Abstract (en)
[origin: EP1437463A2] A self-locking N-channel MOSFET (T1) in a source circuit has its source earthed for feeding a current to a door opener (TO) that fits between the MOSFET's drain connection and the door opener's positive voltage supply (UBT). A diode (D3) is coupled parallel to the door opener with its anode on the MOSFET's drain connection and its cathode on the door opener's positive voltage supply. Independent claims are also included for the following: (a) A power supply unit for a door opener operated by direct current; (b) and for a method for triggering a door opener operated by direct current.
