Blackouts and brownouts (low voltage) shut down equipment which results in downtime, damage, and data loss. 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 feature 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 feature battery backup power to allow enough time for data to be saved manually or automatically using FREE PowerAlert Software.
