2.5Description of the SBS

Its electronic high-performance components make the SBS highly overload-resistant and thus capable of quickly eliminating load short circuits.

The SBS can be used as the central SBS for parallel operation of up to 8 INVs.

Another outstanding characteristic of the SBS is its communication capability with other systems via integrated interfaces.

The control electronics of the SBS have been designed on the basis of state-of-the-art microcontroller technology. By using parameters in the software, the main unit characteristics are determined.

Figure 3 illustrates the principle of an SBS.

Load

In normal operation, the SBS is not fired, the load is supplied "Online" by the INV or INVs. If the supply of the load is no longer guaranteed by the INVs or the load voltage has dropped below a permitted value due to a load short circuit, the load is switched over to the mains without interruption.

Apart from power cabling, a bus line is required for the SBS for process control purposes between the INV/INVs and the SBS. The bus line has to be terminated at both ends with a resistor.
