Benchtop power supply recommendations

A

amerdsp

Can anyone recommend/suggest a good and affordable benchtop power
supply that is suitable for developing embedded applications? This is
for a home lab with limited budget.

Sure... so how do I know that's not some sort of multi pop-up pron site that
will get logged by the company and seriously waste my promotion prospects?

Yeah, he misspelled it... it's actually tinygurl.com.

Is that better than alt.binaries.pictures.erotica.midgets?

Thanks for all the replies. I searched online before posting, but I do
not know what is good quality and reliable. I looked at places like
digikey, jameco and mouser. There is also mpja.com, but I was not
encouraged by some of the reviews about them. Are there other places
for electronic parts and equipment?

Thanks again.

Who. 5 hours left for an 8$ power supply, a real beauty.

Extech makes a lot of nice stuff. I've got some of their things (ir
temperature gadget, air flow meter, sound level meter, whatever) and
they all seem fine.

AADE's L-C meter is cool.

Buy a Fluke DVM... they're very reliable.

Well, yeah. You could try the local Radio Shack. The web site is, ahem,
not very useful and the stores seem to shrink but maybe you find one
that has some bench supplies.

Important: Always mind that the series transistor in any bench supply
can short out and that it won't announce anything before it does. This
sends the full rectified transformer voltage to the circuit which
usually destroys it quite completely. What I do when I have really
expensive stuff hanging on it or a one-of-a-kind client prototype: I
place a resistor in series and a zener across, plus sometimes a fuse.

Hello John,

The price isn't bad at all. But the enclosure? Oh man, now this designer
stuff starts to encroach into electronics design. Does the LCD backlight
flash in rainbow colors? I vote for keeping things utilitarian like it
used to be. Then fanciness level shouldn't exceed that of HP gear.

Lascar makes interesting stuff such as USB stick data loggers etc. And
the lady who answers when you call has that nice rightpondian accent.
Their panel meter I needed more specs for wasn't a "meet'r" but a "meetah".

I had that reaction at first, but I kinda like it now. It has a nice
feel. And after just pulling an ugly grey HP608 RF signal generator
off a high shelf (my back should be OK in a few weeks) I sorta like
cute little instruments.

Incidentally, the power supply is a switcher.

Some of their DPMs are cute little round buttons. Neat designs.

Say, we could use a new RF signal generator: < 5 MHz to > 1 or maybe 2
GHz, low phase noise, no fancy modulation, just need a clean sine
wave. Any suggestions? We'd probably buy used to get the best
performance per buck, unless something radical has just been
introduced.

It looks like it belongs on the dashboard of a sports car or motorcycle.

Does the curvature of the enclosure keep it from being stackable?

Go see if "Halted" still has some of those Zantrex supplies on hand. No
paperwork and no power cord is a small price to pay for the deal.

Just checked: they stack nicely. They also have little flip-out bails
on the bottom, in the front, and a sticky silicone strip on the bottom
to reduce tendencies to slide around the workbench. This is seriously
good design.

The country preacher is preaching fire-and-brimstone about the alleged
bestiality going on in the community. "There's people having sex with
Sheep! With Pigs! With Chickens!" and a horrified voice from the back of
the congregation cries out, "Chickens??!?!?!?!?????"
