Variable Frequency Drive (VFD) / Frequency Converter · Frequency Converters & Drives
Schneider Marine Altivar 930 Marine 400kW 690V Marine — 400 kW. As a Variable Frequency Drive (VFD) / Frequency Converter, it is normally installed inside an electrical cabinet, machinery-control panel or dedicated drive room close to the motor or distribution system it controls. In that role, its primary purpose is to regulate AC motor speed and torque by controlling supply frequency and voltage. Compared with a fixed-speed starter, a frequency converter adds power electronics, cooling, software parameters and communication interfaces. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
