The PowerSure PSP from Liebert is a compact, full featured 
UPS that delivers cost-effective power protection. Designed 
with simple controls for easy operation, the PowerSure PSP 
provides over four minutes of battery back-up at full load —
more than enough time to save work in process and shut 
down your system.
Perfect for desktop applications, the PowerSure PSP 
provides one-on-one power protection for PCs and  
other sensitive electronic equipment. Two models 
available: 350 and 500VA at 120VAC and 500 and 
650VA at 230 VAC.
For maximum flexibility, a choice of communications 
options are available — USB, serial or contact closure. This 
option solves the legacy systems dilemma of what to do 
with equipment that does not have USB capabilities. A 
MultiLink
™
 automated shutdown software CD, serial 
communications cable and USB cable are also included.
