Product aging tester

Abstract

The invention discloses a product aging tester which comprises a mains supply, wherein 220 v alternating voltage of the mains supply is input to a power transformer and a switching power supply, the 220 v alternating voltage is converted to 12 v direct voltage by the switching power supply and then input to a current and voltage display circuit, and the 220 v alternating voltage is converted to 9 v and 12 v direct voltage by the power transformer and then input to a master control power supply and a fan power supply. An output end of the master control power supply is connected with a power light, a high-precision reference circuit, a master control constant current circuit and a current consumption load. An output end of the fan power supply is connected with an automatic fan control circuit. An input end of the current consumption load is connected with the master control constant current circuit and the automatic fan control circuit. An output end of the high-precision reference circuit is connected with a current regulator, and the current regulator is connected with the master control constant current circuit. An output end of the current consumption load is connected with the current and voltage display circuit. The product aging tester has the advantages of being simple in assembly, simple in usage, low in cost, and easy to produce in large quantities.

Description

technical field [0001] The invention relates to the technical field of aging testing, in particular to a product aging testing device. Background technique [0002] Before the electronic products leave the factory, aging treatment is usually carried out, and the products after aging treatment are tested to eliminate unqualified products. The current product aging test device is complicated and complicated to adjust the current, the current is unstable, and the current drifts. The circuit is complicated, there are many components, the cost is high, and the standby power consumption is high. In the process of making the aging device, debugging and proofreading are required. Contents of the invention [0003] In order to overcome the above disadvantages in the prior art, the object of the present invention is to provide a product aging testing device with stable product quality, high production efficiency and power saving. [0004] In order to achieve the above-mentioned pur...
