An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. Offline UPS Offline UPS connects the computer to the ESKOM's power grid (or to a generator) until the voltage falls below a certain level, in which case, the UPS switches over to battery backup. The switch-over time can be as long as 25 milliseconds depending on the amount of time it takes the standby UPS to detect the lost utility voltage. The UPS will be designed to power certain equipment, such as a personal computer, without any objectionable dip or brownout to that device. Online UPS Online UPS connects the computer directly to the battery backup at all times. This type of UPS is able to tolerate continuous under-voltage brownouts and over-voltage surges without consuming the limited reserve battery power. It instead compensates by automatically selecting different power taps on the auto-transformer. Other UPS features may include:
What is the difference between VA and WattsUPS are rated in VA (Volt-Amps). This is a basic rating for UPS and is the Voltage multiplied by the Amperage the UPS handles. At 220Volts, a UPS that can supply 1Amp would be rated 220VA. This however is not the real power for AC devices because AC power rating requires the power factor to be taken into account. A 1000VA UPS would therefore have an AC power rating of approximately 600Watts. What is power factor? In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. Typical power factors | |||||
