What's the difference between online UPS and pure online UPS?
UPS is the abbreviation of uninterruptible power system, which is an important external equipment to provide continuous, stable and uninterrupted power supply.In principle, the UPS is a power electronics device incorporating digital and analog circuits, automatic control inverters, and maintenance free storage devices;Functionally, UPS can effectively purify the city power when the city power is abnormal. It can also supply power to the computer and other equipment for a certain period of time when the city power breaks suddenly, so that you can have enough time to cope with it;From the use, with the coming of information society, UPS is widely used in the information collection, transmission, processing, storage and application to each link, its importance is increased with the increasing importance of information applications.- - - - - - - - - - - - what kinds of 2.UPS?
This UPS uninterruptible power supply has the inverter in working state, it first through the external circuit AC into DC through high quality inverter to convert DC to high quality sine wave AC output to the computer. The main function of the online UPS in the power supply condition is to regulate voltage and prevent the interference of the electric wave. At the same time, the management of the battery is managed. In the case of power failure, the standby DC power supply (battery) is used to supply the inverter. Because the inverter is working all the time, there is no switching time problem. It is suitable for occasions where the power supply is strictly required.
On line UPS means that no matter whether the network voltage is normal, the AC voltage used by the load will go through the inverter circuit, and the inverter has been in the working state. Therefore, when the power failure occurs, the UPS can immediately convert the stored power into the AC through the inverter to supply power to the load, thus achieving the switching target of zero output voltage interruption.
