How do you convert 480v to 120v?

Answer 1

to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.

Answer 2

To convert 480V to 120V, you can use a transformer. You would need a step-down transformer that can reduce the voltage from 480V to 120V. The transformer will have a primary winding designed for connection to the 480V source and a secondary winding for the 120V output.

Answer 3

The way the question is stated this type of a transformer is a step up transformer. A voltage of 120 volts is applied to the primary side of the transformer and the 230 load is connected to the secondary side of the transformer. Since you also used the category Pool Heating, the transformer must be used in the control unit of the pool heating controls.

The other option is that the transformer is a step down transformer 230 to 120 volts and is used for 120 volt control voltage, the primary is then connected to the 230 volts. In the control unit, the transformer will probably be connected to the supply 230 volts circuit from the heater circuit. There should be an in line fuse between the incoming 230 volts and the primary connection to the control transformer. The fuse should be rated at 1/2 amp for proper protection.

Answer 4

To convert 480 to 120 a transformer will have to be used. The transformer needs to be the right voltage and amp rating to handle the load that will be connected on the 120 side.
