SEW-EURODRIVE MLU11A 8225842

SEW EURODRIVE MLU11A 24V Power Supply Unit Description The SEW EURODRIVE MLU11A is a dedicated 24V power supply module designed for SEW’s range of frequency inverters, notably the MOVITRAC B series. This unit ensures that the control electronics of the inverter remain powered independently of the main power supply. This feature is essential for system maintenance, diagnostics, and preserving fieldbus communication during a main power shutdown. It’s a vital component for applications requiring high uptime and easy serviceability. Specifications Manufacturer: SEW EURODRIVE Type: MLU11A Part Number: 8225842 Function: 24V DC Auxiliary Power Supply Output Voltage: 24V DC Compatibility: Designed for SEW MOVITRAC B series inverters Label Info SEW EURODRIVE 24V-Versorgung MLU11A Sach.Nr. 8225842 Application This power supply unit is typically used in industrial automation systems where SEW drives are employed. It is particularly useful in complex machinery where control logic needs to be maintained for quick restarts, or where remote diagnostics via fieldbus are required even when the main motor power is off for safety. Country of Origin This product is manufactured by SEW EURODRIVE in Germany. CO2 Impact Choosing this pre-owned component saves an estimated 12.0 kg of CO2 compared to manufacturing a new one. This is equivalent to the emissions from charging over 1400 smartphones. Availability This item is an obsolete part but is available from our stock.

The MLU11A provides a continuous 24V DC supply to the control electronics of a compatible SEW inverter (like MOVITRAC B). This allows the control unit, operator panels, and fieldbus communications to remain active even when the main 3-phase power to the inverter is turned off. Can I use the MLU11A with the newer MOVI-C series inverters? No, the MLU11A is specifically designed for the form factor and internal connections of the older MOVITRAC B series. Newer series like MOVI-C require different, specifically designed 24V supply options or an external DIN-rail power supply. Where does the MLU11A get its input power from? The MLU11A is an internal option module that draws power directly from the inverter’s internal DC link. It does not require a separate external AC or DC input connection. profideals is not an authorized distributor, reseller, or representative of the products featured on this website.
