System role

This section explains what the product does and where it acts in the surrounding system.

Function: Rectifies three-phase input power in a SINAMICS drive power section.
System position: Sits in the rectifier power stage upstream of a SINAMICS DC link.
Upstream / inputs: Receives the documented upstream power, control, or operator input for this system path.
Downstream / outputs: Delivers the documented output or interface signal to the downstream system element.
Limitations: Unknown: installation fit, wiring, firmware, physical condition, and current commercial availability require separate confirmation.
