Additional voltage output
Type SV/S 30.640.5.1 and SV/S 30.640.3.1 devices have a 30 V DC voltage output without choke. This
can be used in combination with an additional choke to power a main or area line. To do this, the devices
must be installed in accordance with the connection schematic below.
Please note
The voltage output without choke may not be used for other purposes (e.g. for connecting sensors to a
binary input) because in the event of an error on the voltage output (e.g. a short-circuit) the power
supply and therefore the whole KNX line connected to it will fail!
The voltage output without choke ( I
2
) is not electrically isolated from the KNX voltage output (I
1
). It may
only be used to power an additional bus line in combination with a separate choke. It may not, for
example, be used to power IP devices (see SELV guidelines).
