Delta VFD004L21A 0.4kW 0.5HP VFD-L Inverter Drive Single Phase 230V

The DELTA VFD-L VFD004L21A is a compact AC variable frequency drive that is specifically engineered to provide precise speed control for small three-phase induction motors with a power output of up to 0.4 kW (0.5 HP). This inverter is the optimal choice for OEMs and panel builders who need a dependable, cost-effective solution for light-duty industrial and commercial applications, including tiny conveyors, woodworking machines, and auxiliary drives.

The VFD004L21A is capable of delivering seamless acceleration, deceleration, and torque control while simultaneously reducing energy consumption and mechanical stress. It operates on a 200–240 V AC class with a three-phase motor output and single-phase input. Stable operation in severe industrial environments is enabled by the integration of an EMI filter and essential protections.
