Product Model


At 3000VA/2700W capacity, the Liebert® PSI5 Lithium-Ion short depth UPS provides the greatest power capacity with the shortest depth chassis in the market. The chassis is 16.9 inches total depth and only 15.7 rackmount depth which makes it ideal for smaller installations with wall mount and 2-Post racks. This compact UPS is also suited for 4-Post racks which frees up space behind the UPS to be used for other networking gear in the same U space. It is ideal when you have non-standardized install locations.
