The DELTA VFD022S43D is a high-performance variable frequency drive (VFD) from Delta’s VFD-S series, designed for 3HP (2.2kW) 3-phase motors operating on 380-480V 50/60Hz power. It offers precise speed control with a 1-400Hz output range, adjustable V/f curves, and built-in PID functionality for automation systems. Certified to UL, CE, and GB standards, this drive includes Modbus communication for integration with industrial networks, plus robust features like auto torque boost, slip compensation, and power-loss restart. Compact and reliable, the VFD022S43D is ideal for applications like textile machinery, packaging equipment, and conveyor systems, though it is now discontinued by the manufacturer.
