Power supply for a 2-wire system in a 6 DIN module housing. Power supply 110 – 240 Vac at 50 – 60 Hz. The output provides two power supplies at very low safety voltage (one to the 3 TK BUS, IU BUS, and SCS terminals, one to the 1 - 2 terminal), which can be used alternately but not simultaneously. It is suitable for audio, video, or mixed audio-video systems. The video adapter is integrated into the device (Article 346830 must not be used). Therefore, it is possible to avoid using the A/V node or the multi-channel matrix, provided that no more than three connections (maximum 2 IU + 1 TK risers or 1 IU + maximum 2 TK risers) are exceeded from the terminals. It can also be used as an additional power supply (1 - 2 output) for the local power supply of the preset internal units or input panels (in this case, the use of other outputs is not possible). The device is electronically protected against overload and short circuit. It is a SELV double protection safety device. Installation must be carried out in accordance with applicable regulations. The device must not be configured. Warning: The IU BUS, TK BUS, and SCS outputs can be used simultaneously, provided that the maximum total current of 1.2 A is not exceeded. Disconnect the power supply after overload or short circuit for 5 minutes.
