KA2

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).

 

This Keep-Alive® includes a blue and a black w/ white stripe wire with which to attach it to a decoder.
