N Scale DCC Keep Alive

These are the smallest DCC Keep Live boards made. They offer the best options for improving operations of N Scale locomotives. These do not provide the level of Keep Alive that can be installed in larger locomotives.

  • Smallest DCC Keep Alive foot prints
    • 470uF model is 9.5mm W x 9.8mm L x 3.9mm H
    • 840uF model is 9.5mm W x 9mm L x 5.6mm H
  • Expandable by easily adding parallel external capacitors
  • Easy to program when installed. Will program like a normal decoder when connected to a Lok Programmer, or a Soundtraxx PCB-100 Booster
  • 14V maximum track voltage
    • Over voltage protected
  • For best results the 470uF should be used with an external 470uF capacitor for a total capacitance of 940uF
  • These do not provide the level of Keep Alive that can be installed in larger locomotives.
