Energy-saving electrified ageing device for switch power supplies

Abstract

The invention discloses an energy-saving electrified ageing device for switch power supplies, which comprises a plurality of switch power supplies, a plurality of current restrictors, a current junction station and an electric supply supplementation inverter power supply, wherein the current junction station is used for collecting currents output by the switch power supplies; the electric supply supplementation inverter power supply serves as the mutual load of the switch power supplies, synchronously converts direct current collected by the current junction station into alternating current to supply power for the switch power supplies, and can automatically start a 220V alternating current power supply to supplement power supply for the plurality of power supplies under the condition that self-supplied power is insufficient; and a 220V alternating current on-off control switch capable of automatically controlling the on-off state is connected in series between the electric supply supplementation inverter power supply and the 220V alternating current power. The energy-saving electrified ageing device for switch power supplies is reasonable to design, is convenient to wire, is convenient to operate and has the advantages of low cost, good use effect and low energy consumption, the practical problems of high input cost, serious electric energy consumption and the like existing in the traditional power supply ageing device can be effectively solved, and the power supply ageing cost is lowered.

Description

technical field [0001] The invention relates to an energy-saving aging device for a power supply, in particular to an energy-saving aging device for a switching power supply. Background technique [0002] The aging test of electronic products is a necessary means to eliminate early failure of electronic products and control product quality. At present, the common method for aging test of switching power supply in China is to add a resistance load in the circuit of switching power supply, but the above-mentioned traditional aging method is unreasonable in design and the waste of electric energy is huge in the actual use process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a switching power supply energy-saving charging aging device for the above-mentioned deficiencies in the prior art. It solves the practical problems of high input cost and serious waste of electric energy in traditional power aging devices, ...
