S Series Industrial Purpose Micro Drives
Ratings from 240 - 480V up to 15HP
Industrial Micro Drives
Benshaw S Series Variable Frequency Micro Drives provide a rugged, compact, economical chassis drive solution for low horsepower applications. Each drive in the series offers quick setup and preconfigured settings for common variable frequency drive applications, and a flexible, programmable I/O for more demanding applications or complex control strategies. S Series drives are dual rated for both variable torque (120%) and constant torque (150%).

Highlights
Robust Design
Construction of the air flow design minimizes exposure of critical components (IGBT, PCB, etc.) to outside contaminants
Bult-in EMC Filter
Embedded C3 EM filter to meet EN618000-3 standards and provide noise reduction
V/F Acceleration and Deceleration Function
Auto torque boost (ATB) enhancing acceleration performance in V/F modeFlux braking enhancing deceleration performance in V/F mode
Sensorless Vector Control
Performs enhanced high torque at low speed with sensorless vector control
