3000VA / 3kVA / 2500 watt on-line, double-conversion UPS system for critical server, network and telecommunications equipment. 2U rackmount form factor with an installed depth of only 26 inches (66cm). Full time sine wave 100/110/115/120/127V output with +/-2% voltage regulation. Uninterruptible Power Supply (UPS) actively converts raw incoming AC power to DC, then re-converts output back to completely regulated, filtered AC output. Operates continuously without using battery power during brownouts to 70V and overvoltages to 144V. Up to 97% efficiency in optional economy mode saves BTU heat output and energy costs. NEMA L5-30P input plug. NEMA L5-30R, NEMA 5-15/20R and NEMA 5-15R output receptacles. Network-grade AC surge and noise suppression. Zero transfer time between AC and battery operation. Network management interfaces include USB port, DB9 serial port and SNMPWEBCARD slot. Built-in DB9 port offers both enhanced RS-232 enabled monitoring data, plus 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. Supports simultaneous detailed monitoring of equipment load levels, self-test data and mains power conditions via all network interfaces. Includes PowerAlert monitoring software and complete cabling. Emergency Power Off (EPO) interface. Integrated two bank PDU switching supports automated load shedding and remote-reboot of connected equipment. Multi-stage metered current monitoring and battery charge status LEDs. Mains power and voltage regulation LEDs. Audible Alarm. Self-test. Fault-tolerant auto-bypass mode. LED display panel easily rotates for better viewing in rackmount or tower configurations. Includes 4 post rackmount accessories. 2-9USTAND tower kit and 2POSTRMKITWM two post rackmount hardware accessories available.
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.
