PSI
High Performance Rack & Tower UPS For Network Power Protection
Liebert PSI is a compact, line-interactive UPS system
designed especially for IT applications such as network
closets and small data centers. It provides reliable
power protection for servers, critical nodes, network
workstations, large network peripherals, network
routers, bridges, and other electronic equipment.
The flexible design of Liebert PSI allows the UPS
to be configured as a self-standing tower or to be
rack-mounted within a 2U space. It is available in five
capacities, and both 120V or 230V models.
The UPS features an innovative line-interactive design
incorporating buck/boost automatic voltage regulation
technology. This protects against utility voltage fluctuation by
raising and lowering utility power to the level needed by the
connected equipment. It also allows the UPS to prolong battery
life by maximizing its time on utility power before going to battery.
