Voltage feed-in is about increasing the voltage in an electrical circuit. In a sense, this generates the electricity that is then used for lights and technical devices, for example. This voltage feed is necessary because electrical current only flows with electrical voltage. To increase the voltage, for example, the concentration of electrons is increased at one point in the circuit. This then results in a charge equalization in which the free electrons in the network flow to the point with a lower charge concentration.
In the building services, you can use a low glow lamp. Use a voltage supply for the corresponding circuit to increase the luminosity. For special vehicle construction, we use the voltage supply to ensure that the vehicle electrics function properly. BOS (authorities and organizations with security tasks) and broadcasting are dependent on the voltage supply in order to be able to send signals or operate monitors. This is why the power supply is an important part of our system integration.
