  Uninterruptible Power Supply (UPS) FAQ
A: An Uninterruptible Power Supply is a device that sits between a power supply (e.g.
Another school holds that since almost all computers use switching-type power supplies, which only draw power at or near the peaks of the waveforms, the shape of the input power waveform is not important.
A typical PF (power factor: Watts/VA) for some computers may be as low as 0.6, which means that if you record a drain of 100 Watts, you need a power source with a VA rating of 167.

 UPS ( Uninterruptible Power Supplies, Uninterruptible Power Supply, and Uninterruptable Power Supply) Definition
DEFINITION: An uninterruptible power supply (UPS) is a device that allows your computer to keep running for at least a short time when the primary power source is lost.
All of the majors options related to power and cooling are covered, including what is state of the art, how best to exploit it, and what to look for in the future.
If you are using the computer when the UPS notifies you of the power loss, you have time to save any data you are working on and exit gracefully before the secondary power source (the battery) runs out.

 The DIY (or, if you must, "Ghetto") UPS
That power supply's connected to the mains on one side and to the battery and an inverter (the box on the right), in parallel, on the other.
Your ordinary "seven amp-hour" 12 volt SLA brick may or may not be able to deliver as much power as you'd expect from that rating, even in the lower-current two-battery 24 volt configuration that a lot of UPSes use.
If you connect a lead acid battery to a power supply that's set to deliver the same voltage as the battery can hold when it's fully charged, you'll charge the battery, and you won't overcharge it.

 Uninterruptible power supply (UPS)
Standby or off-line UPS allows house power to flow to electronic loads until it detects a change in voltage or a power outage, then switches the load from the incoming line to internal batteries.
Powers the computer or other equipment from an internal power supply 100% of the time.
AC power from the incoming line is converted to DC, converted back to AC and then fed to the computer.

 ITworld.com - Uninterruptible power supply
Like the standby power supply, the line-interactive UPS can be inexpensive and efficient because it supports the entire critical load only during power disturbances.
The delta converter connects in series between the power source and the load and compensates for any difference between the required output voltage and the electric utility's supply.
A power factor of 1.0 indicates the current is in phase with the voltage and reactive power is zero.
