Abstract
A power regulation device and method for a model railway system is provided. The device comprises inputs that connect to a supply of a digital command control (DCC) waveform and to a track section to be powered by the DCC waveform. The device comprises a current measuring circuit that measures current flow associated with the DCC waveform supplied at the inputs. A switch is connected between the inputs and outputs that are in turn connected to respective rails of the track section. A controller is provided that analyzes a current measurement signal produced by the current measuring circuit and controls the switch to disconnect supply of the DCC waveform to the outputs when a true over-current condition is detected. The device may also comprise an auto-reversing function to accommodate reverse loop track sections.
