Building an adjustable constant current load
Here’s a project log covering the build of an adjustable constant current load. It’s capable of sinking up to 7A, and can withstand input voltages up to 60V. The log covers the design, perfboard assembly, and case assembly.
An adjustable power load is a piece of test equipment that often comes handy in the development of a certain electronics projects. For example, when you are building a power supply, it will come a time when you need to “simulate” a load to see how well your design performs as the load varies. Adding power resistors to the output can sometimes do in a pinch, but often you will not have the right resistor value handy with the right power rating for the test. This is where an adjustable electronic load comes handy. In this article, I’ll show how you can build one using common components available to the electronics hobbyist.
