An online UPS system is also known as double conversion system. The transform the AC input voltage to stabilized DC which in then transformed to AC. On the basis of lower procuring and running costs but poor security, offline UPS are preferred over online UPS in small offices and data center. This approach overlook the differences between online UPS system like ability of few online UPS system to work in economic mode, which give finer power security at low cost.
A simple offline UPS system join the load to the input AC line. Line interactive system have potential to correct UPS output if AC input voltage vary beyond the set limits by means of an auto -transformer. These systems shift the UPS to battery operation in case utility voltage disrupt.
Because of uninterrupted connection to input AC power, line interactive system provide higher efficiency in comparison to an Online UPS. They may suffer from persistent transfers to battery operation in few cases in summer due to AC or in stormy winter seasons many power excursions may cause. Hence, exhibiting a critical load to failures due to battery failure or unsuccessful transfer will ultimately decrease battery life time.
A major difference between online UPS and interactive UPS is their working in Eco mode regime. An offline UPS works regularly from mains employing battery backup mode for small backup duration while online system can work in both the modes. An offline UPS will work in unsteady framework with recurrent transfers to battery. An online UPS if set to Eco mode will perform same work in same framework. Online UPS system with Eco mode provide on an average 5% power saving. This Eco mode feature doesn't have a price tag. It is implemented on the basis of software and because of this reason the price of online UPS will not increase. So it should be preferred over any type of other UPS.
