Delta Electronics VFD022M21A Variable Frequency Drive

The Delta Electronics VFD022M21A AC Drive is a compact 2.2 kW (3 HP) variable frequency drive designed to regulate speed and torque of three‑phase motors powered from a single‑phase 220–230 V supply in PLC‑controlled systems. It delivers 0–230 V AC three‑phase output and 0–400 Hz, with V/F control and sensorless vector control for smooth acceleration, reliable startup, and adjustable speed. With a 150% overload rating for 60 seconds, forced‑air cooling, and panel mounting, it suits industrial and light‑duty automation environments such as water pumps, ventilation equipment, conveyors, woodworking machines, and packaging lines, helping reduce energy consumption and match motor speed to process requirements. Protection features include overcurrent, overvoltage, undervoltage, overload, and overheating, while RS‑485 (Modbus) provides easy integration into PLC networks. Operating temperature range is −10°C to 50°C, and the drive is designed for panel‑mounted installation in control panels and machine enclosures. Common replacements include Delta VFD022EL21A AC Drive, VFD022B21A AC Drive, and Schneider ATV12HU22M2 AC Drive, reflecting its role in compact, replaceable drives for retrofit projects and new builds alike.
