Connect your PowerHouse Power Supply directly to the track with the TMCC Direct Lockon. It features a selectable current setting (for both the 135 watt or 180 watt PowerHouses Power Supplies). The Direct Lockon eliminates the need for a PowerMaster if you run only TMCC equipped locomotives. For added safety, the Direct Lockon provides over-current protection and an automatic reset. It is compatible with both Lionel FasTrack and O/O27 track systems. It includes power wire with FasTrack connectors and one standard Lionel Lockon.
