AC Drives

Lenze AC Tech's most technically advanced compact inverter drive. The performance and flexibility make the SMVector an attractive solution for a broad range of AC Motor applications.

The compact packaging and comprehensive functionality make the SCM and SCL an ideal drive solution for use on equipment requiring variable speed, soft starting or reversing operation.

Cutler-Hammer ® NFX9000 adjustable frequency AC Drives from Eaton’s electrical business are designed to provide adjustable speed control of three-phase motors. 

The KBAC Adjustable Frequency Drive is a variable speed control housed in a rugged die cast NEMA-4X / IP-65 washdown and watertight enclosure. They are designed to operate 208-230 and 460 Volt 3-phase AC induction motors through 5 HP.

The KBIC® controls PM, Shunt and AC/DC motors over a range of 1/100 - 3 HP with only a few models. All models can be used on a wide range of motor horsepower by inserting KB’s exclusive Plug-In Horsepower Resistor®.

The KBMM™ full-wave DC motor control is the ultimate in reliability and performance. Contains Direct-Fed™ current limit that helps protect the SCR power bridge against direct shorts and prevents demagnetization of PM motors.

The KBCC™ chassis controls utilize the KBMM™ speed control to provide a low-cost, reliable SCR drive. They include all the features of the KBMM™ plus the Auxiliary Heat Sink and Barrier Terminal Block with AC line and armature fuses.

The KBRG™ is a full-wave regenerative control, capable of operating a DC motor (Permanent Magnet or Shunt) in a bidirectional mode. It provides 4-quadrant operation which allows forward and reverse torque in both speed directions.

The KBWM control is a compact version of the Multi Drive™ (KBMD). The control is packaged in an all-metal NEMA-1 enclosure. This unidirectional SCR drive utilizes the KBMM speed control module, which prevents motor failure due to demagnetization.

The Model KBMD-240D, also called Multi-Drive™, is a packaged SCR drive in a NEMA-1 enclosure. It utilizes the KBMM™ speed control for its electronics. The Multi-Drive™ is rugged and compact in size.

The KBPC Series NEMA-4X (IP-65) SCR DC Motor Speed and Torque Control is designed for applications requiring washdown and watertight integrity. Its housing is ruggedly constructed of die cast aluminum which is protected with an acrylic coating. Exclusive Short Circuit and Timed Current Limit (TCL) circuitry prevents motor burnout and demagnetization of PM motors.

The KBPW-240D is a Pulse-Width Modulated (PWM) control in a NEMA-4X  / IP-65 washdown and watertight enclosure designed to operate Permanent Magnet and Shunt Wound motors through 7.5 Amps DC. This provides high motor efficiency, whisper quiet operation along with less motor heating.

The KBRC-240D is a Full-Wave Regenerative Drive in a NEMA-4X / IP-65 washdown and watertight enclosure. It is designed to operate 90 and 180 Volt Permanent Magnet and Shunt Wound DC motors in a bidirectional mode. It provides 4-quadrant operation, which allows forward and reverse torque in both speed directions.
