TCS #2001 KA3 Keep Alive® With 2-Pin Quick Connector Harness for power.
With 2-Pin Quick Connector Harness for power.
The 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 KA3-C will power an HO-Scale locomotive with headlights on for approximately 6 to 20 seconds (depending on the locomotive and the effciency of the motor). This KA3-C will work with Keep Alive® ready decoders and most non-TCS decoders. TCS decoders manufactured after February 2012 are Keep Alive® ready.
