Circuit Specialist Adj Power Supply

Postby HomeRacingWorld » Wed Mar 23, 2016 8:03 pm

I am always looking for new supplies that might be useful for our hobby. The venerable Pyramid we have is still going strong, but when I found this one I had to get it to test it out.

Watch on youtube.com


I purchased mine through their Ebay store for $89.00 Free Shipping. That is a pretty decent price considering these heavy units cost quite a bit to ship.

It met the simple parameters I wanted: Adjustable Voltage with enough amps for 4 lanes. Since we do not use any high amp draw commercial motors, 25 amps is more than enough for 4 lanes.

I like the digital display as it makes it easy for me to check the volts at a glance. I checked the unit with my multimeters and it's as accurate as you can ask for.

Image

It has a fixed switch on back that if you turn it on, it overrides the front panel and delivers 13.8 volts fixed. Leaving it off allows you to use the unit as you would normally.

The one aspect of this supply some of you might like is how QUIET it is. I almost thought it was defective, but the fan unit is just that quiet. The only hook ups on the rear, but that is fine by me. I only purchased it for track power so I don't need any connections up front for bench accessory.

Image

Not much to test really, it simply works. I like the easy to read display and the small footprint took the place of our Pyramid easily.

IMHO this is a very good value. Time will tell of the reliability of course, but for the low cost this is a very attractive model for those looking for a good supply.

Wow, that is a nice find at a good price! Wish I knew about this a couple weeks ago before I bent up the metal shelving for my power supply for my wood oval! This PS measures just under 8 3/4"W x 8 3/4"L x 4 3/8"H...a tad too big for my space. Oh well, will make a great power supply for all scales! I really like that 13.8 v lock switch, that is what I would run my 1/43 cars at, an in between voltage for the recommendations of Carrera and SCX cars on plastic track!!

I had seen this online when I was looking at the solder station that was reviewed on the site. It looked like a value at the price and I liked that the output was on the back side rather than the front. The large meters looked like an added plus to me and I was planning to buy one. I still plan to buy one when I get that far as the one powering the Insane Speedway is on loan from Tom. You just have to love that guy. So at some point I will need to buy one and I plan to get one of these. After all it has all the features I want for a good price and Harry's endorsement. The only it could be any better is if it were free.

Oh man, fresh walls...... I call the spot between the M and the E. Yep I think that's the spot I will mark first.

That looks like a great deal especially with adjustable voltage and a fair amount of amps. If I had nothing I would sure get one.

I use a 9-13 volt supply with 33 amps. I've been using the same one for 4 years or more and bought a second one in case I ever want/need to double the amp output.

It's silent.

After a weekend of running just about everything we could throw at it, this supply shines. Most everyone liked the very quiet operation and the LED display.

For the money, this is a top notch slot car supply and pleased at the results.

Just a little note. After reading your review, there were 5 of us that bought this unit. No complaints here! :music-rockout:

I tell you what. That unit got a serious workout this last week. Specially on Friday and Saturday. We tested it on Saturday with 4 NY Modifieds with 40K motors in them. All running full tilt too. The power supply would spike to about 14 amps, for about 1 second once in a while but pulled 4-6 amps continuously with no complaints.

Top notch.

I too, just purchased this supply. Albeit from their website, so I got hit with a 22.00 shipping charge.

Still the cheapest supply out there for what we're looking to use it for!

Should get here around the 14th.
