    Subject of the invention
  • The subject of the present invention is a feeding electronic circuit applicable to electric door openers permitting to activate a magnet for driving a cam or a blocking / unblocking element for the catch of a door opener.
  • This electronic circuit has characteristics aimed at permitting the magnet activated by the electronic circuit, to be capable to actuate any horizontal or vertical cam, or blocking / unblocking element of the door opener, having a preload of up to 30 Kp.
    • State of the art
  • To carry out opening of electric door openers these latter incorporate internally a driving electric device connected to an external connecting strip, said driving electric device consisting in an actuator or magnet that when activated it displaces the retention lever towards a non operating position in which it releases the blocking lever, permitting therefore the rotation of the swivelling catch and the opening of the door.
  • These door openers are designed to be fed a particular electric current, either, alternating or direct, with a given voltage, which means a drawback, both for the manufacturers who must have different models available and also for the installers, who must have for each repair or installation operation the suitable door opener to be fed with the electric current available in each case.
