I am looking for advice on a power supply to buy for my electronics hobbies. I have been using 9V batteries and unreliable power transformers for a while. I recently started taking some of my electrical engineering coursework with lab work and have found the rack mount power supplies in the lab far more useful even than the oscilloscopes. Just having a reliable power supply makes all the difference. Here are the features I want:
Adjustable dual supply to at least -12V/+12V
Quality product but affordable price, a tool I can be happy using far into the future without spending myself broke
Switched mode? (more expensive but lighter and more efficient, do you recommend linear for me?)
Short circuit and overload protection
Adequate current and power ratings for hobby electronics (I'm sorry this is so vague, I need advice)
I am wondering partly what power supply you recommend I buy, but also what current delivering capabilities my supply might need. Most of my projects are quite low current, well under an amp, but I don't want to hinder myself from projects with higher current demands in the future. I want a tool that will be useful for me for a long time to come. I am investing in my hobby now because if I'm going to buy the right tool, I might as well buy it as soon as possible so you can use it for as long as possible. That is my thinking. I need some info on a few power supplies you recommend and what you believe their advantages and disadvantages might be.
