DC power technology is not smart enough. When multi-channel output is required at the same time, it is impossible to provide fast and convenient synchronization and multi...

Problems solved by technology

[0003] The current DC power input and output on the market require different channel interfaces, resulting in too few input channels or output channels in the operation panel, which cannot meet the needs of users; in addition, the current DC power technology is not smart enough. When multi-channel output is required at the same time, it is impossible to provide fast and convenient synchronization and multi-channel common output. It often requires the use of multiple DC power supplies to achieve it, which brings bad experience to users and is inconvenient to use;

[0004] The existing technology can no longer meet the needs of people at the present stage. Based on the current situation, there is an urgent need to reform the existing technology
