Do I have 230V or 115V?

In the United States, Alternating Current (AC Power) is provided in the 120V range. So if you are in the USA, you would use the 115V switch position. Europe and other countries use the 230V range so if you took your computer to one of those location you would have to switch to the 230V setting.

What is the difference between 115 and 230 volt?

A 115 volt circuit is wired with one hot wire that carries the current with one neutral and a ground wire; while 230 volt circuits are wired with two hot wires and a ground. The amp load is split between the two hot wires which provides the somewhat deceptive amp draw on the motor label.

What does 115V 230V mean?

A tool labeled as 115v/230v is equipped with a dual voltage motor. It will come from the factory wired for either 120v OR 240v. To use the other voltage, connections within the motor must be changed.

What is a 230 V?

400 V and 230 V refer to the same lines – 400 V is the designation when it is three phase, 230 V when it is single phase (more on single phase and three phase). These voltages used to be 415 V and 240 V but were reduced to harmonise with Europe.

How do I know if I have 230V?

The voltage reading should be within 10% of the voltage. For example, if the voltmeter reads between 207 and 253 volts, then you know you have a 230V motor.

Can I plug a 230V into 110v?

Plugging a 220v device into a 110v outlet is not recommended. If you did, it’s highly likely that you’ll damage or destroy the appliance. If your device has no motor, then it’ll perform poorly, running on half the needed energy. If the device does have a motor, then the lower voltage can damage it.

Is 230V better than 110v?

For the same amount of energy 110V requires more current, hence thicker wires. 230V requires better isolation. In some rare situations 220V might be more dangerous to touch.

Can I plug 230V to 110v?

Can a 115v power supply be switched to 230V?

Now, switching to 230v while using a 115v line will normally not work because of the switching circuit. The circuit inside the PSU parallels the 115 into the PSU when set to operate on 115v, when set to operate at 230, it pushes the 230v straight into the PSU.

Why is there a switch on the back of a 115v box?

The 115v box has a little sticker in it probably meaning it was made for 115v current but for some reason there is still a switch on the back for the two voltages. Any ideas why they would do that?

Is it cheaper to make a 115v switch?

It’s cheaper to make a switch & some circuits inside the PSU than make a whole new one. Also, in different houses your computer room may only be 115V, as mine is. Some places it’s 230V, it depends on your house.

How does 115v and 230V work in a PSU?

The circuit inside the PSU parallels the 115 into the PSU when set to operate on 115v, when set to operate at 230, it pushes the 230v straight into the PSU. This happens before it goes into the circuitry that rectifies and cleans up the signal to produce a DC output.
