This product complies with all CE directives pertinent at the time of manufacture. Contact our

Sales Department for Declaration of Conformity. Installation of a CE approved RFI lter is

required. See RFI Filters & Chokes Selection Guide D-321 (Part No. A42027) for selection of lters that

meet the Industrial or Residential Standard. Additional shielded cable and/or AC line cables may be

required along with a signal isolator (SIAC - Part No. 9600).

3 INTRODUCTION

Thank you for purchasing the KBAC Adjustable Frequency Drive. KB Electronics, Inc. is committed to pro-

viding total customer satisfaction by producing quality products that are easy to install and operate. The

KBAC is manufactured with surface mount components incorporating advanced circuitry and technology.

The drives are variable speed controls housed in a rugged NEMA-4X / IP-65 washdown and watertight

die-cast aluminum enclosure. They are designed to operate 208 – 230 and 400/460 Volt 50 & 60 Hz

3-phase AC induction motors from subfractional thru 5HP. The sine wave coded Pulse Width Modulated

(PWM) output operates at a carrier frequency of 16 kHz which provides high motor eciency and low

noise. Adjustable Linear Acceleration and Deceleration are provided, making the drive suitable for

soft-start applications.

Due to its user-friendly design, the KBAC AC drive is easy to install and operate. Tailoring to specic

applications is accomplished with selectable jumpers and trimpots, which eliminate the computer-like

programming required on other drives. However, for most applications no adjustments are necessary.

For more advanced programming, PC based Drive-Link™ software is available.

Main features include adjustable RMS Current Limit and I

t Motor Overload Protection.* In addition,

Adjustable Slip Compensation with Static Auto-Tune and Boost provides high torque and excellent

load regulation over a wide speed range. Power Start™ delivers over 200% motor torque to ensure

start-up of high frictional loads. Electronic Inrush Current Limit (EICL™) eliminates harmful AC line inrush

current. A Run/Fault Relay is provided, which can be used to turn equipment on or o , to signal a

warning if the drive is put into the Stop Mode, or if a fault has occurred. The drive is suitable for machine

or variable torque (HVAC) applications. Also, a jumper is provided for selection of Regenerative or

DC Injection Braking.

Standard front panel features include Diagnostic LEDs for “Power On” and “Drive 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 (MIN, MAX, ACCEL, DECEL, COMP, CL, JOG, BOOST),

customer selectable jumpers (Line Voltage - dual voltage models only), Motor Horsepower, Automatic

Ride-Through / Manual Start, Motor Frequency, Frequency Multiplier, Fixed/Adjustable Boost, Regenera-

tive / Injection Braking, “Run” or “Fault” Output Relay Operation, NO/NC Stop Contact, Constant/Variable

Torque and I

t Overload Selection).

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 – contact

our Sales Department.

*UL approved as an electronic overload protector for motors.
