KB Electronics 9987

The KBAC-24D Adjustable Frequency Drive is a type of variable speed control in a NEMA-4X /IP-65 washdown complete with watertight casing. It is made to operate 208-230 Volt 3-phase AC induction motors through 3.6 Amps RMS. The sine wave coded Pulse Width Modulated (PWM) output functions at a frequency of 16kHz, giving this drive significant motor torque, a high level of efficiency and helps diminish noise.Due to its simple interface, the KBAC-24D is easy to install and easy to operate. Finding the setting for your particular applications is easy to do using adjustable jumpers and trimpot adjustments, which eliminate the computer-like programming required on other drives. However, for almost all applications no adjustments will be needed.The main benefits include adjustable RMS Current Limit with I2t Motor Overload Protection. Also, adjustable Slip Compensation provides very high load regulation over a significant speed range. Power Start provides greater than 200% motor torque to guarantee startup of high frictional loads. Electronic Inrush Current Limit (EICL _) gets rid of harmful AC line inrush current and adjustable Linear Acceleration and Deceleration make the drive a good fit for soft-start applications. The Ride Through option gives the user an easy recovery to the previous set speed during a sudden power loss and Regeneration Protection discards tripping due to quick deceleration of high inertial loads.For this drive, the standard front panel features include diagnostic LEDs for Power On and Control Status, a Start/Stop Switch and a Main Speed Potentiometer. Other options 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).Optional features are: a Forward-Stop-Reverse Switch, Auto/Manual Switch, Power On/Off Switch, Signal Isolator /Run Relay and a Multi Speed Board. Quick-connect terminals are provided for easy installation of all accessories.View ManualView Data Sheet
