SU6000RT3U product image


Tripp Lite SU6000RT3U on-line, double-conversion UPS protects server, networking or telecommunications equipment from blackouts, voltage fluctuations and surges in a compact tower/rackmount housing. In a rack configuration, the power module, step-down transformer, and battery pack occupy only 3 rack spaces each (9U total). Upright tower placement of entire system supported with included tower stands. Large capacity 6000VA/4200 watt power module double-conversion technology converts raw input AC to DC, then resynthesizes it back to perfect sine wave AC output within 2% of user-selectable 208V/240V and 120V AC output voltages. Frequency regulation locks output power to 50/60Hz (+/-0.2 Hz), removing harmonic distortion, fast electrical impulses and other hard-to-solve power problems not addressed by other UPS types. Perfectly regulated, continuous sine wave output with zero transfer time offers guaranteed uptime and compatibility with all equipment types. Hardwire input and output connections support a variety of permanent or plug-in power connections. Highly efficient operation in optional economy mode setting, saving BTU heat output and energy costs. Battery support can be extended through the addition of external battery packs. Includes accessory slot for optional monitoring and management cards, plus DB9 contact-closure, and DB9 enhanced serial monitoring ports for unattended shutdown, remote control and monitoring of UPS system and power data.

Questions & Answers

Tripp Lite offers Hot-Swap PDUs, which make any UPS hot-swappable, as well as Hot-Swappable Modular UPS Systems, which integrate a detachable Hot-Swap PDU. The key component of the hot-swappable design is a modular power distribution unit (PDU) that combines all input and output power connections with a manual bypass switch. The dual input and manual bypass features of the PDU enable UPS system maintenance–from battery replacement to complete power module exchange–without powering down connected mission-critical equipment and hiring costly service specialists.

In Economy Mode, the UPS increases efficiency by implementing dynamic double conversion, which means it suspends or resumes double conversion automatically as the quality of input power changes. For a full explanation of Economy Mode, click here
