Tripp Lite's SMART 3000VS intelligent, line interactive UPS with expandable runtime protects server, networking and telecommunications equipment from blackouts, voltage fluctuations and transient surges. Small footprint, tower UPS system occupies only 106 square inches of floorspace with a height of only 14.25 inches. Large capacity 3000 VA/2250 watt rated UPS system offers 4 minutes runtime at full load and 14 minutes at half load during power failures. Runtime is expandable with optional external battery packs. Line interactive voltage regulation corrects brownouts as low as 79V and overvoltages as high as 147V to fully regulated 120V nominal output for smooth continuous operation of connected equipment. Includes a total of 10 outlets, 3 of which can be individually powered off and back on via software interface to selectively reboot remote equipment or shed less critical loads to extend battery runtime for more critical loads. Includes slot for internal SNMPWEBCARD, plus 2 DB9 and 2 USB enhanced monitoring ports for unattended shutdown, remote control and monitoring of UPS system and power data. Ships in attractive gray color scheme. Compatible with Tripp Lite's PowerAlert and Watchdog service software.
What does Uninterruptible Power Supply (UPS) mean?
An uninterruptible power supply (UPS) provides nearly instantaneous power when the main utility power source fails, allowing either time for power to return or for the user to shut down the system or equipment normally by closing running computer system applications and using the operating system to shut down the system. The user has between five and 15 minutes to shut down a system normally or bring an auxiliary power source online to restore the power supply. In addition, most UPS systems also work to address power source electrical surges, sag voltage, voltage spikes, frequency instability, noise interference or harmonic distortion from the ideal sinusoidal wave form. If you're concerned about power failures, especially if you've lost work on your computer due to power outages in the past, you should buy a UPS. A UPS combines a surge suppressor with a big battery, and has special circuitry that detects a power failure and quickly switches over to run your equipment on its battery. The sole purpose of a UPS is to give you a few minutes at the start of a power failure to do two things:
-Save your work, and
-Shut down your computer.
A UPS is not designed to let you continue to use your computer for hours and hours until the power comes back on. If properly chosen, a UPS will give you 5 to 10 minutes (possibly more) to Save and do an orderly Shutdown.
