3HP KB Electronics KBAC-45 NEMA4X VFD 460VAC 3PH INPUT 9530

KBAC-45 Hybrid AC Digital Drive with Analog Interface. The KBAC-45 is easy to install and operate.

The KBAC-45 Adjustable Frequency Drive is a variable speed control in a NEMA-4X /IP-65 washdown and watertight enclosure. It is designed to operate 380/460 Volt 3-phase AC induction motors through 4.6 Amps RMS. The sine wave coded Pulse Width Modulated (PWM) output operates at a frequency of 16kHz which provides high motor torque, high efficiency and low noise. 

Tailoring to specific applications is accomplished via selectable jumpers and trimpot adjustments, which eliminate the computer-like programming required on other drives. However, for most applications no adjustments are necessary.

Main features include adjustable RMS Current Limit with I2t Motor Overload Protection. In addition, adjustable Slip Compensation provides excellent load regulation over a wide speed range.

Power Start delivers over 200% motor torque to ensure startup of high frictional loads. Electronic Inrush Current Limit (EICL ?) eliminates harmful AC line inrush current and adjustable Linear Acceleration and Deceleration make the drive suitable for soft-start applications.

The Ride Through feature provides a smooth recovery to the previous set speed during a momentary power loss and Regeneration Protection eliminates tripping due to rapid deceleration of high inertial loads.

Standard front panel features include diagnostic LEDs for Power On and Control Status, a Start/Stop Switch and a Main Speed Potentiometer.

Other features include a Barrier Terminal Block to facilitate wiring of the AC line and motor, adjustable trimpots (MAX, MIN, ACCEL, DECEL, COMP, CL, BOOST) and customer selectable jumpers (line voltage, motor horsepower, auto or manual restart modes, motor frequency, frequency multiplier, fixed or adjustable boost. 

Dimensions approx. 9.80" X 7.55" X 7.25".
Agency approvals: UL, CE, CSA, C-Tick.

On/Off AC Line Switch – P/N: 9532, Disconnects the AC line. Mounts on the enclosure cover and is supplied with a switch seal to maintain liquidtight integrity.

Forward-Stop-Reverse Switch – P/N: 9480, Provides motor reversing and stop functions. Mounts on the enclosure cover and is supplied with a switch seal to maintain liquidtight integrity.

Run-Stop-Jog Switch – P/N: 9340, Selects speed setting from either the Main Speed Potentiometer or the JOG Trimpot. Mounts on the enclosure cover and is supplied with a switch seal to maintain liquidtight integrity.

Signal Isolator – P/N: 9600, Provides isolation between a non-isolated signal source and the drive. Mounts on the drive’s PC board with four snap-ins.

Auto/Manual Switch – P/N: 9481, When used with the Signal Isolator, it selects remote process signal or the Main Speed Potentiometer. Mounts on the enclosure cover and is supplied with a switch seal to maintain liquidtight integrity.

AC Line Filter – (Factory Installed) Provides Class A RFI (EMI) suppression.

Liquidtight Fittings - P/N: 9526, Provides a liquid-tight seal for wiring the drive. Kit includes necessary liquid-tight fittings

*Warning! It is highly recommended that the Signal Isolator (Part No. 9600) be installed when using the drive with external control signals.
