Power supply 20
This central power supply for DIN rail mounting is suitable for door and video intercom installations. When used in door intercom installations, a maximum of twenty internal audio units (10-505) and two illuminated external audio units can be connected to the power supply. When used in video intercom installations, an additional direct current power supply (10-805-01) is always required for the displays. The power supply has bus connections, a potential-free relay contact for the light circuit (max. 24 Vdc and 1 A) and an alternating current output for the door opener (8 – 12 Vac). The front side of the power supply is provided with a programming button, a status LED (lights up when put into operation) and two potentiometers to adjust the activation time of the door opener and light circuit.
