Description
This is a stay cool BUCK up down adjustible voltage converter that takes any power source or rail power AC, DCC or DC through the trucks of any G, K, O, HO, or N scale car of any type and provides a constant voltage for interior lighting of diodes or bulbs. (Bulbs not recommended due to heat they generate.) The grey wires are the connections to the source power and the red/black wire is the DC output with red being positive and black being negative.
