This AC-DC/DC- AC design ensures an increased degree of isolation of the load from the irregularities on the main supply. When it comes to safeguarding critical IT loads, only online double conversion technology protects fully against all these power problems, providing the highest levels of security for networks.Īn online UPS system is usually called double conversion as well because incoming power is converted to direct current (DC) and then converted back to AC. But during transmission and distribution, it is subject to voltage sags, spikes and complete failure that may interrupt computer operations, cause data loss and damage equipment.
These UPS systems are defined by how power moves through the unit.ĪC power is stable and clean upon generation. The three major types of UPS system configurations are online double conversion, line-interactive and offline (also called standby and battery backup). The load size, location and criticality of the equipment to be protected are key, as well budgetary considerations, when choosing a UPS for power backup. Selecting a UPS for your particular application requires an examination of a number of factors.
Each technology has its advantages and each may be necessary for configuring cost effective power protection, especially in complex systems. All three basic uninterruptible power supply (UPS) technologies have their place in protecting today’s distributed IT infrastructure especially on the network edge.
