Line Interactive UPS

Line interactive UPS is used for small business, web and departmental servers. When there is a power shortage or the main input power fails, the transfer switch opens and the power is connected to the UPS output from the battery, thus making sure you have uninterruptable power till your battery lasts. This type of design provides additional filtering and harvests economized switching transients in comparison with the standby UPS technology.
This device also adds voltage regulation when the input voltage varies by adjusting the transformer taps. Keeping voltage regulation as an important feature specially when low voltage conditions exist, the UPS transfers to battery till the current is stabilized.
