Product Overview

6SE7024‑1EB85‑0AA0 is a compact regenerative rectifier unit for small‑to‑medium‑power SIMOVERT MASTERDRIVES multi‑drive configurations. It eliminates brake‑resistor heat losses by feeding regenerative motor braking energy back to the utility grid. Used for material‑handling, crane, test‑bench and production‑machinery multi‑drive systems. Discontinued Siemens drive spare hardware supplied as refurbished and surplus tested units for legacy‑drive‑system maintenance.

Application Notes

‑ Respect cabinet cooling clearance requirements; observe power‑derating rules for high ambient temperature. ‑ Execute full DC‑bus discharge before any internal service work. ‑ Verify firmware compatibility with connected inverter units. ‑ Typical deployment: factory‑automation multi‑drive regenerative power‑supply spare‑part stocking.
