Soundtraxx CurrentKeeper

Improve the electrical performance of your model locomotives with SoundTraxx CurrentKeeper modules, now available at TrainSupply. CurrentKeeper boards use intelligent capacitor storage to help maintain smooth operation, reduce stalls and glitches, and support consistent power pickup — especially in challenging track conditions or models with heavy lighting and sound loads.

These modules help enhance the reliability of your DCC system by buffering power during momentary voltage loss and improving overall motor and accessory behavior.
