Due to the unstable power supply quality hp g61-100ea laptop keyboard
, often causing computer equipment hardware damages, loss of valuable data, so the UPS has gradually become buy computer equipment indispensable standard equipped with. However, how to choose and buy UPS became troubled users often one of the most important problems. Therefore, the author in the sales process, customers often put forward questions to arrange, and puts forward solutions, and I hope it can help the reader UPS of choose and buy.
A, what is meant by UPS?
This is usually the first contact UPS customers the most often asked a question. UPS English name is Uninterruptable Power System, referred to as UPS. The so-called UPS, just as its name implies, it is when there is a power failure can take a continuing supply mains power equipment, like emergency lighting equipment, but UPS capacity bigger and faster response, the use of more wide, set when the mains sudden interruption, UPS can be used for emergency replace mains, and because of limited capacity, the hp g61-100sa laptop keyboard
general are applied to protect the important equipment, such as computer equipment, fire equipment, medical instrument, etc. Of course UPS also has its use restrictions, and especially the inductive load, like electric fan, air conditioners and home appliances are not applicable, because the inductive load will produce anti electric meter more precision.
Second, UPS used in where?
Electromotive force. In addition the start current is larger equipment is not applicable, because it too much starting current will cause UPS misoperation.
Third, why to use UPS?
With our computer as an example to illustrate this problem. Today, if there is no use UPS, so when the mains happens unusual, will cause the computer is down machine, even cause hardware fault, when upkeep will not underestimate; hp g61-101tu laptop keyboard
Hardware failure can spend maintenance, but the information stored in hard drive? That's rich also can't buy. Therefore, for your equipment buy UPS, like to buy insurance, encounter. Here attached explanation is necessary, UPS is not only when there is a power failure to play a role, when appear mains abnormalities, such as mains voltage is too low, too high, surge, spike, line noise is enough to affect equipment normal operation of power supply quality, UPS will play a role. Therefore, the importance of UPS is obviously.
Four, UPS is how to work?
UPS power supply when the mains principle is normal, the machine will mains of the alternating current (ac) to direct current, and then to the battery for electric power disruptions use; Once when the mains when an exception occurs, then will be stored in the cell of the dc conversion for alternating current (ac), supply load continue to use hp g61-102tu laptop keyboard
, achieve uninterruptable power function. Here we emphasize that UPS and not when the power will be action, such as the voltage is too low or too high, instantaneous surge enough to affect the normal operation of equipment, UPS all can action, to equipment to provide stable and clean powerhttp://batteryonline.blogdetik.com/2012/09/11/what-is-uefi/ http://startbattery.weebly.com/1/post/2012/09/what-is-uefi.html
