Saves Time Easy to Install and Simple to Operate. Does not require commissioning. With CSP™ you are up and running in less than 10 minutes.

Motors Last Longer Proprietary CL Software Provides overload protection, prevents motor burnout and eliminates nuisance tripping. UL approved as electronic overload protector for motors.

Energy Saving Uses only the power the application requires. Replacing constant speed with variable speed will significantly reduce energy costs.

Customization for OEM’s When an off the shelf drive does not meet your needs, KB will work with you to provide a custom drive solution, Ready to Use, “Out-of-the-Box.” Customization includes: Pre-calibrating or programming of a stock control, adding a custom label or branding, custom software, PLC functions or designing a new control.

GFCI Compatible Allows equipment to operate with Ground Fault Circuit Interruption circuit breakers or outlets

Additional Features

Sensorless Flux Vector Control: Flux Vector Compensation with Static Auto-Tune provides excellent speed regulation with high torque loads throughout the entire speed range. Auto energy saving at light loads. Smooth motor torque.

Electronic Inrush Current Limit (EICL™) Protection: Eliminates harmful inrush AC line current during power up.

Multi-Function Output Relay: Can be used to turn equipment on or off, to signal a warning if the drive is put into “Stop” mode, or to signal if a fault has occurred.

Jog-Local/Remote: Set the drive to Jog Mode or changes between Local (Keypad) or Remote Operation

Built-in Potentiometer: Quickest way to change motor speed.

Ride-Through: Provides smooth recovery to the previous set speed during a momentary power loss.

Holding Torque at Zero Speed: Resists motor shaft rotation when the drive is in “Stop” mode

Regeneration Protection: Eliminates tripping due to high bus voltage caused by rapid deceleration of high inertial loads.

Undervoltage and Overvoltage Protection: Shuts down the drive if the AC line input voltage goes above or below the operating range.

Short Circuit Protection: Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).
