Answer If it is a computer power supply it is the box that gives the computer its power from the outlet.
A power supply gives electrical power to all the components and parts of the computer. The power supply consists on several wires that connect to specific parts of the computer. Examples are the IDE/SATA CD/DVD Drive, IDE/SATA Hard Disk Drive, the motherboard, etc. Power supplies are only a computer… part in a desktop computer, NOT a laptop computer. (MORE)
What are the 5 voltages produced by and BTX power supply?. +12v -12v +5v -5v +3.3v
...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, fo…r 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. (MORE)
+12 volt , -12 volt, + 5 volt, - 5 volt, and + 3.3 volt.
A power supply does not create power or energy. This would be in violation of the Law of Conservation of Energy. Rather, a power supply changes the form of an available source of power or electrical energy into a form that is acceptable for use by electrical or electronic equipment. The input …form is electrical energy defined by voltage or current or power, with a given impedance level, and frequency. The output form from the power supply is a different voltage or current or power, with a different impedance level, and possible a different frequency. Another possible is for the input and output to be of the same form but electrically isolated from each other for safety and performance concerns. (MORE)
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 phase.
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.
Power supplies are typically thought of as electronic or electrical equipment which changes the form of a source of power into a form which is acceptable for use by equipment that performs a useful function. For example, in the typical home, power is available at electrical wall outlets in the fo…rm of 120 volts, 60 Hz alternating current (in the United States). This means that electrical current with RMS amplitude of 120V is constantly reversing in direction 60 times per second. This is the way the electrical power is generated by rotating machinery at the utility company. But this form of power is not directly useful for electronic equipment which typically requires a constant voltage level of some amount, perhaps 12 volts direct current. The role of the power supply, in this case, is to change the form of the power from the alternating voltage to a constant voltage at 12 volts. (MORE)
In the U.S.A., 110VAC is the usual household receptacle voltage where lamps, TV's etc are connected and the computer, printer & related devices are also connected. Other countries may have different operating voltages required for computers.
Everything in your computer requires power. The power supply has leads running to the motherboard to support CPUs, PCI slots and their respective devices, USB ports and optical drives. #2 --- A power supply does not really supply power in the sense of a reservoir, it is actually a power conver…ter. Light bulbs and heaters use the power coming out of your wall, but there is no electronic gadget that uses power directly from the wall. The 110 volts AC (alternating polarity) power must be converted to voltage levels that the circuits are designed for, and usually at low voltage 5 or 12 volts DC (steady direct polarity). There is a huge industry that builds power supplies that do this. (MORE)
For three-phase, three-wire, systems, single phase is obtained by connecting the load between any two of the three line conductors (not 'phase conductors'!). For three-phase, four-wire, systems, single phase is obtained by connecting the load between any two of the three line conductors, or betwe…en any one of the line conductors and the neutral conductor -depending on which connection gives you the appropriate voltage. Before you do any work yourself, on electrical circuits, equipment or appliances, always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. (MORE)
A single phase power supply has two "hot" legs or conductors which have a sine wave that are 180 degrees apart.. A three phase power supply has three "hot" conductors which have a sine wave that are 120 degrees apart..

From line-to-line (any two of the three leads) voltage or ' linevoltage ', the voltage is 208 V. The line-to-neutral (one of thethree leads and the neutral conductor), or ' phase voltage ',is 120 V.
Generally, there will be a 12+ volt rail, a 5+ volt rail and often a 3+ volt rail.
What voltage supplied by Florida Power and Light would be the least expensive to run a 3 phase 750 KW motor?
Motors are rated in horsepower, not KW. A 750,000 watt motor, at 220 volt, would be a 1005 H.P. motor and about the size of a large pickup truck! I suspect you're asking about a 750 KW generator. You must not only supply the correct voltage and amperage to operate it, you must have a 3 phase power s…upply. Unless you're in a commercial bldg. you likely don't have 3 phase power and can't operate that generator. (MORE)
The line-to-neutral (not 'phase-to-neutral'!) voltage on a 400V3-Phase wye-connected system is 230V. Line voltage is the voltage as measured between any two(2) line conductors (hence its name!). Line voltage isoften referred to as the 'line-to-line voltage'. Phase voltage is the voltage as mea…sured between any single lineand neutral. Phase voltage is often referred to as a'line-to-neutral' voltage. "400V" on a 400V 3-Phase wye-connected power supply indicates itsline voltage. Line voltage in a wye system is always the phasevoltage multiplied by the square-root of "3" (1.732) and reflectsthe vector sum of two individual phase voltages present in a threephase system. Thusly, if the line voltage is "400V", then the phase voltage is400V 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 are220/380V, 230/400V and 240/415V. (MORE)
At Least, 115 volts. Which is standard from a wall outlet. If should not matter how many volts your computer needs, but the watts does. For most computers they need anywhere from 100-800 watts.
I think the cause of ripple voltage would be from a bad ground or capacitve voltage.
The maximum supply voltage per the data sheet is 5.25 volts. This is a common max for TTL type IC's.
Your power supply unit, PSU. Takes AC power and distributes so much power to each connector. Each PSU, depending on the wattage of the unit gives each connector so much voltage. Each connector is designed for a certain piece of hardware that requires different voltage.
+12 V, -12 V, +5 V, +3.3 V, and -5 V is included but is almost never used
The term, 'nominal', simply means 'named'. For example, the nominal supply voltage for a residence in the UK is 230 V . But this doesn't mean that the actual supply voltage is 230 V, because the supply voltage is allowed to vary by -6% and +10% of the nominal voltage. In other words, the actual… voltage could be anywhere within the range of 216.2 V to 253 V. In fact, during periods of heavy load, the actual voltage would tend towards the lower end of this range, whereas during periods of higher load, the actual voltage would vary towards the upper end.

The circuit designer typically picks a family of devices to implement the functionality of the circuit. The devices will fall into a range of voltages. Many integrated circuits operate at 5VDC, so it is an obvious choice for many applications.
AC power, 120v 60Hz in the USA. Can be measured at the wall outlet with a DMM set on AC volts. usually, the power supply output is DC. Example: A 5 Volt DC power supply, the 120V AC from the wall outlet goes to a step down transformer (in the DC power supply) then, the stepped down 5Volt AC power go…es through a Rectifier which, converts the AC to DC. The DC has ripples at this point. then, next stage there are Capacitors which are storage devices. they provide smooth DC power. next stage, regulation.. (MORE)
Capacitors are not working properly due to which ripple voltages are not eliminated and causing fluctuation.
It depends on the application, and on the implementation of the UPS. Some UPS devices function as an AVR by boosting the output voltage when the input voltage sags. A UPS will also help you during a complete power outage, which an AVR will not. A UPS however has batteries which need to be periodical…ly replaced. An AVR does not, which means less maintenance.

What are five voltages that can be produced by an ATX or BTX power supply Which voltage is seldom used?
The voltages are +12,-12, +5, -5 and 3.3. There's also ground or 0. -12 is seldom used.
A: Ripple is a residual voltage evident as voltage following the AC input frequency. The ripple magnitude is a function of not enough of both filtering capacitance or overloading the output. Increasing capacitance will reduce the ripple or reducing the loading
A: It doesn't have to be a transformer it could be direct from the AC Line what a transformer does besides lowering or raising the voltage as required it also provide safety of isolation from the AC source
A: Depends on the circuitry involved an op amp normally has a 90 Db rejection from variation, Logic gates however are more sensitive to power supply variation for the simple point that triggering points changes which translate in false triggering and the circuits miss behaving
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)
Lowering voltage will lower power consumption, but there will come a point where the desired operation of the device will not be met. For example if you had a variable voltage like a dimmer on a light bulb, you can reduce the voltage to a point where the bulb no longer emits a useful amount of ligh…t. (MORE)
Depending on the power supply, +12, -12, +5, - 5 and ground. Some also use 3.3.
The circuit by itself doesn't determine the voltage of the powersupply. If there's some additional requirement that goes along with thecircuit, such as "The current through the circuit must be XYZ amperes.", or "Thevoltage across the third component from the north end of the circuit shall be ABCvol…ts,", then that requirement would dictate the power supply voltage. But inorder to calculate it, you'd need the knowledge of every component in the seriescircuit. (MORE)
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
You need to assess the frequency, amplitude and see if there is any distortion in the waveform. The best way is with an Oscilloscope.
In theory, voltage should be the same around the clock. In practice you may get a tad higher voltage at nights, as there's less load on the system. With most people asleep, there aren't as many machines running.
'Conversion' is unnecessary. A single-phase supply can be obtained simply by connecting the load across any two line conductors, or between a line conductor and a neutral conductor. The voltage rating of the load, of course, must match the voltage obtained from the supply.
In parallel circuit there is no change of ratting voltage but there is also change of current because in parallel circuit in every node of the apply circuit there is no change of voltage but the current distributed through the node as per as required and it reduces the current reading of the main cu…rrent source.

This can very greatly from computer to computer. You will have to open the case of your computer to tell.
Most buildings with a 3 phase service feed are 277/480v. That's 277 phase to ground and 480 phase to phase. This is then transformed to 120/208v. Answer for European Systems In Europe, the nominal low-voltage three-phase distribution systems are 400 V line-to-line (i.e. line voltages) and … 230 V line-to-neutral (i.e. phase voltages). (MORE)
Obviously, you don't want the voltage to sag. For computer power supplies, you want the power to be even, pure, and clean without any ripple.
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.
There are many guides on the internet for building a high voltage power supply. The average cost for building one of these power supplies is around $20.
High voltage power supplies have many uses. It is most commonly used to supply power from a device to the circuit. These are great for people who need to supply their house with power.
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.
