VFD9A0MS43ANSAA 3.7kW Compact Vector Control Drive 460V | Delta

The Original New Delta VFD9A0MS43ANSAA is a 3.7 kW (5 HP) compact vector control drive from the Delta MS300 series, designed for precise motor speed and torque control in industrial automation systems. Accepting 460 V three-phase input with 9.0 A heavy-duty and 10.5 A normal-duty output current, this drive delivers reliable performance for machine tools, textile machinery, woodworking equipment, and material handling applications. The MS300 series features sensorless vector control (SVC) for both induction motors (IM) and permanent magnet motors (PM), a built-in PLC with simple programming capability, and an integrated STO (Safe Torque Off) safety mechanism. The compact Frame C1 design with IP20 protection enables space-efficient panel mounting, while built-in USB and RS-485 (Modbus) communication support easy configuration and system integration.
