Abstract

The invention relates to a device (9) for controlling the maintenance actuators (7a, 7b) of the cowlings of a turbojet engine nacelle of an aircraft, that comprises a first stage (12) to be connected to an electric power network (10) of the aircraft, at least one second power stage (13a, 13b) including converters of a first DC voltage from the first stage (12) into a second DC voltage for powering at least one maintenance actuator (7a, 7b) connected downstream from the device (9), a control means (14) for the first and second stages (12, 13a, 13b), and a means (15) for establishing a communication between the control means (14) and at least one control housing (16a, 16b) so that a user can control the operation of the actuators, the control means being arranged so as to carry out switching operations between a first operation mode in which the second stage(s) (13a, 13b) are powered, and a second standby mode in which the second stage(s) (13a, 13b) are not powered by the first stage (12).
