Abstract
This invention provides one electron load switch device to load the system onto power, which comprises one power input end to connect power and electron load switch device; input current to test power input end and to output one current measurement signal test module to receive the test module signals and to display the display module; load consumption terminal to load each independent power load by plug type to receive the input current.
Description
[technical field]
The present invention more in detail, loads on power supply with inserting mode with system load and external load relevant for a kind of relevant for a kind of electric loading switching equipment, and the electric loading switching equipment of the electric current situation of change of synchronous monitoring power supply full load.
[background technology]
The power supply full load, output end voltage can produce tangible drift, and power source loads test (Load PowerSupply Test) is under the state that system power supply is fully loaded with, can testing power supply and this system stablize running.In the practical operation; the electronic load that power supply consumed except system; not enough will supplying by the external load supply; the method of supplying load at present is that each is partly removed the outer layer insulation of power transmission line, directly each power source loads is sandwiched in the current-carrying part of each transmission line, so can be because of the composition surface loose contact; influence the accuracy of test result; and the current-carrying part of this transmission line is exposed to the outside, lacks insulation protection, has potential potential safety hazard.In addition, this power source loads test needs to load a current measuring device between this electronic system and this power supply, with the variation of real-time monitored current value, increases the complicacy of this system.
Therefore, being necessary to provide a kind of loads on power supply with inserting mode with system load and external load in fact, and the electric loading switching equipment of the electric current situation of change of synchronous monitoring power supply full load.
[summary of the invention]
Purpose of the present invention promptly provides a kind of electric loading switching equipment, is used for system load and external load being loaded on power supply with inserting mode, and the electric current situation of change of synchronous monitoring power supply full load.
For reaching above-mentioned purpose, the invention provides a kind of electric loading switching equipment, comprise the power input that connects power supply and this electric loading switching equipment with inserting mode, in order to measure the input current of this power input, and export the measurement module of a current measurement signal, in order to current measurement signal that receives this measurement module and the display module that is shown, and in order to receiving the electric current of this power input, and load on the load consumption end of each independent current source load with inserting mode.
Compared to prior art, electric loading switching equipment of the present invention loads on power supply with inserting mode with system load and external load, reaches relative stability and security in test process.In addition, but the electric current situation of change of this electric loading switching equipment synchronous monitoring power supply full load is analyzed the stability of this electronic system whereby, improves the ageing of test.
[description of drawings]
Fig. 1 is the block diagram of electric loading switching equipment of the present invention.
