TSU-750 for N and some HO


All the Tsunami range have these common features:

  • Long and short addressing
  • Supports 14, 28, and 128 speed step modes
  • Speed interpolation provides smooth 128 speed step response in any mode
  • Programmable acceleration, deceleration & start voltage
  • Stadard and advanced consisting
  • 15 pre-programmed speed tables and 1 user programmable speed table
  • High Frequency Silent Motor Drive
  • Load Compensation
  • Supports 14, 28, and 128 speed step modes

    Tsunami AT1000

     Soundtraxx produce 3 forms of board replacement decoder.  They are board replacements for Atlas (AT), Athearn Genesis (GN) and Kato (KT) HO diesels.

    Other than the physical format the specification of these decoders is the same as the TSU 1000.

    Tsunami-750

    The TSU-750, Micro Tsunami, is the little brother of the series.  The sound capabilities are the same as the TSU-1000 but it is less powerful as a loco decoder.   The maximum stall current is lower than most decoders and special care must be taken to check the loco's current usage.
