UPS (Uninterruptable Power Supplies) are a highly recommended soluion for Servers and Critical workstations. The UPS has power conditioning capabilities, giving clean synthesized sine wave power removing both power surge spikes and brown outs ( when power source AC power drops below 105 volts), these two power conditions can corrupt data being written to the computer, and brown outs can also damage components within the computer or server. The secondary function is during brown outs to add from the battery source the additional voltage to bring the ac power into the 110-120 volts range. The third feature is during brief power outages (30 seconds or less) is to instantly switch to battery created AC power and maintain the computers ongoing uninterrupted operations, then switches back automatically as soon as power is restored. Then it goes back to running the computer via the filtered incoming AC power as well as beginning to recharge the battery which was used during the brief power failure. Then in event of a prolonged power outage the UPS has software and a port connected to the Server/Workstation where it will do an orderly shutdown of that Server/Workstation (protecting the data and operating system from corruption) in the event that power is not restored. Then when power is restored the battery will be recharged.
