A word of caution regarding using HO DC supplies:

A typical small HO supply uses a series rheostat (variable resistor) to drop the output voltage. That means that the actual output voltage depends upon how much current is being drawn. For a mimimal load, the first step when turning up the knob may produce almost the full rated output voltage!
