Variable regulated DC supply??

[sotto]

Can anyone suggest an economical but good quality adjustable DC power supply, preferably with built in meter?

Thanks.

Hello,

Did you mean to build one up yourself or buy
one already built?

MrAl: To buy, not build. And thanks Ted the Led, the link was what I had in mind, just not quite than pricey.

Hmmm, paid a buck and a quarter for mine -- we have dat2zip to thank for this link:

I've got to appologize for that info. I bought that supply and it turns out to be a POS. Sorry, it's a loser.

For the feature set shown, expect to pay a little more for a real power supply.

Mr. Bulk. I'm very sorry and hope you did not buy one.

I returned mine, got another and it does the same thing. ALmost tossed in the garbage can. It's sitting in the corner now gathering dust.

Oh no! I did buy one, just never got around to using it yet because I don't have a bunch of 5w to test yet.

Tell us what's wrong with it...what does it do that's bad?

most of those china cheapies have poor soldering.
like mfj,tennma,mg,pyramid,tenna,radioshack ect.
folks around here buy them because they are cheap.
i see most of them before the 90 days is up because of the cost to ship.both ways.
if yours is out of warrenty open it up and look for bad solder joints.bet you find a bunch!

the one I got from elexp. is from Korea and seems to be very well made..I'd buy it again, but with the digital readout instead of the analog needle meter ..

 

[MR Bulk]

Oh, man, what a way to start Thanksgiving...without even opening the box yet I already have a nice $124 doorstop...wonder if they take returns this late...

this one works great. I recommend the EZ Digital Co. model GP4303A., about $185.-.. I'm new to power supplies, but it is easy to ' tune it in' to a battery pack's voltage for charging, even if you don't know the voltage; just crank it up till the current flows, indicated by a click, an LED,
and an indication on the current meter -- I still get a kick out of using it..

The two I got fold over and lock up. It's fault load protection trips all the time. Can't get around it. Constant current can never be achieved since it locks out first before going to constant current. It sucks. I want to go in and remove that relay or lockout feature somehow. If that was done, the supply might actually be useable.

I hook one of my modules up at 3V and it locks up. Shuts down in fault protection mode. That's stupid since I have the current cranked all the way up and I need less than a 1/2 A to kick start.
