I'm currently using a Mastek 1803D (Adjustable Voltage and Current 0-18VDC, 0-3A). When I need an additional voltage I've been breaking out an LM317+Wall Wart supply I got started with. I'd like to move up to something with at least one output good for 30+VDC/5+A and more outputs, preferably adjustable. All that and I'd like to stay under ~$200.
The driver behind this is working with a combination of 3.3V, 5V, and Motors (and I foresee 1.8V eventually being needed to). I deal with it now using linear regulators but I'd like to have the bench supply handle it all.
So, background out of the way, what would folks recommend? I'm open to a do it all unit, or maybe buying 2 more single supply units and tying all the grounds together. The current limiting features seem to rule out most DIY/ATX Power supply approaches, maybe use those for the fixed voltages and tying it with a standalone? Should I be going with a fixed output supply for the primaries? (I've found lots of 3 supply 5/12/Variable units but no 3.3/5/Variable).
Thoughts? (Thanks in advance.)
