Money Saving Transformer Options

We have had great success with a 16V AC/4.5 Amp transformer available from:

MCI Transformers: P/N 4-06-8016 16V AC/ 6.25 Amps $19.95 from MCI Trans. Call them at 1-(800) MCI TRAN. (For this price, you will have to wire it up yourself and you should use a 1 amp primary fuse & 5 amp secondary breaker).

Most Digitrax authorized dealers have various transformers available to serve your needs. Contact your favorite dealer and find out what is available.

Many dealers offer transformer kits made by one of the following companies (These are build it yourself kits that come with everything you need including instructions.)

The PT- 6-2 includes a UL-listed transformer, Power cord, Fuse Holders, 1.5 amp fast-blow fuse, 5.0 amp fast-blow fuse, shrink tubing, output cable, complete instructions. Input 110V. Output 16V 6.25 amps. Part number PT-6 $35.00 MSRP. Order from your dealer or direct from Springhaven Shops (703) 327-6769.

General DCC Transformer Information

There are many transformers and power packs that can supply the input power for Digitrax boosters & command stations. Most regular DC train control packs do not have enough power to supply the full power potential of the a 5 or 8 amp booster, since they were designed to only run 1 locomotive in a blocked system. To get the full power potential you may hook up a suitable alternative transformer. Check with your local Digitrax dealer to see which transformers he has available.

Be very careful when you hook up your transformer to be sure that you do not create a shock or fire hazard. Many modelers have safely hooked up line transformers when creating their own conventional DC throttles, from one of the many "do it yourself" project articles. If you are not comfortable with the 110Volt input wiring, we strongly suggest you consult with an electrician.

1) Most important is to be sure the 110V input voltage is safely isolated from the low voltage secondary of the transformer. A properly installed safety ground will ensure that the layout cannot become a shock hazard if there is mis-wiring or insulation failure.

2) You must protect the primary and secondary windings of the transformer from overload. A typical primary protection would be a 1 amp "slow-blow" fuse (in an appropriate fuse holder) wired in the primary line circuit. For the secondary we recommend a circuit breaker rated no larger than the minimum of either the transformer secondary current rating or the booster's output current rating (typically 5 or 8 amps).
