How to hook up and run your trains:
To Run Trains on DC power:
  1. Attach an AC grounded power cord to the power supply
  2. Attach 18 guage wires between the supply and our SL-TLC1cv DC throllte
  3. Attach wires between the SL-TLC1cv and your track.

This combination provides 200VA of power and 24VDC PURE LINEAR POWER at 6 Amps continuous/8.3 amps peak. Maximum power supply output voltage can be adjusted from 18.4 to 27.4 Volts DC by turning the adjustment control on the supplys front pannel. (see photo below)

The power supply is perfect for use with our TLC1 Throttle shown above with track clips in our SL-PS200-1-27&TLC1 SET (click her to view). The +V Adj contol on the font pannel makes this the perfect 8.3 amp 17.4 to 27.4 Volt DC Power supply for DC or DCC (MTS) power.

To Run Trains on MTS/DDC power:

  1. Attach an AC grounded power cord to the power supply. (see optional cord above)
  2. Attach two wires between the supply and your DCC central station or booster (Massoth DiMAX 800Z shown).
  3. Attach wires between the DCC central station or booster and your track.
  4. Plug in the power supply
