Typical home use UPS devices for computers are plugged into your AC power. There is an input circuit that converts AC to DC and continuously charges the internal batteries in the UPS device. The DC output from the batteries is then converted to AC to power the computer or other device connected to the UPS. There is also a circuit that detects that the house power is no longer functioning and typically sounds an alarm of some sort.

∙ 11y agoAn uninterruptible power supply (or UPS) operates, in most cases, as a specialized battery for the computer. The computer will be plugged into the UPS battery. And when the power goes down or surges, the UPS will take over and supply power at the proper voltage.

What is the Working principle of instant power supply?
IPS is instant power supply that is a backup system that start when main energy not available.
Working principle of unintrupted power supply?
current from storage batteries
All injectors operating together?
Injectors that have a resistor in the power supply are called
The power-good signal from the power supply prevents the computer from?
The power supply's power-good signal prevents a computer from operating on improper voltages and potentially getting damaged. Typically, a computer will only start up after receiving the power-good signal.
A government operating on the principle that governmental power must be limited and that governmenT officials should be restrained in their exercise of power over individiduals is called?
It is called the "Supreme Court"
Replaced power supply and computer is now running louder why is that?
The power supply that you replaced the old one with might have a louder, faster fan inside. Also, your last power supply could have broke down due to it's fan being shot and it wasn't operating at all.
What must you match when purchasing a power supply?
The equipments power requirements, and the mains voltage. The output of the power supply must be able to deliver the correct voltage to the equipment, at the appropriate wattage. Additionally, it should be capable of operating on the supplied mains voltage and wattage.
Operation principle of three phase power supply?
http://en.wikipedia.org/wiki/Three-phase_electric_power Click on this link from Wikipedia. It gives an excellent description of three phase power.
Which uses less power a 9v CD player operating off of a WAGAN 12 v power supply inverter or a 9v CD player operating off a 12-volt-to-9-volt converter plugged to the WAGAN 12v power supply?
Ideally both ways use the same amount of energy. But it is not desirable to operate a 9V CD player at 12V
Why would a computer power down after it has been operating for a few minutes or a few hours?
Overheating. Is it overclocked, is there dust in the power supply, is there no air flow. Very common in laptops.
What is surge impedence?
Usually associated with switching power supply when dormant to active the input impedance can change dramatically until-operating normally
Why dc components operate at low voltage compared to ac component?
Because equipment operating on DC is usually low-power electronic equipment, and it uses a power-supply to convert the house AC supply to DC at the right voltage. Most appliances needing high power are designed to run on AC because that is the normal supply to houses.
