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 KA3, 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).
The WAUX-KA1 includes the auxiliary harness for the WOW101 sound decoder line with a KA1 Keep-Alive® device attached.
