Tripp Lite SU8000RT3UN50 8000VA / 8kVA / 7200 watt online, double-conversion UPS system offers complete power protection for critical network applications. This system delivers online, double-conversion UPS protection with zero transfer time, suitable for advanced networking applications. Fault-tolerant auto-bypass prevents unexpected service interruptions during UPS overload or internal fault conditions. Included detachable PDU with manual bypass switch enables hot-swappable replacement of entire UPS power module with no interruption to connected equipment. Enhanced availability, fault tolerance and simple hot-swap replacement options make this UPS ideal for advanced networking applications in data centers, computer rooms, network closets and rugged industrial applications. Cold-start operation supported. Optional economy mode enables high efficiency bypass operation with a maximum output voltage variation of +/-10%. Double conversion mode is automatically restored as mains voltage varies beyond +/-10% with less than 1 millisecond transfer time between modes.
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.
Please Note: 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.
