KB Electronics 9536

The KBDA-24D Adjustable Frequency Drive is a variable speed control encased in a rugged NEMA-4X /IP-65 washdown and watertight die-cast aluminum enclosure. It is designed to operate from 115 or 208/230 Volts, 50/60Hz, single phase AC input, and operates 208-230 Volt, 50/60Hz, 3-phase AC induction motors through 3.6 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.

Setting the drive to a particular application is accomplished using the Multi-Function Keypad. To facilitate programming, all similar functions are presented in common groups. For more those who need more advanced programming, PC based Drive-Link_ software is available.

The 4-Digit LED Display gives the user a readout of drive operating parameters and programming functions and displays Output Frequency, Motor RPM, Output Current, Output Voltage, Bus Voltage, Function Codes, and Values, Fault Codes and Custom Units. The LEDs provide indication of the drive’s status and operating mode (Hz, PGM, LCL/REM, STOP, FWD, REV, OL and JOG/REM).

Primary features are adjustable RMS Current Limit with I2t Motor Overload Protection. Flux Vector Compensation with Static Auto-Tune and Boost that gives this drive high torque and excellent load regulation over a wide speed range. Power Start delivers over 200% motor torque to guarantee startup of high frictional loads. Programmable Injection Braking offers the user rapid motor stop. Electronic Inrush Current Limit (EICL_) gets rid of harmful AC line inrush current, which lets the drive to be line switched. A Multi-Function Output Relay is included, which can be used to turn on or off equipment or to signal a warning if the drive is put into certain modes of operation. The drive is suitable for machine or variable torque (HVAC) applications.

Dimensions approx. 9.6_ X 5.5_ X 5.9_.

Agency approvals: UL, CE, CSA, C-Tick, RoHS available.
