What does a dual voltage power supply do?
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.

Answer +5, -5, +12, -12
Dual power supply is used to describe a computer system with twopower supply units (PSU's). This is to provide extra power for thecomputer's internal components.
Dual conversion uninterruptible power supplies operate by converting incoming utility AC power to DC and then convert the DC back to AC power connected to the load.
The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts. For more information see the Related Link shown below.
The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the… logic circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
Generally, there will be a 12+ volt rail, a 5+ volt rail and often a 3+ volt rail.
It's a power supply with a positive and negative voltage, where one of the voltages tracks the other. For example: the negative voltage tracks the positive. If you regulate th…e positive to 15v, the negative is going to be -15v. This allows very precise symmetric power.
Depends on the power supply, usually theres a red switch on the back that says the voltages that I can be. You can also change them by going to the boot setting(setting when t…he computer boots up)
-12, +12, -5, +5 & ground.
fu* ck of................
the power supply is tracked by two's.
Dual power supply means to have +ve and -ve supplies both. Like in Op Amps it is mentioned single or Dual supply.
the ATX standard supplies three positive rails: +3.3 V, +5 V, and +12 V
What should be the setting for a dual voltage selector switch on a power supply when using the computer in the us?
It can be used for anything with a nominal 12 v requirement. In cars everything runs on a nominal voltage of 12 v but is designed to run on 13.8 v which is the voltage whe…n the car is running.
What should be the setting for a dual voltage selector switch on a power supply when using a computer in the US?
The 110VAC to 125VAC range (not the 220VAC to 250VAC range).
