Allen-Bradley 20D0075 Variable Frequency Drive

The Allen-Bradley 20D0075 AC Drive is a variable frequency drive (VFD) designed to control the speed and torque of three-phase AC motors in industrial automation, accepting 1‑phase or 3‑phase 200–240 VAC input and delivering 3‑phase output up to 1 HP (0.75 kW). It provides a 0–300 Hz output range with V/Hz control, adjustable frequency resolution, programmable acceleration and deceleration, and an industrial-duty overload rating for reliable soft-start and precise speed regulation in pumps, fans, conveyors, HVAC units, and packaging equipment. The drive is panel-mount with forced-air cooling and includes an integrated keypad and status display, plus serial or network communication options for configuration in control panels; protection features cover overcurrent, overvoltage, undervoltage, overtemperature, and short circuit. Common replacements include Allen-Bradley PowerFlex 70 20AD0075 Series VFD, Schneider Electric Altivar ATV320, and Siemens SINAMICS G120C.
