In summary, UPS Systems supply battery backup power to support equipment through blackouts. Select models feature automatic voltage regulation to correct incoming power without relying on UPS batteries. Surges and line noise can damage internal components in a single devastating event or slowly over time. UPS Systems use surge suppression and line noise filtering to guard equipment against potential damage. When power problems shut down equipment, valuable data is often lost. UPS Systems use battery backup power to allow enough time for data to be saved manually or automatically using FREE PowerAlert Software. The three main types of UPS Systems are Standby, Line-interactive and On-line. Standby UPS systems provide basic surge protection and battery backup. Line-Interactive UPS provide a higher level of protection from power problems by continually conditioning and regulating AC utility power. Finally, On-line UPS systems provide the highest level of protection from power problem by completely isolating sensitive equipment from every power problem on the AC power line.
