In 480 volt 3-phase power supplies, each single phase lead has a voltage of 277 volts from lead to ground. There are 277 * square root of 3 (1.73) = 480 volts phase to p…hase.
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.
+5V, -5 V, +12 V, and -12V Source: http://www.studydroid.com/index.php?page=viewPack&packId=85684
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!
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or …'phase voltage', is 120 V.
The line-to-neutral (not 'phase-to-neutral'!) voltage on a 400V 3-Phase wye-connected system is 230V. Line voltage is the voltage as measured between any two (2)… line conductors (hence its name!). Line voltage is often referred to as the 'line-to-line voltage'. Phase voltage is the voltage as measured between any single line and neutral. Phase voltage is often referred to as a 'line-to-neutral' voltage. "400V" on a 400V 3-Phase wye-connected power supply indicates its line voltage. Line voltage in a wye system is always the phase voltage multiplied by the square-root of "3" (1.732) and reflects the vector sum of two individual phase voltages present in a three phase system. Thusly, if the line voltage is "400V", then the phase voltage is 400V divided by the square-root of "3" (1.732), which is 230V. Examples of this for North American power systems are 120/208V, 277/480V and 347/600V. Examples for other areas of the world are 220/380V, 230/400V and 240/415V.
by d way input only
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.
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
Input would be 120v at 60hz. Standard US wall power.
Output is: DC10V - 800mA - Center Positive
the ATX standard supplies three positive rails: +3.3 V, +5 V, and +12 V
The electric voltage are energy to my system.
This can very greatly from computer to computer. You will have to open the case of your computer to tell.
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.
