    Application of DC Power Supply in Fuse/Fuse Testing
    Background: Fuses, or fuses, need to input a fixed voltage to test the quality of fuses. There are two main test requirements for testing fuses: 1. Agreed non fusing current: It is mainly to input a fixed current to the fuse within the specified time to ensure that the fuse will not be blown. 2. Agreed fusing current: input a fixed current within a certain period of time, and the fuse will be blown to protect the circuit. Scheme Details: Agreed non fusing current test: the constant current output of the DC power supply is selected, the current output is stable, the fuse is directly connected, the current is close to the theoretical current value, and the online adjustment function is required. The oscilloscope is used to collect and view the waveform. Agreed fuse current test: the wiring method is the same as the agreed non fusing current test. Test the fusing time, set the power supply to 14V, and adjust the constant current to the rated current. When the air switch is closed, collect the time and current characteristic curve when fusing. Solution: The APM SP-1U/2U series high-performance programmable DC power supply has two operating modes: constant voltage and constant current. The voltage range is 0~800V. The constant current mode can provide constant current to the fuse and can be adjusted online to meet the two test requirements of the fuse.

    Detailed Explanation of Common Fault Solutions for Switching Power Supplies
    As a power conversion device, switching power supply can be seen everywhere in life, and most people rarely know its basic common sense and function. A switching power supply is a small portable power conversion device, which generally consists of a casing, a switch, a power transformer and a rectified current. It can be divided into AC output type and DC output type. Generally, there are two types: wall-plug type and desktop type. In the use of switching power supply, it is inevitable that some faults will occur over time. So what are the common faults of switching power supply and how to solve them? In the use of switching power supply, faults such as blown fuse, unstable voltage output, no DC voltage output, and reduced power load capacity often occur. After a problem occurs, there will be some manifestations, which can help users find the reason for the user and do a good job Maintenance or even replacement. The blown fuse is a common problem. The biggest reason for this problem occurs when the components and open-circuit power supply are damaged. In the case of a blown fuse in the product, do not allow the maintenance personnel to change the fuse casually, and then turn it on immediately. The reason for the fuse is that blind booting is likely to cause a secondary fuse. If the power supply used in the computer is frequently powered off, if the hard disk tells to write, it will easily cause damage to the hard disk, which is not worth the loss. . The damage of the fuse is generally caused by a problem with the components, and the fundamental problem can be solved to avoid this situation from happening again. Poor load capacity generally occurs in power supplies that work for a long time. The aging phenomenon of long-term use is also the biggest cause of t
