Re: DC Power Supplies

["Robert W. Harris" <rwharris@CATH-MEM.ORG>]

I've had a lot of different models in various schools.  IMHO the best were
put out by Lab-Volt.  They were variable ac/dc.  They had models which could
be permanently built into the desk, others which were portable.  There was a
key switch, a circuit breaker, no internal meter in the models I had.  These
units were just about bullet-proof; perfect for the H.S. lab.   I don't know
the price, but I'd guess they were worth it.  Much better than most other
supplies I've had over the years.

Lab Volt     1-800-223-1057         No, I don't have stock in the company.

Good luck.  --If you find something better and cheaper, let me know.

want some variable supplies for the student stations with maximimum outputs
somewhere around 12V and 5A. Internal meters would be nice, but not
necessary.

more and 20A or more. I really would like internal meters on this one.
