I am building my first lab and I think I will need a power supply. Was wondering if I can run my thinking through you guys and maybe ask a few questions, please!
1. Variable DC power supply - Budget: under £200.
I am pretty sure I'll need this. I've already looked at some circuits that require 24v.
So, I think a 0-30v supply should serve me well.
a. Do I want a linear or switching? I must say I like the idea of linear being "less noise", in case I want to do anything really sensitive
But finding a linear one without going to fully professional stuff ($$$$) seems impossible!
Is it possible that I could just put more money on a quality switching DC supply and end up with a noise level comparable or better than a cheap linear one?
b. Any product recommendations?
2. Fixed DC power supply - Budget: under £100
Most of the voltages I need are 5v, 3.3v and 12v - which an ATX power supply will provide at a pretty high standard (if it's good for a 7-Billion-Transistor CPU, it's good for my stupid 8 bit stuff).
I also like that a power supply based on an ATX box, will have a few channels. I could run something that needs 12v alongside something that needs 5v.
a. Is there a commercial product that offers a similar solution (3-channel=3.3,5&12, fixed power supply), or is this requirement not so interesting in the real world and I'll be looking to convert an ATX one?
