We've gone over this subject before, but i was asked about power supplies again today and about the best bang for the buck I've found in the past is the VOLTEQ Power Supply HY1520EX 15V by Mastech:


 
From 0-15v at 20 amps should cover about anything a slot enthusiast will run into and at $140, seems like a good deal. Of course, you're not going to be carrying this one around! Anything else out there that'll do these numbers and cost around the same or less???

Thanks for the supply information, John.  For what it does and the price it's about perfect. Plus the fact I just need a supply to sit at home this kind of one/size is perfect. 

 

WIll be picking one up soon. Be intriguing to see if there's anything else that does similar.

[Mr. M]

Call Bill Pinch at theraceway.biz. He sells one that is very inexpensive, small, and has about the same capacity.

 

(321) 600-4951.

I'll have to look up my model, but I found one delivered for $100 that is 30 amp 15 volt variable.  A little smaller than the model above.

 

I don't have time now but I"ll take a pic of it tomorrow and look up the model number! It was the best deal I could find and I just bought it last month I think through Amazon!! FYI.

What power input?

 

240v?

[don.siegel]

I assume these are all 110v for the States, Zip.

 

I haven't found anything similar at these kinds of prices in France, but haven't looked for awhile either... I've still got my old 2 amp variable power supply which works for most stuff, and a 5 amp one for the tire truer and hotter rewinds, but would love to get something like this, especially at that price!

Zip, this selectable either 110/240 with switch at the back. 

Would definitely like the model number of your supply, Tim.   Had a look on Amazon before; obviously hadn't looked hard enough LOL.

I have the 8 amp model and it runs S16C G12 motors fine.

That would be a great deal!

You'll notice this is a very small power supply. Used in Amateur Radio.

That looks like a nice one, Dennis.

[havlicek]

That is a nice one... BUT... power out is 5-16 VDC.  I have a power supply now that starts at 5.5, and it's really handy to have it go lower.  5VDC is a pretty good spin in some motors.  Still, for many it might be fine, although it's more costly at $160.

5v is way too high for a G7 motor, especially at start-up, when the brushes are hardly broken in.

 

Back in my G7 days, I seldom went over 3v on a G7.

[Dennis David]

Understood. This is to power my home track where I use 10-12 volts.

[havlicek]

Understood. This is to power my home track where I use 10-12 volts.

 

Yep. For general use though, it really is best if the supply goes from 0-12+ volts, and can deliver at least 10 amps (and even that might be on the light side).  

 

So far, out of what people have shown, the Mastech still seems to be the winner.

For the Mastech supply, I made leads out of 16 gauge lead wire. I tried smaller ones at first, but they just didn't seem to work well. Made some with 16 gauge and now works like a champ!

[Trevor Neilson]

I just used a old computer power source. It can give you 3.3v, 5.v or 12v at around 20amp. Usually you can pick up  a old computer for free, so the price is right.

[gotboostedvr6]

Computer power supplies can't really handle the abuse our small DC motors will deliver. The power supply of often sees the motor as a straight short and will go into protection mode and turn off.

[havlicek]

If the supply can deliver an honest 20 amps, then it should work.  Still a truly variable supply (0-12 or more volts @ 15-20 amps) is a MUCH better solution for all needs, from running devices like com and tire lathes to the widest variety of motors.

Speaking of Mastech power supplies, this baby got left on my doorstep earlier today, hopefully to let me fine tune the power

to the age/abilities of my various party racers.

 

[havlicek]

I would definitely be interested in your thoughts about the Mastech after using it Mike.

[MSwiss]

I have 4 parties between now and Monday, including a VW car club Sunday night, that's supposed to be about 35 people, so it should get

a good workout.

[redbackspyder]

Try the Pyramid ps26kx..... This will do the trick for powering tracks and doing most any chore, with up to 28 amps available and at around $100

[Gator Bob]

Mike !!!

     That was crazy fun   ... more     Got any old G7s around?

 

 

BTW: IMO these specs are important but not many companies list them like the one Dennis shows.

 

•Ripple Peak-to-Peak Max.
•Noise Peak-to-Peak Max.
