What is the UPS power supply?
UPS adaptation range is different, the change in output voltage of UPS + is 10-15% of normal computer voltage. When the power supply is abnormal or interrupted, the UPS immediately supplies the electric energy of the battery in the machine to the computer system through inversion transformation, in order to maintain the normal operation of the computer system and protect the computer's hardware and software from loss. UPS classification and characteristics, UPS power supply can be divided into two types of backup and online according to its working mode. According to its output waveform, it can be divided into two kinds of square wave output and sine wave output. Backup UPS power supply in the city power supply, the city power through the AC bypass channel, and then through the switch directly to the load power supply, the inverter in the machine is stopped. In essence, this UPS power is equivalent to a voltage regulator with very poor performance. In addition to improving the voltage fluctuation of the mains voltage, there is little improvement in the frequency instability of the mains voltage, the distortion of the waveform and the interference from the network.
Uninterrupted power supply, usually in order to prevent the sudden power failure caused by data loss, after the power supply, generally can maintain the computer power supply for about ten minutes,..
Is an emergency power supply, in fact, there are batteries, usually stored electricity, when the power failure, you can emergency power supply to the electrical appliances, to prevent sudden power losses.The average household can buy one at around 400, but only one computer for about 10 minutes. Belongs to emergency power supply.
The function and function of UPS, UPS is the abbreviation of Uninterruptible (PowerSystem), which is accompanied by the birth of computer. It is one of the common peripherals of computer. In fact, the UPS is a constant voltage constant current source with an energy storage device and an inverter as its main component. At the beginning of its development, UPS was considered as an alternate power supply
Backup power supply, when power, can provide power, small half can make the computer more than 5 minutes, you can save the files are in use, and safety; large, can be used for a longer time, but more expensive.
