im not sure, but this charger works exactly the same as the original charger that I lost. im assuming it will most likely worj for you.

I'm not sure what the polarity is but there is no option to reverse it on this device.

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.

Hello! My name is Juan. I called Dell to try to get an answer for you but all I got was the run around. If you're sure that all the specs are correct you may try this adapter and see if it works. I just recently found an adapter for my sons Acer in the same way. Please do make sure that even if the specs are correct that the polarity is also correct. If the polarity is inverted it will burn your computer or the charger. If anything I did get a link from dell to their list of chargers and compatibility. Here it is. I wish you luck in your search. http://accessories.us.dell.com/sna/category.aspx?category_id=7683&c=us&l=en&s=dhs&cs=19&mfgpid=167691&chassisid=8499&Tab=Parts&stype=2

The voltage is 9 v and the amperage is 80 mA. the polarity is Neg-outside and Pos in the inside.Neg---(0---Pos.

Sorry, but I don't remember. Mine was used with a 12v DC converter for a light strip, so polarity is a definite concern

Make sure the wiring polarity is correct... I had mine reversed by accident at first, and it didn't work (plus the power wire almost immediately heated up).

If you switch the input polarity the unit will not function at all. It has a diode. The unit will not light up. It will not turn on. It will not work. DC polarity must be connected as shown on diagram. Can you tell me why you wanted to change there polarity?

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.

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.

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

anyone with the adapter, can you help? I need to know if the tip is center-positive? thank you for your time!

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

yes it's true, it has no polarity on both terminals. either ways of connections work properly.

You can plug it in either way, it is not polarity sensitive. You can not go wrong with this ths night light. We use them several places in our home. We found them once when we were staying at a strange/new/different location while traveling and really liked them and have bought 4 of them fof at home use, as well as, when traveling.

i believe the two black are the heater 12v no polarity. the other two are signal to the computer and polarity is necessary. good luck. peter

Sorry, not so technical, so here are all the details those I can see. On the adapter, there is a small switch than can move from right to left, and on one side it shows 120V and the other side shows 240V. Further it shows as Input: 120V/240V AC 60/50Hz....hope these answer you question.
