Re: Who makes a high quality power supply?




I think you're taking a fatalist attitude. I have to disagree with you on
a few points. Experimenters need a PS with constant current or current
limiting capabilities (in case the breadboarded circuit is miswired or
designed improperly). Metering is another necessity for experimenters.
Yes, the user can always use bench meters for that, but it's sure handy to
have those meters built into the PS. Keeps everything neat and easy to
monitor, and frees your bench meters for probing the circuit..
Also, as a general rule, I like linear supplies for analog experimenting.
Switchers can cause tremors in analog circuits that will drive you crazy
unless you are aware of the source. Dual tracking supplies are great for
analog circuits as well, since many designs need positive and negative
sources. Again, keeps everything neat and easy to monitor.
People aren't "crazy" for paying reasonable prices for good equipment.
The extra cost of a well featured power supply can easily pay for itself
by avoiding destruction of expensive components because the power supply
couldn't limit or control the output current. Good power supplies don't
become obsolete in a couple of years, as computers do. With proper use
and a little care, they can last for decades.



Someone once told me, "buy good tools and only cry once" and I've found that
to be consistantly true. Not once have I looked back and thought dang, I
should have spent less money on this tool, but many times I've grumbled that
I should have bit the bullet and splurged on a better one.
