With a 0.75 kW / 1 HP motor capacity, 200–240 VAC single-phase input and 4.2 A rated output current, it provides a practical solution for machinery where controlled acceleration, deceleration and variable motor speed are required.

Built as part of Delta's VFD-EL-W Series, the VFD007EL21W combines essential motor-control functions with a compact design. The drive supports V/f and vector control, 0.1–400 Hz output frequency, PID control and RS-485 communication with Modbus support. Its IP20 construction and natural cooling make it suitable for installation inside appropriate industrial control panels.

The VFD007EL21W can be applied to a variety of equipment where dependable motor speed regulation is needed, including conveyors, fans, pumps, packaging machinery, small production machines and general-purpose motor-driven equipment. Its compact size and single-phase input make it especially useful where three-phase AC motor control is required but only a single-phase supply is available. Delta's documentation also identifies dedicated environmental requirements for this model, including a recommended operating temperature range of -10°C to 50°C, with special consideration above 40°C.
