150-F135NCRD Solid State Controller

The 150-F135NCRD Solid State Controller is a smart motor controller (soft starter) from the SMC-Flex Bulletin 150-F series, manufactured . It is designed to provide smooth acceleration and deceleration of three-phase AC motors, helping to reduce inrush current, mechanical stress, and wear on motors and driven equipment.
Rated at 135 A, this controller is ideal for medium-to-large industrial motor applications such as pumps, fans, compressors, conveyors, mixers, and HVAC systems. The 150-F135NCRD features solid-state SCR technology, an open enclosure design for panel mounting, and an internal bypass contactor that minimizes heat and power loss once the motor reaches full speed.
