Tripp Lite SU3000RTXLCD2U Smart Online UPS systems offer high performance power protection ideal for critical server and network equipment in datacenters, computer rooms and network closets. Online, double-conversion Uninterruptible Power Supply (UPS) maintains perfectly regulated output power by continuously converting raw AC input to DC, then re-converting output back to AC. Fully regulated sine wave AC output with +/-2% voltage regulation powers network equipment continuously, even during severe brownouts and overvoltages, all without depleting UPS battery reserves. Maintains battery-derived AC output during power failures with zero transfer time. Extended runtime options available. Interactive LCD interface reports UPS operating mode, detailed UPS and site-power data, plus enables a variety of UPS setup and configuration options. Up to 99% efficiency with economy mode option saves BTU heat output and energy costs. Network management interfaces support communications via USB, RS-232, contact-closure and optional SNMPWEBCARD network interface. Built-in DB9 port offers both enhanced RS-232 data and basic contact closure monitoring ability. HID-compliant USB interface enables integration with built-in power management and auto shutdown features of Windows and Mac OS X. Includes PowerAlert monitoring software and complete cabling. Emergency Power Off (EPO) interface. LED display reports UPS operating mode, line power availability, battery mode operation, inverter operation, ECO mode status and output power availability. Audible alarm with push-button momentary alarm-cancel and silent-mode LCD configuration options. Frequency regulation and conversion options for all 50/60Hz applications. Programmable self-test. Battery independent restart. Fault-tolerant auto-bypass mode. Field-replaceable, hot-swappable internal batteries and external battery packs.
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.
