Product details

It handles a maximum continuous current of 1230 A, with a rated current of 1107 A. The 0.000024 H inductance limits di/dt and smooths commutation notches on the converter input, reducing harmonic stress on the upstream supply and the DC link.

The 1107 A rated current (ILN) is the design point for the 2% voltage drop; sizing the converter line above this current will push the drop higher and may reduce available motor voltage. The 830 V operating voltage covers 690 V class drives with margin, but not 1000 V systems. The flat-type main circuit terminals accept busbar or large cable lugs, not spring-cage or screw-clamp connectors.
