So, I have decided to purchase a new bench power supply to complement my existing finely handcrafted model (cheap Elenco kit). I'm looking for a digital one with some bells and whistles, but I have a question since I am fairly new to this sort of thing. Don't worry though - the question isn't "what should I buy?" Hopefully, it isn't a dumb question.
My question is: on the power supplies with separate controls and displays for voltage and current, is it safe to assume that the current display will show the current being drawn, or is that a feature on only high end models? If it is the latter, what key words should I look for in product descriptions that would indicate the presence of an ammeter function?
Essentially, I'm thinking that feature is so useful, I would pay a premium for it, and conversely, I would be sad of what I bought did not have it.
Thanks!
