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 KA1 will power HO or N scale locomotives with approx. 30% of the capacitance of KA3/KA4 devices (depending on the locomotive and motor).
The KA1 will power an HO-Scale locomotive with headlights on for approximately 2 to 5 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.
Dimensions: 1.063″ x 0.35″ x 0.244″ or 27mm x 8.9mm x 6.2mm
