Delta Electronics VFD022EL43A Variable Frequency Drive

The Delta Electronics VFD022EL43A is a 2.2 kW (3 HP) variable frequency drive designed for 380–480 VAC three-phase systems, delivering precise motor speed control and torque management in general‑purpose automation. It supports V/Hz control and sensorless vector control, offers an output frequency range of 0–600 Hz, and provides 150% overload capability for 60 seconds, making it suitable for pumps, fans, conveyors, HVAC equipment, and light‑duty machinery that require smooth acceleration and reliable speed regulation. Built‑in features include PID control, EMI filter, RFI switch, and a keypad interface, with an IP20 enclosure and mounting on DIN rail or panel, plus RS‑485 (Modbus) communication and optional fieldbus modules for integration with compatible controllers. Cooling can be natural or fan-assisted depending on the model, and it sits in Delta’s VFD‑EL Series as a common replacement option alongside models such as VFD037EL43A and VFD5A5MS43ANSAA.
