Video power supply
This video power supply for DIN rail mounting is suitable for video intercom installations with one external video unit, one splitter and a maximum of twelve internal video units (only one of which can be active at any one time). If two internal video units are to be active simultaneously, the installation may only contain six internal video units. The installation can be expanded with one external audio unit, three internal audio units and one relay. The power supply has 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.
