External 144 VDC battery cabinet for Liebert UPS

The Liebert GXT4-144VBATT is a 144 V DC external battery cabinet built for rack or tower mounting. It supports the Liebert GXT3-5000RT208, GXT3-6000RT208, GXT4-5000RT208 and GXT4-6000RT208 UPS systems. The unit uses valve-regulated lead-acid cells rated at 9000 mAh in a spill-proof design.

Passive thermal design with no active cooling

The cabinet contains no fans or pumps, so it adds no audible noise to the rack. Heat dissipates through the metal enclosure during normal float or discharge cycles. Power draw is limited to the UPS charging current, with no separate mains input required.

Rack slide kit and short interconnect cable included

A RMKIT18-32 slide kit allows the 3.30 x 26.10 x 16.90 inch cabinet to mount in standard 18 to 32 inch deep racks. The 1.5 foot interconnect cable links the cabinet directly to the compatible UPS. Internal batteries are pre-installed and ready for connection.
