Patent ID: 8767363

Claim:
A power module for use in supplying power from a power source to a power consuming unit, the power module comprising: at least a first and a second power input means configured to input power to the power module, wherein the first and second power input means are connected to the power source; power output means configured to output power from the power module to the power consuming unit; first power feeding means connected between the first power input means and the power output means; second power feeding means connected between the second power input means and the power output means, wherein the first power feeding means comprises first circuit breaking means configured to limit high currents flowing from the power source through the first circuit breaking means and through the power output to a current lower than a current causing a voltage drop at the power source by disconnecting the first power feeding means from the power source; wherein the second power feeding means comprises second circuit breaking means configured to limit high currents flowing from the power source through the second circuit breaking means and through the power output to a current lower than a current causing a voltage drop at the power source by disconnecting the first power feeding means from the power source; wherein the first circuit breaking means and the second circuit breaking means further comprises register means configured to register if the first and second circuit breaking means have disconnected the first and second power feeding means respectively; and wherein the first and second circuit breaking means are further connected to a controller, the controller being configured to read the register means.
