Abstract
A signal converter and method of converting a signal are provided. The converter includes a power supply, microcontroller and current sensor. The microcontroller is connected to a power supply and is configured to receive inputs from a vehicle and output signals to loads of a second vehicle. The sensor is connected to the microcontroller to monitor current flow at the loads. The output channels are configured to stagger activity on the output signals. The microcontroller reduces the duty cycle of the output signals if the current flow rises above a first threshold and resumes the output signal to full strength once the current flow falls bellow a second threshold. The method includes receiving an input signal, sending an output signal, measuring current flow, measuring temperature, reducing the power of the output signal, and restoring the output signal.
