Product basics
The K4000 is a high frequency inverter designed for application up to 4000 Hz. The
K4000 family consists of several models with output ratings from 5 to 120 kVA. the
selective harmonic suppression -SHS - developed by DANAHER-MOTION, is aimed
at reducing motor losses and winding stresses without output filter.
• The KEYPAD PC560 control unit can be integrated on the front panel or supplied
as a separate remote control unit.
• The drive is equipped with a RS232 / 422 serial link. A communication protocol in
terminal mode for PC is available on request
• The UL certification of the KT4000 is in process
• The 19” rack version KL4000 will not be UL certified
