I had issues with the noise from an SMPS (incl. radiated noise), I'd suggest get a linear power supply first. Note that at least some of linear power supplies don't have good filtering from mains noise, but at least they don't produce much of own noise. Also aim at least for two channels or more.
So, I'd suggest write down your needs first, then come from requirements. Right now I feel like it's an emotional purchase -- you found something that you like, and now trying to justify it . That's no problem as long as you conscious about it. This power supply looks very niche for (rare?) occasions when one needs a lot of current.
Not really emotional. I found something I need from the "free" program and this is the first one offered since I joined the program over 8 months ago. I could die of old age waiting for another - lol. Also, a linear PSU was not offered. It was either this one, or zero. Adding to the deal is that sometimes the program doesn't have a large stock of these "free" items. if you sit around thinking about it too much, you miss the opportunity. Then you cry.
If this one didn't pass the community smell test, I'd just pass over it. It would be nice if it had two channels
(Forgot about that), but I would probably rarely need that anyway.
If there is a way to test it for noise, I'm game. I can always request that it be taken off my tax report for deficiencies (they always take items off and never question it).
As posted in another reply, I'm just going to use to to test computer stuff, like fans, leds lights, and things like that for amperage draw, mainly. I'm not using it for anything permanent.
They also have a 5A version that is $20.00 less. I figured the 10A version wold be a better choice for the extra overhead if I ever needed it.
I think if no one really has anything bad to say about it, I'll pull the trigger on it.
