SEE category on front page for link to all associated data to this product category: MOTOR CONTROLLERS KB ELECTRONICS

The KBMA Series Adjustable Frequency Drives are variable speed controls housed in a NEMA-1/IP-50 enclosure. They are designed to operated 208-230 Volt 50 & 60 Hz 3-phase AC induction motors from 1/8 HP thru 1 HP. The sine wave coded Pulse Width Modulated (PWM) output operated at a carrier frequency of 16 kHz, which provides high motor efficiency and low noise. Adjustable Linear Acceleration and Deceleration make the drive suitable for soft-start applications. The Motor Horsepower Selection Jumper allows the drive to be used on a wide range of motor horsepower ( 1/8, 1/4, 1/2, 3/4, 1HP) without recalibration or programming.

Its user-friendly design makes the KBMA easy to install and operate. Setting the rive to specific applications is accomplished with selectable jumpers and trimpots, which eliminates 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 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 startup of high frictional loads. Electric Inrush Current Limit (EICL) eliminates harmful AV line equipment or to signal a warning if the drive is put into the Stop Mode or a fault has occurred.

Standard front panel features include an On/Off AC Line Switch, a Pilot Light for power on, and a Main Speed Potentiometer. Other features include PC board mounted diagnostic LED's (Power On (ON), Drive Status (ST) and Overload (OL), Barrier Terminal Blocks to facilitate wiring (AC line, motor, ground (earth), and Run/Fault Relay Output Contacts), adjustable trimpots (MIN, MAX, ACCEL, DECEL, COMP, CL), customer selectable jumpers (AC Line Input Voltage Selection, Motor Horsepower, Automatic or Manual Start and Reset, Motor Frequency, Frequency Multiplier, "Run" or "Fault" Output Relay Operation).
