Question 1

Is this a current-limiting power supply?

Accepted Answer

Yes, I believe it is. Although I've only used it twice. I suggest you go online and look for a YouTube video explaining how it works. It's very informative. Good luck.

Question 2

Can you stack these so you can get a negative voltage for OP amps? IE. Connect positive on unit 2 to negative of unit 1 and take that as ground. Then use the Neg of unit1 for negative voltage and positive output of unit 1 for positive voltage?

Accepted Answer

Yes, the (+) and (-) terminals are floating. You could even connect the common terminal to GND unless of course you want the Op Amp circuit to float as well.

Question 3

Is this a switching or linear power supply?

Accepted Answer

It is a switching supply.  Much less weight than a linear supply.  Note that is does take a couple seconds to stabilize on a new value because of this.  It seems to be relatively stable (± 0.1V) after setpoint is reached.
