6SE7041-8EK85-1HA0 is a Siemens PER2 rectifier interface module for infeed/regenerative-feedback supply units in designs H and K. The official assignment is 380-480 V, 3 AC, 50/60 Hz. It is a component of the supply unit, rather than a complete motor converter.
- Component type: Rectifier interface module
- Interface designation: PER2
- Host function: Infeed / regenerative feedback supply unit
- Assigned designs: H and K
Its documented role is the rectifier interface inside the assigned supply unit. At system level, the rectifying bridge feeds the DC link during motoring; the regenerative bridge transfers energy from that link back toward the supply during generating operation. Individual interface signals, connector pinouts and signal levels are not specified in the exact article entry.
The system combines the assigned H/K supply unit, its control electronics and power section with the DC link and downstream inverters. The Siemens system manual identifies CUR control electronics and an optional OCP in this architecture. An OCP is a separate system component.
PER2 and the exact voltage assignment are essential identifiers. Do not assume interchangeability with other PER versions. The voltage range describes the host supply-unit assignment, not a low-voltage signal rating for the PCB. The current manufacturer listing marks this article discontinued; a generic migration note does not identify a drop-in replacement.

Industrial drive systems
For industrial drive systems using the documented infeed/regenerative-feedback architecture, including duty with power flow to the motors and regenerated energy returning through the supply unit. Match the exact host equipment and voltage class before selecting the interface module.
Equipment integration
The system combines the assigned H/K supply unit, its control electronics and power section with the DC link and downstream inverters. The Siemens system manual identifies CUR control electronics and an optional OCP in this architecture. An OCP is a separate system component.
Use the equipment-specific Siemens manual and approved component assignment.
- Match the exact article, host equipment and hardware revision before installation.
- Isolate all supplies, verify the absence of voltage, observe the specified discharge time and grounding requirements.
- Installation and service require qualified personnel and appropriate electrostatic-discharge precautions.
