Providing outstanding performance and reliability, the Eaton 9355 UPS's unique benefits including the
following:
l
Online UPS design with pure sine wave output. The UPS filters and regulates incoming AC power and
provides consistent power to your equipment without draining the battery.
l
More wattage in less space with a 0.9 power factor – protecting more equipment and leaving more room for
expansion.
l
A UPS maintenance bypass switch (MBS) that provides a Make-Before-Break (MBB) wrap-around bypass for
UPS maintenance or service without shutting down the load.
l
Support for Powerware Hot Sync
®
paralleling of multiple modules for redundancy or extra capacity.
l
Input current total harmonic distortion (THD) of less than five percent, using active input power factor
correction.
l
ABM
®
technology that uses advanced battery management to increase battery service life, optimize
recharge time, and provide a warning before the end of useful battery life.
l
Over two hours of extended runtime with added EBCs.
l
Advanced power management with the Software Suite CD for graceful shutdowns and power monitoring.
l
Emergency shutdown control through the remote emergency power-off (REPO) port.
l
Start-on-battery capability for powering up the UPS even if utility power is not available.
l
Standard communication options with a DB-9 serial port, relay output contacts, and programmable signal
inputs.
l
Optional X-Slot
®
cards with enhanced communication capabilities for increased power protection and
control.
