PB5 or PB105

The PB5 only has two voltage settings: 13.8v for HO scale / 12V for N-scale. It comes with its own switching DC power supply.

The PB-105 has a potentiometer that allows for a broader range of output voltages but it does not come with its own power supply.   

If you are in HO-scale or N-scale and have NOT changed the output voltage of the PH-Pro system box then the PB5 will work just fine.
