SEW-EURODRIVE HD003 Output Choke (813 558 4)

The SEW-EURODRIVE HD003 (part number 813 558 4) is a ring-core output choke that reduces radiated interference from unshielded motor cables on SEW frequency inverters.

The three motor phases (not PE) are routed together through the choke, wrapped 5 times, or 4 times with 2 chokes in series and 3 times with 3 chokes in series for large cable sizes. A shielded cable's shield is not routed through it. The HD003 is sized for cable cross sections of 16 mm2 (AWG6) and above, has a maximum power loss of 30 W and weighs 1.1 kg. Mount it close to the inverter, outside the inverter's minimum clearance.
