Vertiv Liebert PSI5 Lithium-Ion 1100VA Short Depth 2U Rack/Tower UPS provides the greatest power capacity in the smallest footprint in the market. The chassis is under 12 inches deep, which makes it ideal for smaller installations in 2-Post and wall mount racks. This short depth chassis is also ideal with 4-Post racks which frees up space behind the UPS which can be used for other networking gear sharing the same U space. The Rack/Tower convertible chassis is ideal when you have non-standardized install locations. Equipped with (6) NEMA 5-15R outlets and (2) programmable outlet segment, it provides flexible power distribution and management of connected devices. PSI5 Lithium-Ion provides greater runtime, has 3X the battery life, performs better at higher temperatures and increases the total cost of ownership over 50%. Remotely monitor and manage the UPS with PowerInsight and/or through the Intellislot with optional network management cards.Vertiv Liebert PSI5 Lithium-Ion 1100VA Short Depth 2U Rack/Tower UPS provides the greatest power capacity in the smallest footprint in the market.
