What dose Uninterrutable Power Supply(UPS) use for?
The Uninterrutable Power Supply(UPS) is really a backup power for computer or other electronic system in case of power failures occur, or line failures. In case of sudden power failures, computer still working by raising resources from the stored electricity to help users store the data and stopped the system without loss of data or be a temporary break.
What is UPS using for normal computer?
: It depends on the power consumed by computers. If you use the computer normally with only 1 CPU, 1 monitor, you should use the type of off-line UPS with power of 400-500VA.
How necessary is UPS in the electrical system?
The Uninterrutable Power Supply(UPS) is an important part of system resources overall. In case of power cut, the generators running are not fast enough to keep the operation of computers. The only UPS to satisfy this case. For large buildings, generators boot just as soon as power grid off. But also to take a few minutes(4 minutes), the generator is stable. During that times the building without electricity (there are some problem happens during this time ???). If use of UPS plus to the system will completely overcome this (supply during power grid temporarily).
What is different between tow types of 'On-line' and 'Off-line'?
There are tow basic type of UPS. They are 'On-line' and 'Off-line'. The 'Off-line' is taken directly to the electric grid to the first output socket and charging power to the battery storage if power grid stability. It regularly monitor electricity grid for input voltage changes exceed the threshold allowed or not, if they have identified as problems. At that time, the AC-DC inverter will work to provide power from the battery for load stability in a time called backup time. Period to convert from power grid to electricity of battery be temporary loss of resources, typically about 5 ms. Around this time it is not affected for most types of load. + The 'On-line' UPS: It was designed with DC-AC converter. It provides sources to equipment directly, no time to convert (5ms) between inverter and electricity as offline. In this type of design, all input sources is always converted into DC power, just give a part of changing to battery, just give a part of loading to inverter operation. DC-AC converster is responsible for providing AC power for permanent using load. When the power grid cut, battery keeps input DC for the converter to continue to work. Therefore, the output power of converter will be continue to the load without interruption at all. The converter part has a task of fixed (constant-duty) so the price quite expensive. In a number of reliable devices to save electricity, there always be Bypass mode. It means that when the inverter is damaged it will try to connect directly load to the electrical grid.
What is the surge power?
Surge power is the sudden skyrocketing of electricity exceed compared with usual activities. The increase may overburden active devices.
What is UPS using for normal computer?
It depends on the power consumed by computers. If you use the computer normally with only 1 CPU, 1 monitor, you should use the type of off-line UPS with power of 400-500VA.
