The Series 3 UPS primarily protects against three of the nine power problems: power failures, power sags and power surges. This essential, cost-effective protection is necessary to prevent damage such as data loss, file corruption, flickering lights, hardware issues and equipment shutoff. For example, if the utility fails, you could lose all your work-in-progress. The Series 3 UPS offers a degree of protection against the remaining power problems and is most commonly used to protect single workstations and point-of-sale (POS) equipment.
