1669 Keep-Alive® device – #TCS-KA5



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.


The KA5 includes an additional fifth supercapacitor, increasing the maximum capacity and peak charging voltage compared to a KA3 or KA4. The KA5 will power an HO-Scale locomotive with headlights on for approximately 6 to 20 seconds (depending on the locomotive and the efficiency of the motor).


This Keep-Alive® includes a Blue and a Black w/ White Stripe wire to attach it to a decoder.
