The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.
What else can I help you with?
Can a 5 volt. 1500 ma. power adapter be used to run a 4.5 volt appliance?
No, get a matching transformer and check the polarity and the milliamps.
How do you convert your 110 volt neon sign to run off 240 volt UK socket?
What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.
Do you need a step down transformer to run a 208 volt steam table on 240 volt feed?
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
Can you run a 4.3v device with a 5v power adapter?
It is generally safe to run a 4.3V device with a 5V power adapter, as the device should only draw the amount of voltage it is designed for. However, there is a slight risk of damaging the device if the voltage is consistently higher than the recommended level.
Can a 12 volt light be run on a 120 vac timer switch?
No and yes. A 120-volt plug-in timer connects the line voltage to the timer and to the switch that is operated by the timer, so you can't use it directly for a 12-volt light.However, if you use the timer to supply power to a step-down transformer, you can run a 12-volt light off the transformer (that's how most low-voltage landscape lighting timers work). If you don't need much current, you could even plug a 12-volt AC adapter "wall wart" into the timer. Otherwise, you would have to open the timer and modify it so that the micro switch is completely isolated from the 120-volt supply and bring it out to connectors for a 12-volt supply. Make sure you know what you're doing and also don't exceed the current capacity of the switch.
Can a 5 volt. 1500 ma. power adapter be used to run a 4.5 volt appliance?
No, get a matching transformer and check the polarity and the milliamps.
Can you use a 15 volt dc adapter to run a 12 volt portable DVD player The adapter in question lists as a class 2 transformer if that makes any difference?
No. You should use the adapter specified for the DVD player. Using the wrong adapter can damage the DVD player and/or the adapter and/or cause a fire.

Can you plug a 110 volt air conditioner into a 250 volt outlet using some kind of adapter?
Yes you can - with a transformer. Maplin Electronics sell a converter that allows you to plug appliances that run on 110V into the normal UK mains. See the related.
Can I use 12V DC output universal ACDC adaptor with equipment that uses AC adapter 12VAC 2A?
There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.
How do you get a 380 volt 3 phase motor to run on a 220 volt 3 phase power source?
Use a transformer.
Can you run a 12 volt ac water pump with a 12 volt dc adapter?
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
Can you run 12 volt equipment on 24 volt power?
No! You would damage it beyond repair.
Do you need a step down transformer to run a 208 volt steam table on 240 volt feed?
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
Can you buy an adaptor to run 120 volt appliance on 240 volts?
Yes, but you are limited to the amount of current draw the 120 volt load can apply to the adapter.
