Electronic loads on the market have four basic functions. That is constant current, constant voltage, constant resistance and constant power. In the function is basically the same, the accuracy degree is almost the same, how to judge whether the electronic load meets the test requirements?

Electronic loads have only one set of operating circuits, the constant current function. Other functions are calculated according to Ohm's law. Although the nominal function is other, but the actual situation only constant current function, other functions are achieved by adjusting the current. This can save cost, but other functions are not high precision, unstable work. One popular saying is that there is no upper limit to the error of the constant resistance function. The completion of the test depends on the quality of the power supply, the external environment, and luck.

All functions of electronic load are realized by different circuits, which can completely complete all limit indicators and make the load stable. If only constant current function is used, other functions are not required, you can choose the appropriate, in line with the degree of electronic load. You need to consider this if other features require stable loading.
