Did you know?
T1kVA and T1.5kVA Tower UPS units feature Advanced Battery Management (ABM) technology that uses
a unique three-stage charging technique that significantly extends battery service life and optimizes
recharge time, compared to traditional charging.
T1kVA and T1.5kVA Tower UPS units can enhance system availability with individual receptacle groups or
load segments that can be programmed and controlled, which allows mission-critical devices to be
prioritized during shutdown to preserve battery run time if there is a prolonged power outage.
T1kVA and T1.5kVA Tower UPS units come standard with UPS Power Manager (UPM) power management
software that integrates seamlessly with the major virtual platforms, which enables you to view and
manage your entire power system from your current dashboard. It also triggers live migration during power
outages and avoids data loss by gracefully shutting down virtual machines and hosts in a cluster if there is
an extended power outage.

Features
A UPS is a device that acts as a defensive barrier between electronic equipment and incoming power
problems. It conditions, regulates, and filters out power disturbances to ensure a clean power source for IT
equipment. A UPS also provides battery backup if there is a power failure.
In today’s high availability server environments, unplanned power outages or line quality irregularities can
have a considerable financial effect on all sized businesses. The typical utility power is 99.9% available, but
that means that there can be almost 9 hours of downtime a year, which includes brownouts and other
power quality problems.
Selecting the right UPS can help protect against these potentially costly incidents.
The T1kVA and T1.5kVA Tower UPS units are most effective against five power problems: power failures,
power sags, power surges, under-voltage, and over-voltage.
The T1kVA and T1.5kVA Tower UPS models offer the following features:
High-efficiency protection delivers more real power (watts) in a compact design, lowering power,
and cooling consumption
Graphical Liquid Crystal Display (LCD) provides intuitive configuration, management, and monitoring
capabilities in the following languages to reduce management complexity:
English
French
German
Spanish
Russian
Portuguese
Italian
Hot-swappable batteries for maximum uptime, availability, and ease of maintenance
Standard UPS Power Manager software provides effective local or remote power monitoring and
management for servers and virtual machines and allows for graceful remote system shutdown
ABM technology significantly extends battery service life and optimizes recharge time
Load segments for individual control of receptacle groups to manage sequential shut downs and
start ups and reserve battery run time for the most critical equipment
Optional NMC for enhanced UPS monitoring and control over-the-network through a standard web
browser
Optional Environmental Monitoring Probe for thermal management requirements (temperature and
humidity)
Allows dual channel communication through the USB or RS-232 port and an optional NMC at the
same time to maximize communications flexibility
Remote flash upgradeable firmware for the UPS and NMC, which makes it an ideal solution for
remote locations
Includes a Remote On/Off (ROO)/Remote Power Off (RPO) port to control power of the UPS unit
through a wired remote switch
