Yaskawa Electric Corporation CIMR-VU4A0038FAA AC Variable Frequency Drive

The Yaskawa CIMR-VU4A0038FAA, part of the V1000 series, is a panel-mounted, IP20/NEMA 1 three-phase variable frequency drive designed for general-purpose motor speed and torque control in industrial automation, and is commonly used for replacement or retrofit in high-horsepower drive systems. It uses a 3-phase input of 380–480 VAC and provides adjustable output from 0 to 480 VAC, delivering approximately 38 A (ND) or 31–32 A (HD typical class) with a power rating around 18.5 kW (≈25 HP). The drive supports open-loop vector control and V/f control, is compatible with AC induction and permanent magnet motors, and offers 150% overload capacity for 60 seconds, with an output frequency range from 0 to 400 Hz. Common applications include conveyors, pumps, compressors, HVAC equipment, and material handling systems, where compact VFD control within a panel-mounted enclosure improves energy efficiency and provides stable process control.
