How long does a UPS power supply last? UPS power supplies are often used to power important equipment today. The backup time is the maximum time that the UPS can provide power to computers and other equipment after a utility power failure. Generally priced at about 500 yuan UPS power supply, connected to a desktop computer, you can supply power for about 10 minutes.
How long can a UPS power supply be used as a backup?

The UPS power supply can be used for a long time, has been the focus of attention of users, generally speaking, the UPS power supply is divided into two kinds, one is a very short time, that is, to provide a time to save information, and another, is for the power outage time is long, this kind of backup time is much longer.
Companies can choose according to a variety of models to suit their own supply time, there are various brands of UPS power supply long-lasting type for 1-8 hours. According to my usual type of work and demand, UPS power supply according to the standby time can be divided into normative and long-lasting type. The standard UPS standby is 5-15 minutes. Choose the UPS power supply that suits my own needs. If in the event of a power outage, only need to meet the requirements of the custody of data, exit, then you can choose the standard UPS If you equipment in the event of a power outage, a short period of standby time is still lacking to meet your needs, then you can choose a long-lasting UPS.
UPS uninterruptible power supply backup time is determined by the UPS energy storage device, the UPS is now generally sealed maintenance-free lead-acid battery as a storage device, the size of the battery capacity by the "number of hours (AH)" this indicator reflects the meaning of the specified current for the discharge time.
The same voltage of the battery, the number of hours of high capacity; the same number of hours of the battery, high voltage capacity, usually the voltage and the number of hours together to express the capacity of the battery, such as 12V/7AH, 12V/24AH, 12V/65AH, 12V/100AH. backup UPS built-in 7AH battery, its backup time is fixed; online UPS has a built-in 7AH battery There are standard models with built-in 7AH batteries and long-lasting models with external high-capacity batteries, so users can determine how much capacity they need depending on the backup time they need to achieve.
How long a UPS can supply power depends on the power of the UPS (which consumes itself), the power of the appliances it carries, and the capacity of the batteries it is equipped with. In principle, when the capacity remains the same, the smaller the power of the appliances, the longer the time; accordingly, when the power of the appliances is certain, the larger the battery capacity, the longer the time.
UPS can be powered for a long time, first, with the UPS capacity size, the larger the capacity, the longer the power supply time, and secondly, is connected to the UPS how much power-consuming equipment, the greater the power consumption, the shorter the time.
The main features of the backup UPS power supply
Power range: 300 ~ 2000VA
Working characteristics: the mains for a simple lift and filtering process directly to the load, when the input power does not meet the requirements of the battery power supply. In the vast majority of the time, the load uses the mains or after simple processing to the load power supply.
Advantages: low cost, few components, small size, high efficiency
Disadvantages: mains/battery power conversion time: 4~10ms
Low output accuracy, poor output waveform, square waveform output.
Main application objects: Power failure protection for single computer systems
The nominal standby time of the UPS is the maximum time the UPS can supply computers and other equipment after a utility power failure. Usually the UPS power conversion time can not be greater than 10ms (milliseconds).
