Abstract
An aircraft solid state power controller for controlling the supply of electric power from an aircraft electric power supply to an electric load comprises a power input node, which is electrically connectable to an output node of the aircraft electric power supply; a power output node, which is electrically connectable to an electric load and configured for selectively supplying electric power to the electric load; an electric load switch, which is configured for controlling the supply of electric power from the power input node to the power output node; a shunt resistor, which is arranged between the electric load switch and the power output node so that any electric current that is supplied from the aircraft solid state power controller via the power output node to the electric load passes through the shunt resistor; and a control device comprising a voltage sensor that is configured for detecting a voltage drop over the shunt resistor.
