Do you know what the polarity is for the power supply connector? For use with an AC adapter for example?

Not sure off top of my head. Normally I use a voltmeter to check these things. Properly designed circuits will have a blocking diode to prevent polarity reversal issues. Those that don't, may have smoke issues!

I would make sure the receptacle is working right and is wired and polarity is correct. Dennis

Thought of something else. Make sure your power adapter is set to the correct polarity + -, mine is set at +

The center post is NEGATIVE, the outer shell is POSITIVE. This is opposite of what many common connectors for power supplies have. You need to look on the Casio specifications for the AD-5. Also, there is a small diagram on the plastic case of my CT-700, where the AD-5 plugs into the keyboard, that shows this polarity requirement. Jay Daugherty is incorrect.

Printed/etched on the bottom of the charging base station:"Type:3715100-130v AC ~50-60 H2/2W"If that means it is incompatible, are there adapters / power converters you are accustomed to using for appliances without local native compatibilty?

I have a question can you change polarity coming to the device and how will it affect the power coming out my application is 12 volts into the device and ?? out also what kind of speed control can I expect

According to the manual, the AC/DC adapter should be 4.5 V, 150 mA, center pin negative. Be careful of what power supply you buy. Some do not hold a constant voltage or current.

The small details on the back simply show AP-10-12V. Not sure what that means but I'd be on the safe side and use a power adapter. Don't wanna burn out this baby

I just checked it. Two prong plug - polarized with one prong being slightly larger. Standard plug for US will accept it.

You have to look near socket on device, or on original AC Adapter. On the Velleman PS, it's clear how to connect adapters for center positive, etc.

Not sure about that as mine is negative ground. That said, it should be ground polarity insensitive by reversing the connections.

I go by the model numbers on the back of the old power supply, run that number in Google. Power Plug into the Laptop should then match, and then I like to match up the specs that should be close to the model number ... like how many amps and volts and such. Until my new one arrived I was running a Dell adaptor that came up a little short on Amps but worked because I did not have the battery in the laptop and so it ran a little warm, but was OK. Just match up info on back adaptor you are trying to replace and that should match you up fine. Plug should show polarity on the back, like center being (+) or (-) and such, that should all match up with identical model number just fine.

I'm presuming any 12dc 1 amp adapter would work. Just make sure of the polarity. Go to a local electronics store with the old adapter and say you need a new one of these. They should be able to match it up. Does it work with the DC adapter for the accessory plug? Make sure it's not the monitor that's bad

It could. The distance of the center post may or may not get you to the outside contact of the power supply when you plug it in to the laptop. And make sure you know what polarity goes to what post.

Make sure the polarity is correct. The negative pin -- Is marked on backside.

Yes, but be sure you have it wired with the correct polarity- see Joe K.'s response.

There is a port for an AC adapter. Mine did not come with one. Radio Shack should be able match one if you bring it with you to the store. The polarity has to be correct.
