Designed for a 28V electrical bus, the TS28 Emergency Battery Power Supply (EBPS) provides DC power for aircraft loads, such as emergency lighting and other critical equipment when main aircraft power fails. The unit can be fully recharged or maintain existing full charge, via the aircraft’s primary power bus.
The TS28 EBPS is designed to provide power to emergency lighting in Citation 550, 560, 680, 680A and 700 aircraft models, and is a direct replacement for Radiant Battery Power Supplies CBS28-1. The TS28 delivers superior quality, longer lifespan, and cell-swapping capabilities that reduce cost for these aircraft operators.
