TCS Keep-Alive® (KA) devices are used to supply power to decoders during times of power interruption due to dirty track or problematic track work.

Newly-redesigned with a smaller overall footprint, the KA1 will power HO or N scale locomotives with approximately one-third of the capacitance of KA3/KA4 devices (depending on the locomotive and motor).

Included is one replacement auxiliary harness for the WOWSound decoder line with a KA1 Keep-Alive® device attached.

KA1 Dimensions: 1.063" x 0.35" x 0.244" or 27mm x 8.9mm x 6.2mm
