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.
Two technicians are discussing how to measure the voltage outputs of a power supply. Technician A says that the power supply must be connected to the system and turned on before voltage can be measu?
\nIt does have to be turned on. A highly regulated PS will be the same under load as without a load. But it may not be able to supply the amps. Best connect it and test it. WHO WON?
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)
Most often, power supplies for any type of equipment is givin to you when you buy what the power supply is for.
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)
As a general rule, there are several extra power connectors of varying types on the power supply. This allows for expansion with various drives and devices. Some power supplies don't provide the serial ATA (SATA) connector. In which case, you can use an adapter power cord to accommodate SATA hard… drives. (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.
Disconnect all the cord that come from the power supply and then unscrew it and pull it out.
in case of leading power factor the air gap flux inside the alternator will increase which may cause over heating of the stator end coil and overhang portions.
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)
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 t…hey are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car! (MORE)
Generally, there will be a 12+ volt rail, a 5+ volt rail and often a 3+ volt rail.
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.
The function of the power supply is to convert wall current to thecorrect current for the computer and distribute power to all theinternal computer components.
The same as any surge arrestor equipment - to prevent surges from damaging the (telecom) equipment.
+12 V, -12 V, +5 V, +3.3 V, and -5 V is included but is almost never used
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.

The two outside contacts (of four contacts) are connected to the power supply in the computer.
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
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.
It takes the mains supply and converts it to various lower voltages, suitable for the electronics in the computer. Usually 5v 12v 3v
1: It can cause the computer to not have power, at all, so that when you press power, absolutely nothing happens. 2: If it's surge protecting feature is down, it could let a surge through and damage components.
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.
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.

'Poor power factor' means that a load is drawing more load current is necessary for the amount of energy it consumes. The result is larger voltage drops along the supply lines and greater energy losses along those same lines. To overcome these problems, it would be necessary to install cables and ot…her equipment with larger cross-sectional areas -this is expensive, so it's much easier and cheaper to improve the load's power factor. To encourage consumers to do so, utility companies include a surcharge if the power factor falls below a certain value. All of this only applies to industrial/commercial loads, it does NOT apply to residential loads. Poor power factor has the following effects on the power supply: . High input current . over consumption of reactive energy . Increase in the cross sectional area of conductors (MORE)
This can very greatly from computer to computer. You will have to open the case of your computer to tell.
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.
In most common starting systems for gas (and, for that matter, diesel) powered vehicles, when the ignition switch is turned to the "start" position, several things happen. The combination ignition/start switch has multiple contacts: some allow electrical power to go to various accessories, some prov…ide power to the ignition system, and others allow power to flow to the starter system. The switch itself does no carry the high current necessary to power the starter motor. Instead, it typically will allow power to flow to a "starter relay", which is a kind of electrical switch. The electricity from the switch energizes a relatively small electromagnet which is used to operate a much larger set of contacts. These larger contacts then carry the high power used to operate the starter motor itself. Of course, newer cars are somewhat more complex. In most newer cars, the start logic is controlled by the cars' computer, and the ignition switch is simply used to tell the computer that someone wants to start the engine. The computer looks at several different things, including the cars' security system (is the correct key or electronic fob being used?), but once it's satisfied, it then sends power to a starter relay, which then allows power to flow to the starter motor. (By the way, the various hybrid models are even more different, and should not be included in this description!) (MORE)
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.
The power supply is always batteries. Many series and differentvoltages. The popular voltage is like imalent flashlight in2.8V--9V.
It can be used for anything with a nominal 12 v requirement. Incars everything runs on a nominal voltage of 12 v but is designedto run on 13.8 v which is the voltage when the car is running.
