NOTE: This product utilizes a specific plug harness which may not be compatible with all decoders. Refer to the Product Documentation for more information.
TCS KA Devices offer the following features:
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 and coming in at half the size of a KA3, the KA1 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 2-Pin Quick Connector Harness for plugging into decoders with a compatible socket. , such as the T4.
Decoder Specifications:
-
Size: 0.35 x 0.35 x 0.61 in (8.9 x 8.9 x 15.5 mm)
-
Connection: 2-Pin JST
-
Input Voltage: 12-16V
Keep Alive® Decoder Compatibility With TCS Decoders
TCS Keep Alive® (KA) devices are designed to operate with all TCS (or any other Keep Alive® ready) decoders. Decoders with a corresponding socket can be used with the KA1-P. This will be detailed in the decoder literature if the decoder has the socket.
!!!WARNING!!! Decoders with a “-KAC” suffix have a non-polarized 2-Pin Connector for attaching the KA(x)-C. The KA1-P is NOT compatible with this style of plug-in Keep Alive® interface.
Keep Alive® Decoder Compatibility With Non-TCS Decoders
If you would like to attach a Keep Alive® unit to a non-TCS decoder, you need to connect the wires across the output of the bridge rectifier on the decoder. You will need to consult your decoder manufacturer for a schematic or wiring diagram.
Installation Notes for TCS Decoders
1. ALL TCS decoders are compatible with Keep Alive® devices.
2. Connect the Keep Alive® wires to the decoder (Make sure you match the wire colors on the KA to same wire color on the decoder).
3. That’s it! Your locomotive is ready to run over the most treacherous of tracks.
