Great psu for pelts and how to mod it

killersushi · 03-10-2002, 07:08 AM

I have found a great power supply for running all sorts of pelts. I've wrote a guide on how to mod it to run 24V specced pelts as well. Check it out if you're into it:

your site is down for me....

killersushi · 03-10-2002, 01:07 PM

I noticed, little crappy today. Right now it works, just try again.

EMC2 · 03-10-2002, 04:20 PM

FYI - as long as you don't want to go over 15V, there are a ton of good, inexpensive PSUs out there, all of which are done for HAM radio.

Under $200 you can get adjustable ones with analog meters all the way up to 45 Amps. Under $130 you can get up to the mid 20 Amp range.

If you go to a local HAM swap meet, you can find them even cheaper

Most of the switcher based units can be V-Modded as well

killersushi · 03-11-2002, 02:23 AM

EMC2, can you show us a psu that can be modded to serve 0-19.5V adjustable with 40A output for $160 or less?

Brad · 03-11-2002, 02:41 AM

http://www.mpja.com/product.asp?product=12844+PS

4 of those in series would give you 21.6v @ 60a (using the 5.4v @ 60a line) and you still have another 22.24v line @ 25a, and 4x 12v 6a

and only $40, $160 will give you a psu capable of powering like 6 172w pelts. And if you buy 3, you have 15v only, and can run 4 226w pelts

killersushi · 03-11-2002, 03:05 AM

I was thinking of ONE psu, that can also be fitted into a case, not 3 or 4 in series. Your example is not fine-adjustable to get the best performance for your pelt setup, either. And it's not exactly user-friendly

I'm aware that people in this forum are the most pro guys in pelt cooling, I was expecting the most resistance here because you people know how to help yourselves, and that's great. I thought I would post the link here anyway. It's fun

Brad · 03-11-2002, 03:41 AM

no doubt about that, your link is excellent, and I'm sure it'll help a lot of people, but for the price it just doesn't give me what I'd like. The setup I linked to would power absolutely anything, and wouldn't be too hard to setup (probably easier than soldering on the psu board

EMC2 · 03-11-2002, 09:22 AM

Here in the states, 0-15, 40A, < $160, single supply, fit in a case? Not without digging around.

Here are some representative supplies easily found here

These are store prices in US $, at HAM swap meets you can usually get em for 10-15% less, more if you're patient (got one PS at a %50 discount one time because the guy said it put too much noise on his HF rig and he thought it was a worthless noisy supply

). All the below have voltage and current meters, all brand new, operation out of the box unmodded.

5-15V 30A, $139 Alinco DM-330MVT ( my personal fave, you can get it here, search the radio/power supply area) and here is a nice picture of this baby )

9-15V 40A, $180 MFJ MFJ-4245MV

You can get Pyramid units even cheaper, but their out of the box 12-15V ranged and don't use the same quality of parts as Alinco and MFJ units.
Pyarmid PS52KX runs in the $160 range and is 46A, PS46KX runs in the $140 range and is 40A, PS36KX in the $120 range and is 31A (all constant rated power).

The unit on your link isn't sold in the states (at least not under those brand names). That being said, the comment was NOT anything against your article, in fact it was quite good

It was simply a point of info for people. I've been using HAM swap meets for years to get inexpensive high current supplies for electronic projects. It's an area a lot of computer hobbyists don't think about as a resource for them. And if you don't care for the voltage/amp meters on them, there are quite a few models that can be had for $30 to $40 less (never understood why they charge so much for meters on them).

killersushi · 03-11-2002, 09:34 AM

Interesting info there. What about power supplies for running 24V pelts? Like with 18V output or something? And finally, how about the ultimate all in one thingy that I dream of (basically what drove me into writing this article), that can run them ALL, 0-18V with at least 40A of output?

EMC2 · 03-12-2002, 05:09 PM

All the HAM power supplies I'm familiar with are only adjustable to 15V out of the box. However, any of the newer switcher supplies are Vmoddable, just like the one in your article to go higher (within limits). 18V should be easily attainable with 90% of the switchers. Just be sure it isn't a linear power supply

As far as the low end, why would you want to go below 5V, short of turning it off completely ?

killersushi · 03-12-2002, 05:41 PM

Nah of course, forget about the low end. Let's say 10-18V 40A+ then. Ok thanks for the info. These ham thingies seem to be hard to get here in Europe, it seems.

EMC2 · 03-12-2002, 06:55 PM

See if you can find a Euro based web sight for HAM operators. They'll be able to point you to Euro sources for equipment.
