Abstract
A controller for electrically adjustable furniture includes a main-voltage area and a low-voltage area that are electrically isolated from one another. A rectifying power supply unit, which is located in the main-voltage area, serves to generate a rectified voltage available at power supply terminals from an alternating main voltage. The rectified voltage present at the power supply terminals can be delivered to a first motor terminal located in the main-voltage area depending on a first control signal. The controller furthermore includes a first control unit that is located in the main-voltage area and which incorporates an operating terminal and a first control output for the supply of a first control signal. An operating unit located in the low-voltage area is connected via an electrically isolating coupling to the operating terminal.
