Abstract: Apparatus (230) for controlling over-current from a power supply (110) to a device (250), the apparatus comprising two power supply inputs (232a, 232b) and two respective device outputs (234a, 234b), a control circuit (120) having control inputs (126x, 126y) connected across a variable resistance circuit (240) coupled between a said power supply input (232a) and a said respective device output (234a), the control circuit arranged to disconnect one of the power supply inputs (232a) from the respective device output (234a) in response to detecting a predetermined over-current voltage across the variable resistance circuit (240), the resistance of the variable resistance circuit (240) being varied dependent on an over-current setting signal (270) received from the device (250).
