Fundamentals of Uninterruptible Power Supply: The uninterruptible power supply‚ commonly known as UPS or the battery backup is something that is used at several places for emergency situations. An UPS is something that stores power inside it and provides power as and when required to the electric devices. It is used with several electric devices‚ such as computers‚ data centers‚ home power systems etc. The main reason why people use UPS is to provide short term supply of power to different devices

The term is most commonly applied to electric power converters that convert one form of electrical energy to another‚ though it may also refer to devices that convert another form of energy (mechanical‚ chemical‚ solar) to electrical energy. A regulated power supply is

Power Supply Regulation DC-DC voltage converters are often used to provide a regulated voltage supply from an unregulated voltage source. Unregulated voltage sources can be rectified line voltages that exhibit fluctuations due to changes in magnitude. Regulated voltage supplies provide an average DC output voltage at a desired level (3.3 V‚ 2.5 V‚ etc.)‚ despite fluctuating input voltage sources and variable output loads. Factors to consider when deciding on a regulated voltage supply solution include:

It’s entirely possible that a cord could just slip out from the outlet while you’re working. If power is present to the monitor and other peripherals‚ yet there is no power to your computer‚ there is likely something wrong with your power supply. 2Hit the power button. The most obvious clue is that the system will do absolutely nothing when you hit the power button. If there is
