This universal AC adapter converts 110 AC to 3, 4.5, 6, 7.5, 9 and 12 volts DC. Power electronics devices requiring 1700mA of current or less
Now, I looked at my failed original DVD power adapter and it says the following:
INPUT: 100-240V~50/60Hz 1.5A Max
Output: +9.5V --- 3A
Will this new universal AC adapter work?
Quick answer... No.
New walwart..devices requiring 1700mA of current or less=1.7Amps
old walwart ... +9.5V --- 3Amps
As stated, not enough current, Your DVD is probably not going to need a total 3 amps, probably more than 2 and less than 2.75.
walwarts give an output in volts and amps
The volts depend on the amps drawn. They inter react. unless you get one with regulation.
In other words. if'n you had one that said 9.5volts and 5 amps output and your player only needed 2 amps then the voltage would be much higher than 9.5 volts and may damage the player .
I do not like universal adapters. they are dangerous to devices as they require significant knowledge by the user and most people have no idea.
1./ The multiple voltages are just asking for trouble, either on purpose or by accidentally moving the slider position.
2./ Some of them accommodate polarity reversal. Center pin either positive or negative.
3./ The voltage settings are irrelevant. As stated above the voltage output is dependent on current drawn by the device.
Again, if it has regulation, you can ignore #3, To determine if it has regulation, plug it in and measure the output voltage with a meter, if it is several volts higher than stamped on the unit, it most likely is not regulated.
I have seen many a universal adapter that has damaged many a devices.
Now if you can look at your player and determine the current rating is less than 1.7amp then you may be able to use this universal adapter.
Say the player wanted 1.5 amps, then the voltage would be slightly higher than the 9volts indicated. If it draws 1.0 amps then the voltage may be 10 to 11 volts. Get the picture?
However, once I determined the load and correct voltage position I would seal the slide switch with silicone or something to keep some idjit from fiddling around with it and once you have determined the correct plug polarity then tape up and/or glue that as well.
Unless your original has a switch for 110 or 220 v I would guess that it is a regulated supply. If you know someone that can crack it open and has some electronic know how then it may be salvageable.
