Abstract:
1. A controller for electrically adjustable furniture, the controller comprising: a main-voltage area and a low-voltage area that is electrically isolated from the main-voltage area; a rectifying power supply unit located in the main-voltage area and which generates a rectified voltage at power supply terminals from an alternating main voltage; a first motor terminal located in the main-voltage area and to which, depending on a first control signal, the rectified voltage present at the power supply terminals can be delivered; a first control unit located in the main-voltage area and which includes an operating terminal and a first control output for the supply of the first control signal; and an operating unit located in the low-voltage area and which is connected via an electrically isolating coupling to the operating terminal of the first control unit.
