Dell power supply ADP-220AB B output schematic

How can I find out about the correct voltage at the Dell AC/DC Adapter utput plug that has 8 contacts? Brochure indicates the power output is 14v but I measure only 7.3 volts at one of the 3 plugs amongs those 8 plugs.

Thanks in advance for your help.

    Specific input voltages for this adapter are from 100 to 240 volts and output is 12 volts. I believe that the output should be 12 volts either at 120 volts or 240 volts, but I only got 7.4 volts. Do you think my adapter is defective?

It may be possible that your adapter does not receive the rated power it should receive. You may have plugged your adapter to a 110 v outlet when the required input is 220 volts. See your adapter for the specific requirements.

What is the power output of ac dc adapter in jensen jta 460? Can this adaptor be changed with 220volt ac dc adapter with required dc output?


For Any Adapter:
As long as the Voltage and Power output of the power supply (wall outlet or other) matches the input requirements for the adapter whether 110V or 220V.at enough amp output; and
IFF the dc output of the adapter is exactly the same voltage and has for amps at a minimum matches the maximum amperage requirement for the input of the device, any of them will work, as long as it has the right connector with the correct polarity needed for the device!

Or, in other words...

Supply Output V = Adapter Input V
and
Adapter Output V = Device V
Adapter Output A(min) >= Device A(max)

How do I get my computer to recognized my new ac power adapter?


The computer doesn't need any drivers to recognize an AC Adapter. If you have purchased the correct AC Adapter for your laptop then it should just work when you plug it in. If it does not then my guess is either you have received a faulty AC Adapter or the DC Jack which you plug into in the back of the laptop is bad.
I am assuming your battery is dead and when you plug it in and turn it on nothing happens?
You can also try taking the battery out and try to power it on with the AC Adapter plugged in.

The Dell Latitude D610 takes a PA-10 or PA12 AC Adapter. It's 65W or 90W

For 90 watt Adapter the output voltage on your AC Adapter label should read 19.5V and 4.62A
At least that's what the Dell brand reads so it should be close to that.

I have lost the original power supply for my dell 1701fp monitor. I have a power supply that I think may work as a substitute until I can replace the original. I need to know, what the acceptable voltage...


What ever you use, it must be REGULATED power supply that will maintain 14vdc output, rating at 3A. These regulated power supply can easily maintain the output voltage within +/- 5% with input AC voltage range from 100~240vac.
Linear regulator power supply may not work since it has slow response time to regulate the voltage.

Use Sony ICF-C1IPMK2 in Europe


A transformer type (Linear Mode Power Supply) AC to DC power adapter with a 9.V nominal output, measures about 12.V without load when tested with a multimeter. A power adapter with a nominal output of 7.5 V, measures a little over 9.V. Considering a number of people across different forums reported the adapter's measured power output as 12.V, I think the nominal rating of the AC to DC adapter should be 9.V. However, keep away from Switch Mode Power Supplies.
