An uninterruptible power supply, UPS, also known as UPS (uninterruptible power supply English), is a device that, thanks to batteries or other energy storage elements, can provide power for a limited time and for a blackout all the devices connected. Other features that can be added to these teams is to improve the power qualityéctrica reaching loads, ups and downs filtering and eliminating voltage harmonics of the network in the case of using AC. There are different types of UPS UPS DC loads connected to the UPS require DC power, so they will transform the alternating current to direct current sales network and use it to power the load and store it in your batterys. So they do not require converters between the batteries and loads. UPS AC UPS obtained These outputs an AC signal, so they need an inverter to convert the direct signal from the batteries in an alternating signal. UPS standby (Standby Power Systems) This system has two main circuits: the power line, which only addsa stabilized and additional filtering of each team to normal feed, and the actual circuit UPS circuit whose core is called "inverter". It is called system "standby" or waiting, because the circuit of alternative power, the inverter is "offline" or inactive, waiting to become operational when it produces a failure in the power supply. It has a switching element that connectsand either circuit switched alternately. UPS line-interactive (in-line) This type of UPS regulates voltage variations by elevations or reductions in mains voltage. During these interventions, the UPS uses its battery to perform the voltage regulation. UPS online (online) In contrast, the UPS "online" (on-line), the battery and the inverter are permanently It is utiized, ensuring a maximum response in a timely manner before the event of network failure. In addition, they can also correct the frequency shifts as re-generate the ac wave permanently. Diagram UPS online In the picture (1) Rectifier The picture (2): battery in the picture (3): Inverter

IEC connector is the common name for a set of thirteen power connectors (called the connector specifications) and thirteen outlet panels (called input) specification defined by IEC 60320 (formerly IEC 320) of the International Electrotechnical Commission ( IEC). When used without other qualifiers, "IEC connector" usually refers specifically to the C13 and C14 connectors.

In IEC connector or cable with a base (usually plastic) and a plug to connect to the socket (plug), if we put these two things we would get the named SCHUKO is the overall connector. The schuko not determine the type of connector. It would be determined by the specification of the International Electrotechnical Commision (IEC). We leave a small sample of Schukos internationally.
