KBDF

Variable Frequency Digital AC Drive with CSP™

The KBDF Series of Adjustable Frequency Drives consist of fourteen inverter models rated for 1/8 to 5 horsepower motors. These drives are housed in IP 20 enclosures. They are ideal for OEM applications where digital programming and displays are required. All models are available with a built-in CE approved AC Line Class “A” Industrial Standard RFI (EMI) Filter.

Primary Features

  • Horsepower 1/8 to 5 HP, Programmable
  • 115/230/460 VAC - 1ph & 3ph Input 
  • Output 230/460 VAC - 3ph
  • Starting Torque 200%
  • Digital Display with LED Status Indicators Class “A” (CE) RFI Filter (Order “F” suffix for built in filter, e.g. KBDF-24F)
  • IP 20 Enclosure

Benefits

  • 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. (*CSP™ = Common Sense Programming. Parameters are organized into easy-to-understand intuitive groups.)
  • 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 cost.
  • Economical to Use. No need to derate drive for high starting torque applications. Combines Soft Start with Variable Speed. Adjustable Soft Start.
  • 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 Software allows the 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.
  • Local/Remote Operation. When used with process control, the Local/Remote key can be used to switch from process control to manual control if a process fault occurs.
  • Electronic Inrush Current Limit (EICL™) Protection. Eliminates harmful inrush AC line current during power up.
  • Inputs/Outputs. Seven isolated multi-function inputs with sink or source mode control logic, two analog inputs, two multi-function output relays and one analog output.
  • Built-in Potentiometer. Sets motor speed in lieu of keypad.
  • 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).

Drive Options

  • Memory Module. The Memory Module can store up to four programs for cloning and archiving. The drive can also store up to four programs.
  • IODF Input/Output Multi-Function Expansion Module. Adds up to 5 points of additional I/O. 
  • Drive-Link™ Programming Kit. Allows PC programming.
  • Modbus Serial Communication Module. See instruction manual for complete description.
