PSI
High Performance Rack-Mount 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.
Liebert PSI allows you to get more from your UPS and your protected
equipment, with features normally found only on more expensive systems:
Up to five minutes of internal battery backup time at full load
provides ample time for an orderly shutdown of connected equipment.
Liebert PSI operates at a higher output power factor — meaning less
power consumption. This results in your network running at lower
power levels and lower heat levels, and ultimately provides a longer
network service life.
Remote communications and shutdown options provide remote
monitoring and power management — contact closure, USB, SNMP
Liebert PSI is compliant with the Restriction of Hazardous
Substances Directive (RoHS), prohibiting use of six hazardous
materials manufacturing of electronics, including lead-free solder.
Ideally suited for:
PCs
Network workstations
Servers
Network closets
Large network peripherals
