The battery is activated when even lower voltages are recorded. Online UPS units constantly supply power to connected equipment from an internal battery, with battery recharging occurring on an ongoing basis. There is no lag time when power failures occur since these units serve as the primary source of power to equipment. In the case of a blackout, the UPS will continue to generate power, but will be unable to recharge. Choosing the right UPS When deciding what type of UPS to purchase, you should determine how much an unexpected power failure would impact your business.
Online units offer the most protection, since they run constantly.
The additional cost of these systems is often deemed worthwhile for key equipment where a shutdown is unacceptable. They are usually recommended for mission-critical applications such as phone systems or a computer server. Standby and line-interactive UPS are more appropriate when an unexpected power outage, and the resulting loss of data or other information, would be more of an inconvenience than a major problem. Line-interactive UPS are well suited for situations where power fluctuations are common occurrences. With line-interactive UPS, these fluctuations can be handled by the transformer instead of the internal battery.
