Unidrive SP AC Drive
The Unidrive SP series is a family of AC variable frequency drives used to control three-phase induction motors across a wide power range. The drives regulate motor speed and torque by delivering adjustable frequency and voltage output, supporting precise motor control and energy efficiency in industrial systems.
These drives typically operate from a 380-480V three-phase supply at 50 or 60 Hz and provide variable voltage output up to 480V. The series spans compact units for fractional and low-horsepower motors through larger models rated up to 125 HP (75/90 kW), covering a broad range of motor sizes from a single product line.
Applications
Unidrive SP drives are commonly used in industrial automation, material handling, and process control. Typical end equipment includes conveyors, pumps, fans, and paper processing machinery.
Manufacturers
This series includes drives branded by Emerson, Control Techniques, and Leroy-Somer. Model numbers follow the SP prefix, such as SP0402, SP1402, SP2401, SP2403, and SP5402.
