Universal Voltage Reducer (AC/DC)
Capable of lowering a power pack's top voltage output by 4 volts
If you've been having top voltage issues, here's a solution. The Universal Voltage Reducer lowers the top voltage output of the unit by approximately 4 volts. It works for any gauge and is especially useful with N Scale applications where top speeds are too fast. Installs in series between the power source and the track.
