Document Type and Number:
WIPO Patent Application WO/2013/034475
Kind Code:
A3
Abstract:
A control means comprises a control part (3) which is designed to actuate an electrically adjustable item of furniture, and a switched-mode power supply unit (2) which supplies power to the control part (3). The switched-mode power supply unit (2) has a switched-mode regulator module (223) for controlling the switched-mode power supply unit and can be switched to a normal operating state and to an inoperative state. The switched-mode power supply unit (2) is designed to provide a supply voltage for the switched-mode regulator module (223) in the inoperative state in a manner clocked by a start-up circuit (224). The switched-mode power supply unit (2) has a supply system failure identification circuit (230) which is designed to detect failure of a supply system voltage, which is applied to the input end of the switched-mode power supply unit (2), on the basis of a signal in the start-up circuit (224) and to indicate this to the control part (3).
