Editor's Notes

December 06, 2018: For a relatively complicated category, the things that make a given model superior are simple: total watts, adjustability, and clean output. Models designed for laboratory use, like the two Korad units on our list or the Rigol DP832, are going to be the best options here, though some designed for hobbyists can get away with a little more noise in the signal and still be great investments.
