The Vertiv™ Liebert® PSI5 line interactive UPS family provides network grade uninterruptible power protection with pure sinewave output power and automatic voltage regulation ensuring availability of critical systems and information. Reliable and efficient power protection for servers, network equipment, medical devices, point-of-sale (POS) devices and security systems.

The flexible design of the Liebert® TAA-compliant PSI5 allows the UPS to be configured as a self-standing tower or to be rack-mounted within a 2U space. It is available from 1500VA to 3000VA for 120V applications. The Liebert® PSI5 UPS features an innovative advanced line-interactive design incorporating both boost and buck Automatic Voltage Regulation (AVR) technology. This protects connected equipment against utility voltage fluctuation (sags and surges) by automatically increasing or decreasing utility voltage levels, as required. It also helps prolong battery life by minimizing the amount of time that the UPS needs to operate on-battery to protect the equipment. Models with a capacity of 1500VA and below are not for sale in Vermont, Colorado, Washington.
