Patent

CA 2657889

The invention relates to a control for electrically adjustable furniture, comprising a mains voltage region (1) and a low voltage region (2), which are electrically separated. A rectifying power supply (10), arranged in the mains power region (1), generates a rectified voltage applied to supply terminals (11) from a mains alternating voltage. The rectified voltage at the supply terminals (11) may be supplied to a first motor connection (20), arranged in the mains voltage region (1), depending on a first control signal (MS1). The control further comprises a first control device (30), arranged in the mains voltage region (1), an operating connection (32) and a first control output (31), for providing the first control signal (MS1). An operating device (40), arranged in the low voltage region (2) is connected to the operating connection (32) by means of an electrically insulating coupling (50).

L'invention concerne une commande de meuble à réglage électrique comprenant une zone tension de secteur (1) et une zone basse tension (2) qui sont galvaniquement séparées. Un dispositif d'alimentation redresseur (10), situé dans la zone tension de secteur (1), génère une tension redressée appliquée aux bornes d'alimentation (11) à partir d'une tension alternative de secteur. En fonction d'un premier signal de commande (MS1), la tension redressée appliquée aux bornes d'alimentation (11) peut être cédée à une première borne moteur (20) placée dans la zone tension de secteur (1). La commande comprend également un premier dispositif de commande (30) placé dans la zone tension de secteur (1), une borne d'activation (32) et une première sortie de commande (31) destinée à émettre le premier signal de commande (MS1). Un dispositif de commande (40) placé dans la zone basse tension (2) est raccordé à une borne de commande (21) par un couplage de séparation galvanique (50).
