+/-144VDC UPS Battery Backup Replacement —You Provide the Batteries
This special configuration includes the steel enclosure and all required internal wiring and installation accessories for a user-provided quantity of 96 12V 9Ah internal batteries (batteries not included). For the same battery pack with internal batteries included, see Tripp Lite’s BP288VEBP.
Gives Your Compatible UPS System Extended Runtime
This best UPS battery replacement is compatible only with Tripp Lite’s 3-phase 208V SUT20K, SUT30K, SUT40K, SUT60K and other UPS systems that specify the use of this battery pack. After you buy and install your own batteries, the BP288VEBPNB not only provides extended runtime, but it can also be daisy-chained to additional external battery packs for even longer extended-run operation. The three-pole input/output terminal blocks allow safe, simple hardwire installation, as well as internal disconnect for battery isolation.
Rugged Steel Construction Designed to Last in Busy IT Applications
The steel cabinet features front and rear doors that provide easy access to the user-supplied internal batteries and the input/output terminal blocks. A 250A circuit breaker protects your equipment from dangerous overcurrent or overloads, while 63A fuses guard each battery string. Pre-installed rolling casters allow you to move the cabinet smoothly to its intended destination. Use the adjustable levelers for secure deployment on a stable surface.
One-Year Warranty
The BP288VEBPNB is backed by a one-year warranty, ensuring reliability and performance.
