The flexible design of the Liebert® PSI5 allows the UPS to be tower (MT models), 1U rack mountable (1U models), or to be configured as a self-standing tower or to be rack-mounted within a 2U space (RT models). It is available from 750VA to 5000VA with both 120V or 208V models. The Liebert® PSI5 UPS features an innovative advanced line-interactive design incorporating buck/boost Automatic Voltage Regulation (AVR) 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. Models with a capacity of 1500VA and below are not for sale in Vermont.
