Did I ruin my machine?

[Eddie]

3 choices:

1. A video of NYC going dark.
2. A video of a nice pachinko machine working properly.
3. A video of a sad man crying.

I'll go with #2!

#1 would have been cool!!!

Dude, that was an entertaining video. I stopped watching one of my favorite TV shows to view it. Kind of sad on my part.

Congrats on the debug and fix!! Can't wait to see vids of the machine, it's a beauty.

Im honored!!! Thx

I hope nothing else got cooked.

Eddie, stop plugging that thing into 100 volts, it's 24 volts...use the transformer.

[arbycoffee]

Always asume 24volt than work up to 1200volt:whine:

[fronzdan]

I think rollercoaster is the only one who ever had a machine that ran on 1200 volts.

Last transformer question.

The 24v transformer that I hooked up backwards had no markings on it designating input /output. It has 2 set of wires one guage larger then the other.

I just figured that the larger guage wires were for the 110v in and the smaller guage wires for the 24v out.

The question is why is it the other way around?

The batch I sold on Pachitalk had the power cords already attached

it saved a lot of confusion for the buyers

The wire gauge is directly proportional to the current flowing in the wires. As the power at each side of the transformer is equal (allowing a small bit for transformer losses), then the lower voltage side will always need to be able to handle more current.

For example with a 120v input to 24v output transformer. If the output current is 5A, then the transformer power rating is120VA (volts x amps), this means on the input side the current will need to be approximately 1A for the same 120VA power rating.

A wire carrying 5A will need to have 5 times the cross sectional area than a wire carrying 1A.


Don't get confused with the overall diameter though, as when the voltage on each side of the transformer is significantly different, then there may need to be more insulation on the higher voltage wires, making them look larger than the low voltage wires.

OK... in it's simplest terms...
Let's assume the transformer is 'perfect', and has 'unity coupling'. In other words, power in = power out.
(Ignore loss due to heat, eddy currents, etc.)

Now, a typical 24 volt transformer here in the US has a 5 to 1 ratio, step-down.
In other words, 120v in gives 24v out. (120:24 = 5:1)
Power will be maintained, so although there is a step-DOWN of the voltage, there is a step-UP of the current capability. (Power remains the same, and with power being voltage * current (Watt's Law), one will rise when the other falls... they are inversely proportional)

So... now assume for a moment 1 amp of current in the input (120v) side. There would be 5 amps (capable) in the output.

Although the voltage on the secondary would be lower, the current would be higher.

AND... the higher the current, the higher gauge wire you'd need.

Of course the current in the primary (input) would depend on the needs and draw of the secondary (output).

Yeah... simplest terms... right!

DOH!
Daverob beat me to it!

buy your transformers from Gaku and you will get a beefy high amp one with the power cord attached already

This might help you a bit better think of the transformer as a scale you know the transformer is rated at 5 amp at 24 volt output to the machine . Now know that wattage is = to amps X volts so your transformer is rated at 120 watts (5 amp X 24 volts) on the secondary or output side to the machine. Now we need to balance the scale on the other side so we take the 120 watts and divide it by the voltage in to the transformer of 110 volt at most residences in the usa and we get a total possible current draw of 1.09 amps (120watt divided by 110v ). now since we use wire based on amp draw you can now see why the input wiring is smaller 1.09 amp (primary side )to the(secondary) output sides 5.0 amp output needing the larger size wiring .Incidentally this is why its allot easier to send power to your home from the power company at 15,000 volts instead of 120 volt . they can send it at a lower amperage using smaller wiring (cheaper than large ones) and step it down using transformers (higher cost but a lot cheaper than thousands of miles of larger size cables)and allow you to use it at a larger amperage at 110 not to mention the voltage drop of sending power miles away from the source would drop it to below the usable voltage limits.

Simplest terms: Because I said so !!

[alstonj1]

or what he said

[compirate]

Best thing: buy a voltmeter and test it before hooking it up if it isn't labeled.

I have one but was in too much of a rush to dig it out.

In other words I screwed up!

[dattia]

Well Eddie, that is just a testament to how much you love these machines. You still have the excitement of a child with each new one...and I think that is great!

Been there, done that, probably will do it again!

[arbycoffee]

Eddie I have a frame found, but need to see the hinge hook ups on your machine.

Man, if you'd only waited, you could have gotten the whole machine for only 32,780Y!

Y'know Dave... I never woulda’ thought it, but I have been using these x-formers for a while, and although confused to see the smaller diameter as the 110V source: These have all worked fine. Just doesn't seem "right" that the smaller diameter wire goes to the wall

but... there it is !
