Toshiba VFS15-4075PL-W Transistor Inverter Module

The Toshiba VFS15-4075PL-W Transistor Inverter is a 7.5 kW (10 HP) variable frequency drive for three-phase induction motors, enabling adjustable speed, smooth soft starting, and reliable control in industrial automation. It accepts 3-phase input of 380–500 VAC at 50/60 Hz and provides three-phase output of 0–500 VAC with a rated output current of 17.0 A and a 13.0 kVA rating, supporting motor feeds up to 7.5 kW. It uses Sensorless Vector Control and V/f control for precise speed regulation across 0.1–500 Hz, and can handle 150% overload for 60 seconds or 200% for 0.5 seconds to accommodate brief peak demands. Communication is via RS-485/RS-422 (Modbus RTU), making it suitable for integration with PLCs and HMI systems. Built-in features include PID control, dynamic braking circuit, EMC filter, multi-speed operation, auto restart, and electronic thermal protection, all housed in an IP20 enclosure with forced-air cooling. The unit supports wall or panel mounting and presents a LED digital display for quick parameter readouts. Its rugged design and comprehensive protection make it a common replacement and upgrade option for conveyors, pumps, fans, compressors, HVAC equipment, packaging machinery, material handling systems, and other OEM production lines requiring reliable 3-phase motor drive control.
