SL / SLX Analogue Control

by Sprint Electric

Model SL SLX - Analogue DC Motor Control Up To 330 Amps (145KW/190HP)

Model SL - 2 Quadrant   |   Model SLX - 4 Quadrant


SL 2 Quadrant and SLX 4 Quadrant models are compact, reliable and efficient DC motor controllers.
 
The 4Q models improve your energy efficiency by regenerating energy into the mains supply whilst under braking. The energy invested accelerating the load mass is recovered when braking. No dissipation of energy in wasteful braking resistors.
 
With fully isolated control electronics and a wealth of I/O, the SL/X are easy for you to integrate with other drives and equipment.
 
To allow you greater control of high motor speed applications, the SL/X has a built-in field weakener for extended speed range.
