Variable Speed Drives by JSB Engineering Co.

Variable Speed Drives incorporate the world's most advanced technology for three-phase AC induction motors. An Innovation was also introduced to simplify applications that require braking torque. A new feature eliminates the need for the dynamic braking resistor in some applications allowing a simpler, more compact and economic solution.
