Hello all,

It's my first post on this forum, have belonged to others but hopefully their will be someone here who can help.

That's my question:
I've a 32m line scalextric classic track, tha have more than 20 years.
I need to change the old transformer with the same age from a new transformers.
The old transformer is 12volt with 1maph.
I like to know what kind of transformer is the better to my track. I don't know how maney volts nad amph is the best for this kind of track.
Can anyone help

Kind regards
Alejandro

PS: Sorry but my english is not good

Howdy and Welcome,

I am sure someone smarter will likely respond, but, 1 available amp per car would be good for regular plastic 1/32 cars, 12-16volts (16 best as you may want to run modern cars too).

If you are keeping a simple two lane track and want to keep it simple, you could just buy another Scalex power supply and a Classic power track and use both transformers at once. You then have twice the amps (watch someone swat me down on this one! Please do.)

Otherwise, if you are handy you could buy a variable DC power supply and adapt it to your track.

Bienvenido Alejandro.

We aready met in Slotadictos, didn't we?

First, KEEP YOUR OLD TRANSFORMER. Sorry for shouting this, but a lot of people say "OK, it's a 20 years old transformer, I'll get rid and buy a new one" Never mind! Think that new transformers never pump 1 Amper for your car. If voltage is not enough just install a voltage doubler in it and you have a "better than new" transformer.

On the other side, my best recommendation is two identical, stabilized transformers. Use slot PSU, ham radio, or electronics lab; or someone else. Anyone that delivers 1A between 2 and 18 volts will be OK.

Not being that hot with electrics myself (my father was an Electrision, not me!) I am just using 4 x old power supplies from the 80's. 1 for each lane of my 4 lane circuit. This also stops the problem of power surges when one car de-slots.

They all plug into 1 multi plug that has a curciut breaker and power surge guide, in it, that plugs into the mains power. So when I have finished, there is only 1 switch to turn off.


Hope that's of some help, and good luck with your track.

Alexjandro,

I like variable power supplies. They let you change the voltage and this makes your cars more fun. Professor Motor sells a very good power supply. It is 0 to 20 volts and 10 amps maximum. You can find it at this link: http://www.professormotor.com/cat_wiring.shtml

The part number is MGPS10AD.

Will this work?

Cosel R150U-12-N It is a 12-20? (adjustable) volt 13 amp regulated power supply. This is very similar to the Cosel/Elco K150 power supplies The R150 is a thinner design with a smaller heatsink It is small and lightweight considering it's output for it's size. the unit measures 7-1/2 in long by 3-5/8 tall by 2in wide. It is a switching power supply. designed to operate from 100-120 volts ac 50-60hz

dacosta,

I don't know PSU you're talking about, but as far as I can understand from your explanation, sounds a very good one for 1/24 slot cars (Parma, Plafit, etc...) with "ampers-hungry" motors.

It will also work OK for 1/32, but you don't need so much intensity. A PSU with regulable output voltage (2-18v) and 2 or more Ampers will be perfect. Something above these specifications will work.

Nep72,

Thanks for the info. I bought one of these for my R/C chargers...so I thought if it was acceptable I would buy one for the track I'm going to build. I used to run HO scale cars years ago...When I went to the LHS and saw the detail of the 1/32 I was bitten by the bug again.

Again thanks...

Nep72,

Thanks for the info.

But my problem is that the cars go faster in some part of track than in other.
Let me introduce an exaple to undestand the problem:
Suppose that I've a oval circuit, I connect the transformer in one of the straight. When the car pass throw the straight that have the transformer connect the car goes faster but when pass throw the other the car goes slower.

First of all I think that the track doesn't have a good connection contact, but then I tested with a small circuit making of with the best track, and I've got the same problem.

So I thinks that the transformer don't pump the right voltage o amph. A part from that I use one transforme per line.

Anybody could help me??

Regards

Its definately a track problem, not a transformer problem.

If the car gors fast and accelerates by the transformer, then that is not your problem.

Either the connections are losing power the further you get from the transformer, or some of the rails are dirty or warperd, or the rails are catching the guide and slowing the car down in other places.

Clean all the rails and track connectors thoroughly
