Using a TMCC Direct Lockon

The Lionel 6-34120 TMCC Direct Lockon is a fast acting electronic circuit breaker designed to protect the track from spikes and shorts cause by derailments.
Originally desigend to be used with Lionel Powerhouse AC supply it will work with any AC transformer providing 15-18 volts.

So if you are using a older transformer to power your TMCC layout you can add a TMCC Direct Lockon between your track and the transformer's Fixed or variable outputs as long as the output voltage is set to 15-18 volts.

You will also need the Power Adaptor Cable 6-12893 if using a transformer for power.

It can also be used to help protect a Powermaster by using it between the Powerhouse (or supply transformer) that powers the Powermaster
