SB19 Series Semiconductor AC Frequency Converters for Efficient Motor Control

Semiconductor AC frequency converters of SB19 series are designed to supply three-phase AC induction motors of various mechanisms and machines, where it is required to change the speed smoothly in a wide range. They are used for power supply and speed regulation of squirrel cage motors in various production mechanisms: fans, smoke pumps, pumps, feeders, mills, drives of lifting and transporting machines and conveyors, in closed systems of automatic regulation of various technological parameters, speed stabilisation systems.
