Optional accessories include: Forward-Stop-Reverse Switch, On/O AC Line Switch, Run-Stop-Jog Switch,
Signal Isolator, Auto/Manual Switch, Class ”A” AC Line Filter, Multi-Speed Board and Liquidtight Fittings.
A connector is provided for easy installation of accessories. Custom software: all models can be factory
programmed for applications which require special timing, PLC functions, and GFCI operation
(Models KBAC-24D, 27D, 29, 29 (1P), 45, 48) – contact our Sales Department.
*UL approved as an electronic overload protector for motors.
3.1 Standard Features
• Industrial Duty Die-Cast Aluminum Case with Hinged Cover – Available in Dark Gray nish or
FDA approved white nish.
• Simple to Operate – Does not require programming. Uses trimpots and jumpers, which are
factory set for most applications.
• Motor HP Selection Jumper (J2) – Allows the drive to be used on a wide range of motors
without recalibration.
• Switching Frequency and GFCI Selection Jumper (J12) – Allows the drive to be operated
at 8 kHz or 12 kHz and on Standard (G1) or Sensitive (G2) GFCIs. (KBAC-217 Series and
KBAC-416 Series only.)
• Diagnostic LEDs – Power on (POWER) and drive status (STATUS).
• Run/Fault Relay Output Contacts – Can be used to turn equipment on or o, to signal a warning
if the drive is put into the Stop Mode, or a fault has occurred.
• Start/Stop Switch – Provides electronic start and stop functions.
• Barrier Terminal Block – Facilitates wiring of motor, AC Line, and Run/Fault Relay Output Contacts.
• Jumper Selection of Drive Output Frequency – Increases the motor speed up to two times the
rated RPM.
• Ride-Through – Provides smooth recovery to the previous set speed during a momentary power
loss (of less than 2 seconds).
• Holding Torque at Zero Speed – Resists motor shaft rotation when the drive is in Stop Mode.
Note: GFCI Operation: Models KBAC-24D, 27D, 29, 29 (1P), 45, 48 require custom software – contact
our Sales Department. The KBAC-217 Series and KBAC-416 Series are jumper selectable (J12) for Stan-
dard (G1) or Sensitive (G2) GFCIs.
3.2 Performance Features
• Power Start™ – Provides more than 200% starting torque which ensures startup of high frictional loads.
• Slip Compensation with Static Auto-Tune and Boost – Provides excellent load regulation over
a wide speed range.
• Speed Range – 60:1
3.3 PROTECTION FEATURES
• Motor Overload (I
2
t) with RMS Current Limit* – Provides motor overload protection which
prevents motor burnout and eliminates nuisance trips.*
• Electronic Inrush Current Limit (EICL™) – Eliminates harmful Inrush AC Line current during startup.
• Short Circuit – Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).
• Regeneration – Eliminates tripping due to high bus voltage caused by rapid deceleration of high
inertial loads.
• Undervoltage and Overvoltage – Shuts down the drive if the AC Line input voltage goes above
or below the operating range.
• MOV Input Transient Suppression – Protects the drive components against damaging voltage
spikes on the AC Line.
• Microcontroller Self Monitoring and Auto Reboot.
