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 at half the size of a KA4, the KA2 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 KA2 Keep-Alive® device attached.

KA2 Dimensions: 0.35" x 0.35" x 0.61" or 8.9mm x 8.9mm x 15.5mm
