Toshiba VFS9-4075PL-WN Transistor Inverter Drive

The Toshiba VFS9-4075PL-WN Transistor Inverter is a 7.5 kW (10 HP) variable-frequency drive for three-phase AC induction motors, delivering precise speed control, soft starting, and energy-efficient operation in industrial drives. Maintenance teams, OEMs, and system integrators use this inverter for replacement of failed motor drives, preventive maintenance, machine upgrades, and restoration of Toshiba TOSVERT VF-S9 drive systems, with wide deployment in conveyors, pumps, fans, compressors, HVAC equipment, packaging machinery, and material handling lines. Key specifications include input of 3-Phase 380–500 VAC at 50/60 Hz, approximately 13.0 kVA rated capacity and 17 A rated output current, and an output range of 0–500 VAC at 0.5–400 Hz. The unit implements Sensorless Vector Control and V/f control, and includes built-in PID control, Auto Restart, Electronic Thermal Protection, Multi-Speed Operation, and Dynamic Braking Support. Communication is via RS-485; protection is IP20 with forced-air cooling and panel-mount installation. It serves industrial motor speed control and factory automation across manufacturing plants, HVAC systems, water and wastewater facilities, food and beverage processing equipment, textile machinery, printing presses, and conveyor-driven equipment requiring reliable torque and speed regulation.
