What is Electronic Load and How to Use It Correctly?

What is electronic load? In the narrow sense, electronic load  is (or equivalent to) an adjustable resistor. Actually, the electronic load products are generally made ​​of a combination of multiple electronic components for which parameters are variable and can be controlled. Generally, it has a variety of load power consumption modes, such as constant resistance, constant current, constant voltage, constant power and so on.

How to use the electronic load? In fact, almost all the test of power products require the use of electronic loads, despite using a simple fixed resistor can test the specified power and do the aging test, but it is necessary to ready several electronic loads operating in different mode when doing the integrity parameters test for the power product. Because it can simulate a load which the parameters can make any change, and then you can test the performance of power supply in a variety of normal state and limit state. As batteries are also power supply, it is also inevitably to specify the discharge parameters for battery discharge and discharge test in case of damage the battery, such as constant current discharge, constant power discharge, fixed discharge, fixed time discharge, over-voltage stop automatically and so on. Of course it requires the conditional trigger functions of  electronic load, such as the timing trigger, the cumulative value trigger, the threshold parameters trigger and so on.
