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 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.
0.35″ x 0.35″ x 0.61″ or 8.9mm x 8.9mm x 15.5mm
*Please consult your decoder manufacturer for compatibility with other devices.
COVID-19 INFO: Arizona has issued an ordinance for us to shelter in place through the end of April. Orders will be accepted and processed, hopefully, with no change in service. Thank you for your patience! Dismiss
