Device for providing power supply voltage to building installation bus of building automation system, has source terminal to connect voltage source with voltage supply device to receive source voltage of voltage source

摘要

The device (20) has a bus terminal (28) to connect the voltage supply device with a building installation bus (12). A source terminal (24) is provided to connect a voltage source (22) with the voltage supply device. The source voltage of the voltage source is received over the source terminal. The power supply voltage is produced at the bus terminal based on the received source voltage. A solar panel used as the voltage source is attached with the source terminal. Independent claims are included for the following: (1) a method for operating voltage supply device; and (2) the building automation system.
