Track Power Control - Multiple Power Supplies Copyright (c) 2006-2007 by Steve Sawtelle - All Rights Reserved. Copyright (c) 2006-2007 by Slot Car Corner L.L.C. - All Rights Reserved.   Most home layouts employ a single power supply to provide track power; however, some layouts are designed and wired with multiple power supplies.  There are any number of reasons why this might be done - for example, when the rated output current for a single power supply is not adequate for all lanes given the types of cars/motors being raced.  If you use a PC-based race management system to control track power, you will need to ensure the power supplies are wired in such a way that the race management system can manage all of them simultaneously.   The links below show examples of how to wire two (2) or four (4) power supplies so they can be managed by a single race management system.  In the first example, the 2 power supplies are providing power to a four (4) lane track - each power supply powers 2 lanes.  In the second example, the 4 power supplies are also providing power to a 4 lane track - each power supply provides power to one lane.  The diagrams were developed specifically for the Trakmate for Windows race management system; however, these basic wiring principles can be applied to other race management systems as well.   High quality track power control products such as call buttons, terminal blocks, and power relays are available in the Online Store.   Controlling Two (2) Power Supplies Controlling Four (4) Power Supplies     You will need Adobe(R) Acrobat(R) Reader software to view the diagram.  Acrobat(R) Reader is free - you can download it from the Adobe(R) website by clicking on the icon below.
