Problems solved by technology

Since most of the loads currently use power dissipation resistors, the power consumption is wasted, which is really intolerable in today's energy shortage, and this kind of power resistor has poor precision and high heat generation, which makes it difficult to guarantee the effect of aging detection, and pollutes the environment. There is also a risk of fire
[0003] To sum up; the power consumption resistive load used in the current DC power supply aging detection in the prior art has the defects of wasting energy, polluting the environment, and not being effective

Description

technical field [0001] The invention relates to a multi-channel wide voltage input electric energy feedback type electronic load. Background technique [0002] In today's increasingly developed electronic industry, various electronic products are changing with each passing day. These numerous electronic products have different functions and purposes, but they have a common feature: they need one or more sets of DC power supplies, so various DC power supplies Manufacturing and production are very popular industries today. Take the computer industry as an example. Every computer must have a power supply. Who can tell how many computers there are in the world? The output is endless, how much power supply needs to be produced to meet the demand. The power supply for this kind of computer usually adopts switching power supply. In addition to switching power supply, the DC power supply used by other electrical appliances also includes rectifying power supply, regulated power supp...
