Problems solved by technology

[0002] The power supply voltage of the industrial site fluctuates greatly and the interference is strong, which may easily lead to abnormal operation or even damage of the power supply of the field instrument
Although industrial instrumentation suppliers have done many modular reliability designs, the deterioration, failure, and performance consistency of components will cause the product to be unable to be used normally on site

Abstract

The invention relates to the technical field of power supplies. The power supply system for the product aging and reliability test comprises an upper computer monitoring system, a power supply voltageoutput circuit, a power supply power detection circuit, a fault protection circuit and an MCU control circuit, and the upper computer monitoring system is used for displaying faults of a tested instrument and setting test parameters of the tested instrument; the power supply voltage output circuit provides a power supply for the tested instrument, the power supply power detection circuit is usedfor detecting the power supply power of the tested instrument, and when the MCU control circuit detects that the tested instrument has a fault, the power supply voltage output circuit is disconnectedthrough the fault protection circuit. According to the invention, various severe power supply voltages which are connected to a power supply port in series in an industrial field are simulated, powersupply performance aging and reliability tests are carried out through the method, faults of a tested instrument power supply part caused by external high-pulse voltage interference can be improved, and reliability and stability of the tested instrument power supply part are improved.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply system for product aging and reliability tests. Background technique [0002] The power supply voltage of the industrial site fluctuates greatly and the interference is strong, which may easily lead to abnormal operation or even damage of the power supply of the field instrument. Although industrial instrumentation suppliers have done many modular reliability designs, the deterioration, failure, and differences in performance consistency of components will cause the products to be unable to be used normally on site. Therefore, it is particularly important to test the power supply performance of the instrument before it is applied to the field. Contents of the invention [0003] The invention provides a power supply system for product aging and reliability tests, which can simulate various harsh conditions encountered by the power supply in actual use, makin...
