CFW11M 4kW 690V Marine
WEG Marine CFW11M 4kW 690V Marine is a marine variable-frequency drive. It is normally installed inside an electrical cabinet, machinery-control panel or dedicated drive room close to the motor or distribution system it controls. Its primary purpose is to regulate AC motor speed and torque by controlling the frequency and voltage supplied to the motor. Compared with direct-on-line or fixed-speed motor starters, a VFD adds power electronics, cooling, software parameters and motor-feedback or communication interfaces that require separate attention. The supplied record already contains the available concise model or rating information, so those existing figures are not duplicated here and no additional meaning is inferred from the model code. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
