Problems solved by technology

There are many types of power supplies used by servers, ranging from 300W to 1200W, and even higher power supplies. These power supplies usually use electronic instruments such as Chrome testers to test the output signal and software version of the power supply when entering the factory. Although the tester can also test the load performance, it is only a software simulation after all, it cannot provide a real load, and the operation is complicated
Some problems with the power supply (such as power failure after working in a load environment for a period of time, abnormal operation of the single power supply alarm mechanism, etc.) cannot be detected by the tester alone, and a server environment needs to be built for testing, which is cumbersome. Greatly increased the workload of factory inspection

Abstract

The invention provides an extensible simple power source aging test instrument based on a basic resistor circuit, and belongs to the field of server power source aging. According to the extensible simple power source aging test instrument based on the basic resistor circuit, the basic pure resistor circuit is adopted, cement resistors which are large in power consumption and good in heat radiation with different resistance power consumptions are simply connected in parallel and series, different load circuits are obtained in a matched mode, different load combinations are selected through switches, and the effect of simulating a load environment is achieved. If it is necessary, an original circuit can be extended, and therefore the requirement for a larger load is met. The load environment of a power source can be well simulated, operation is simple, and an extensible function is achieved.

Description

[0001] technical field [0002] The invention relates to the field of server power supply aging, in particular to an expandable and simple power supply aging testing instrument based on a basic resistance circuit. Background technique [0003] With the development of new technologies such as cloud computing and big data, the demand for servers is increasing. There are many types of power supplies used by servers, ranging from 300W to 1200W, and even higher power supplies. These power supplies usually use electronic instruments such as Chrome testers to test the output signal and software version of the power supply when entering the factory. Although the tester can also test the load performance, it is only a software simulation after all, it cannot provide a real load, and the operation is complicated. Some problems with the power supply (such as power failure after working in a load environment for a period of time, abnormal operation of the single power supply alarm m...
