How to choose UPS power
Wednesday, October 7th, 2009How to choose UPS power
UPS
First, UPS and function
Whether you have had that kind of experience. The arduous work done is irrevocably lost because of losing electrical power suddenly on the computer, the reason is only forgotten or not found time to save, that kind of feeling really makes people annoyed and depressed very much. Then, is there method of preventing the occurrence of this kind of situation? Have! That is UPS!
The Chinese meaning of UPS is “ The incessant power “ ,It is English ” Uninterruptable Power Supply ” Abbreviation,it can ensure there aren’t computer system, prevent the data from being lost.
Second, operation method of UPS
Operation method of UPS such: Connect the computer system and outside apparatus to on UPS, link UPS with city electricity, when the electricity cuts off in the city, UPS give out, report an emergency and ask for help or increased vigilance, users should save rapidly at this moment.
Third, UPS classifies and operation principle
UPS divide as from line type (off line) according to working way their Type, online (on line) Interdynamic formula (Line-interactive) on the line of sum Three kinds. Now we say something about the operation principle of three kinds of ups separately:
1,Leave line type UPS
In the battery to charge the state at ordinary times from line type UPS, go against the becoming device while losing electrical power and switch over to the working state promptly, change steady alternating current into export direct current that battery offer, so UPS known as reserve type UPS from line type. But the UPS have one switch over time problem, so unsuitable to use in key power supply place of can break downing. But this switches over time very short in fact, generally lie between 2 to 10 milliseconds, and the computer’s own exchange type power supplying device can keep about 10 milliseconds while cutting out, so the personal computer system will seldom go wrong because this switch over time.
2,Online UPS
Online UPS has been making it go against becoming device in working state all the time, it changes the alternating current of outside into the direct current through the circuit at first, and then change the direct current into the sinusoidal wave alternating current of high quality to export to the computer through the going against the becoming device of high quality. Online UPS main function under the state of supplying power is the steady voltage and prevents the electric wave from interfering with; Use spare direct current source while losing electrical power ‘ Battery group) Give and go against the becoming device and supply power. Because go against the becoming device and work, does not exist and switch over the time problem, suitable for the occasion required strictly to power.
3,Interdynamic UPS on the line
This is a kind of intelligent UPS, whether can detect and examine the outside to input the voltage within the normal range automatically, if there are deviations that can be stepped up or stepped down by the circuit of steady voltage, offer more steady sinusoidal wave output voltage. And it and computer can pass the interface of the data ‘ Such as one bunch of mouths of RS-232) Carrying on the communication of the data, through controlling the software, users can control the power and UPS state from computer screen directly, simplify, facilitate the management, and can improve the dependability of the computer system.
Fourth, developing direction of UPS
1,Intelligent, networked
The control method of the total word, carry on the control of programming to the machine parameter through CPU within UPS;
A UPS can join many computer systems at the same time;
Interface of usable communication and computer communication, cooperate with intelligent to control software and procotol use households of convenience, a high-efficient one in here even long-range analysis and manage whole computer and UPS system.
2,High dependability and security
Detect and examine automatically: UPS starts the component promptly while starting the machine ‘ Go against becoming device, battery,etc.) The inspection of load, easy to discover the problems in time, avoid producing any careless mistake;
Self-protection: Design through the self-protection, no matter UPS overloads, shorts out, the battery is too low in voltage or UPS temperature is too high, UPS will all shut down automatically;
Direct current starts the machine: Give full play to the urgent spare function of UPS;
Extremely strong overload capacity: Can still work for longer time even in case of great overload;
Double machine hot spare functions: Offer the double power protection for land network of the office, even a UPS breaks down, will not lead to the fact either the network cuts off.
Fifth, exertion of UPS
If your computer just plays games and surfs the Net to see VCD at home, then perhaps you would not need UPS at all, because all these are not any very important thing, unless you are a fanatic game player who can’t tolerate the game with lost datum, you can choose one a ordinary one from line type UPS then; But if you are a writer or a designer, the work done is very important, you must choose one a high-quality one from line UPS, work achievement to so as to ensure you forfeit because of losing electrical power then; And if is enterprises required strictly to security of the data such as the bank, civil aviation,etc., allocate the intelligent networked intensity extremely high and online soon or interdynamic UPS on the line.
