A transformer is needed to convert 110 v to 220 v or vice versa. This type of transformer is commonly used in Europe for power tools in the building trade which run from a portable 110 v transformer with a centre-tapped earth for safety so that each side is only 55 v to earth. A 3 kVA transformer for this purpose costs about £80.

Apple computer can run on 220V from 110V power supply?

No, of course not. The power supply needs to match the 'wall power' to provide the proper voltages to the motherboard. On the bright side, most power supplies sold in the US have a slide switch to select between 110/220 volts input. It may be as simple as moving a little red switch on the back of the power supply to configure your power supply to 110 v.


What does a power supply receive 120 volts of?

ELECTRICITYNote: Some power supplies operate on 120 volts 60 Hz ac but others operate on 230 volts 50 Hz ac.Which voltage your power supply uses depends on which country you are in.For more information see the answers to the Related Questions shown below.


Can you use 5 volts 1.2 amp power supply on 5 volts 3.0 amp device?

No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.

What kind of power does a power supply receive from a wall outlet?

Household electricity is supplied to a pc's power supply module as alternating current (ac).The power supply converts it into direct current (dc) at various voltages - such as +12V , +5V, etc. - which are then delivered to the pc's subsystems.Some power supplies operate on 120 volts 60 Hz ac but others operate on 230 volts 50 Hz ac.Which voltage your power supply uses depends on which country you are in.For more information see the answers to the Related Questions shown below.


Does the back of the power supply have a switch that can be set for 230 volts or 115 volts?

Some power supplies have a voltage selector switch at the back that can be set for either 230 volts or 115 volts depending on the region's power requirements. However, not all power supplies have this feature, and it is important to check the specifications of your specific power supply model to confirm if it has a voltage selector switch.


How do you grade up micro volts to volts which can operate any small devices?

The voltage can be changed by a transformer, but the power remains constant. So if you have a supply of 1 microvolt, it would have to supply 1 million amps to give a power of 1 watt (power = volts times amps).


A power supply receives 120 volts of power from a wall outlet and converts it to?

A power supply receives 120 volts of power from a wall outlet and converts it to a lower voltage output suitable for electronic devices. The conversion process typically involves transforming the voltage using transformers and regulating it with circuits to provide a stable power source for the connected devices.
