AC/DC Power Adapters
AC/DC adapters are used for the conversion of AC power to DC power. They will convert 110/220 or 220/240 volts into 1.5, 3, 4.5, 6, 7.5, 9, 12 volts DC output. These universal AC/DC adapters can be used for worldwide travel for products like digital cameras, CD players, radios, tape players, shavers or any other DC powered item.

These are power supplies that convert an AC voltage to one DC output voltage.
If you're replacing an existing power adapter:
-
Choose an adapter matched as closely as possible to the original adapter's voltage and current specifications.
-
Determine the required adapter DC output plug size and polarity. There are many possible sizes.
-
The DC output connector at the end of the cord can be changed or removed if necessary, but if you do this, the adapter can't be returned to the store.
When choosing an unknown power adapter for your own application:
-
Determine the power requirements (voltage and current needs) of your load device or circuit.
-
Select a power adapter with a voltage and current rating that matches the load requirements as closely as possible.
-
The maximum current requirements of the load should not exceed the maximum current rating of the power adapter.
-
A power adapter that can provide more current than the load requires will sometimes work, but if the current difference is very large (say 30 to 50%) be aware that "ripple voltage" on the adapter output may be higher than ideal, and a filtering capacitor may be required to smooth out the DC output voltage of the adapter.
-
Care should be take to ensure that the maximum input voltage of the load device is not exceeded.
