KBMA

Hybrid Drive™ - A Digital AC Drive with Analog Interface

The KBMA Series of Adjustable Frequency Drives consist of two inverter models rated for 1/8 to 1 horsepower motors. These drives are housed in NEMA 1 / IP 50 aluminum enclosures. The KBMA-24DF contains a built-in CE approved AC Line Class “A” Industrial Standard RFI (EMI) Filter. Hybrid drives are a digital drive with an analog interface.

Primary Features

  • Horsepower 1/8 to 1 HP, Jumper Selectable
  • 1Ø Input 115/230 VAC, 50/60 Hz
  • 3Ø Output 230 VAC
  • 200% Starting Torque
  • Front Panel Power On/Off Switch Class “A” (CE) RFI Filter (KBMA-24DF)
  • Rugged Aluminum NEMA 1 / IP 50 Enclosure

Benefits

  • Saves Time. Easy to Install and Simple to Operate. Does not require programming or commissioning. 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.
  • Economical to Use. Eliminates secondary enclosure. No holes to drill, no switches to install. 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, we 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, with factory programming, 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. 
  • Electronic Inrush Current Limit (EICL™) Protection. Eliminates harmful inrush AC line current during power up.
  • Run/Fault 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.
  • On/Off AC Line Switch. Disconnects the AC line.
  • 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).
  • Trimpot Adjustments. Min. Speed, Max. Speed, Accel, Decel, Current Limit, Slip Comp.
  • Jumper Selections. AC Line Input Voltage, Horsepower, Auto/Manual Start, 50Hz/60Hz Motor Frequency, 1X/2X Motor RPM, Run/Fault Output Relay.

Drive Options

  • Forward-Stop-Reverse Switch. Provides motor reversing and stop functions.
