To Run Trains on DC power:
  1. Attach an AC grounded power cord to the power supply.
  2. Attach 18 gauge wires between the supply and 1 or 2 SL-TLC1cv DC throttle.
  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/12.5 amps peak. Maximum power supply output voltage can be adjusted from 17.8 to 27.2 Volts DC by turning the adjustment control on the supply front Panel. (See photo below)

The power supply is perfect for use with our TLC12 Throttle shown above with track clips in our SL-PS300-1-27F&TLC12F SET (click her to view). The +V Adj. control on the font panel makes this the perfect 13 amp 17.8 to 27.2 Volt DC Power supply for DC or DCC (MTS) power.
The power supply power two or three TLC8F Throttles shown above with the use of circut breakers on each throttle. The SL-PS300-1-27F SET (click her to view). kit includes all the items shown above, just add wire and track clips and your ready to run.

To Run Trains on MTS/DDC power::

Attach an AC grounded power cord to the power supply.

  1. Attach two wires between the supply and your DCC central station or booster (Digitrax DCS 200 shown).
  2. Attach wires between the DCC central station or booster and your track.
  3. Plug in the power supply

The SL-PS320-1-27F power supply is a perfect match to the Massoth 1210Z and 1203 B 12 amp booster to provide 12 amps of continuous DCC power. The supply may also be used with other DCC central stations and boosters.

SL-PS320-1-27 13 Amp Power Supply
Massoth 1210Z Central Station
= 12 amps of pure MTS/DCC power

For all NMRA DCC AND LGB type I, II and III products

The Massoth 1210Z 12 amp central statioin and the SL-PS320-1-27 power supply is a perfect match for MTS/DCC use. The Massoth 1210Z is available at the Shourt Line now and comes with a USB port for PC control and firmware updates for all massoth products.

Need more than 12 amps of track power, use a 2nd SL-PS320-1-27 and a Massoth 1203B booster to add 12 additional amps of power to your layout.
