The Tripp Lite BP288VEBP 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. Not only does it provide 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.
