First, what is UPS? Its working principle and application range have that? The

An uninterruptible power supply (UPS) is a power-assurance device that allows its loaded equipment to be protected from external power system interruptions for a period of time.

With the continuous development of digital computer technology, the scope of its application has gradually deepened into the industrial control, banking, power, military, finance, communications and other important sectors, which also put more stringent requirements on the stability and reliability of the computer. The emergence of UPS is to deal with the sudden power outages, voltage instability, power line clutter* and other issues that often occur in the power system to ensure that the computer system can continue normal work in the event of a power supply problem.

UPS works like a reservoir. When the external power supply is normal, in addition to the normal supply of power to the load, the UPS also converts a portion of the electrical energy into chemical energy. Once the external power suddenly interrupts supply, the UPS will immediately start the inverter device, rapidly converting chemical energy into Power continues to supply power to the load to ensure proper operation of the load device.

Second, how to choose a suitable UPS power supply for you

According to statistics of the world’s most professional UPS power data website, the 86ups.com website, there are currently as many as 20 common UPS power brands in the market, and a total of 1,643 models of UPS power products. . Faced with so many various types of UPS power products, which one is more suitable for you?

1, online and backup UPS power supply how to choose

The on-line UPS has a higher price, but its protection function is very perfect. It can filter out most viruses parasitized on most power grids and fully guarantee the stability and safety of the load devices. Backup UPSs are small in size and low in price, but not for some. Particularly important equipment systems can also prevent data loss caused by power outages. 

If economic conditions permit, of course online UPS first. From an economic point of view, however, a standby UPS power supply is sufficient for the average family or a less demanding office.

2, choose a large capacity of UPS power enough

At present, the average power consumption of a computer is about 250 VA, and a standby 500 VA UPS can provide approximately 10 minutes of power for it. This time has completely guaranteed that you have enough time to save the file and then shut down the computer normally. There are multiple computers at home that can calculate the total power of their own, and then select the appropriate UPS capacity. For some special commercial and industrial applications, the calculation is more complicated. Because these departments require UPS, it is often necessary to ensure that dozens of computers can work continuously for more than 10 hours or even tens of hours in the event of a power outage in the power grid.
