The voltages supported by a UPS power supply in the US ranges from 50Hz, 60Hg or 400Hg frequency conversions. This may not be an exact answer to the question.
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
Maintain constant stable supply and reference voltages.
The power supply in a computer runs the 110 volts mains power through a transformer into a lower voltage, then lowers that into different voltages (+5v, -12v, +12v, +3.3v) which i believe are then stabilised independently. The power supply also handles the turning on/off the voltages triggered by a signal from the motherboard.
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 the computer boots up)
+5, -5, +12, -12
To give steady voltages at the levels the equipment requires.
The Power Supply
A faulty power supply does not supply any power at all to a computer or supplies incorrect voltages. Most of the time faulty power supplies are not serviceable and require replacement.
A computer's power supply unit provides all needed voltages for the components of a computer that are internal. Externals either draw power from the USB bus (which in turn gets it's power from the aforementioned PSU or a Hub with a power supply) OR have their own internal power supply with a cable.
...It "supplies the power" to whatever device you're referring to.Baffling, I know.Another answer:A power supply converts 120V or 240V AC power (sometimes called "wall", "line" or "mains" power) into various regulated DC voltages needed in a piece of electronic equipment. In a computer, for example, the power supply will typically provide +12V, +5V, +3.3V and -12V sources to the various components. Voltage regulators in the power supply help keep the voltages steady, even when the input voltage sags.
