UPS uninterruptible power supply (UninterruptiblePowerSystem) English name abbreviations, it is accompanied by the birth of the computer and appear, is one of the commonly used computer peripherals.

Functions and functions of the UPS:

 

In fact, UPS is an uninterruptible power supply with constant voltage and constant amount containing energy storage device and inverter as the main component. In the early days of its development, UPS was considered only a backup power source. Later, the surge voltage, peak voltage, voltage transients, voltage drop, sustained over voltage or under voltage and voltage interruption of power quality problems, to distract equipment, such as computers, electronic systems, damaged sensor, information loss, such as disk program wiped out severe consequences, cause huge economic losses. Therefore, UPS has been paid more and more attention, and gradually developed into a power protection system with voltage stabilization, frequency stabilization, filtering, electromagnetic and radio frequency interference resistance, voltage surge protection and other functions.

 

A wide variety of devices are currently available on the market, with output power ranging from 500VA to 3000kVA. When the mains is supplied to the UPS, the UPS regulates the mains voltage (220V±5%) and supplies power to the computer. At this time, the UPS is an AC mains voltage regulator, and it also charges the battery in the machine. Due to the different UPS design, UPS adapt to the range is also different, UPS output voltage in ±10-15% change is generally normal computer use voltage. When the mains is abnormal or interrupted, the UPS immediately converts the electric energy of the battery in the machine to the computer system by inverter to maintain the normal operation of the computer system and protect the software and hardware of the computer from loss.
