Medium-voltage adjustable frequency drive
Eaton’s SC9000 EP medium-voltage adjustable frequency drive improves energy efficiency, reliability, and safety in harsh industrial environments. The powerpole inverter with heat pipe technology provides power density in a compact footprint while enabling the SC9000 EP drive to withstand harsh environmental conditions. By incorporating a three-level neutral 5 point clamped (NPC) inverter topology, the drive reduces the number of power switching devices in the inverter and reducing the overall components needed. The SC9000 EP drives are engineered to enhance personnel safety during maintenance by incorporating a grounding stick to support safe access to the dc bus and mechanical system interlocks.
