Thank you for purchasing the KBWA Series Hybrid Drive. KB Electronics, Inc. is
committed to providing total customer satisfaction by providing quality products that
are easy to install and operate.
The KBWA Series are Digital Drives with Analog Interface. Model KBWA-23D is
housed in a NEMA 1 / IP20 vented enclosure. Models KBWA-22D, 21D, 2P6D, 2P3D
are housed in a NEMA 1 / IP50 non vented enclosure. They are designed to operate
subfractional thru 1/2 HP 208 – 230 Volt 50 & 60 Hz 3-phase AC and PSC induction
motors.
1 Flux Vector Control provides high torque, low noise, and excellent load
regulation over a wide speed range. Adjustable Linear Acceleration and Deceleration
make the drive suitable for soft-start applications.
Due to its user-friendly design, the drive is easy to install and operate. Tailoring to
specific 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.
Main Features: Adjustable RMS Current Limit and I
2 t Motor Overload Protection. 2
Flux Vector Control with Static Auto-Tune 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. Electronic Inrush Current Limit (EICL™)
eliminates harmful AC line inrush current. The drive is suitable for machine or variable
torque (HVAC) applications. A terminal block is provided to facilitate AC line input,
motor, and ground connections. Adjustable trimpots (MIN, MAX, ACC, DEC, COMP,
CL). Customer selectable jumpers (Automatic/Manual Start, Motor Frequency,
Frequency Multiplier, Forward/Reverse, and Line Voltage). PC board mounted
diagnostic LEDs provide indication of power on (PWR) and drive status (ST). The
drive includes a factory installed Main Speed Potentiometer and an illuminated On/Off
AC Line Switch. The drive also has provision for a Forward-Stop-Reverse Switch
(supplied) for reversing applications.
Options: Custom software for OEM applications. This drive can also be factory
programed to operate with GFCIs – contact our Sales Department.
Notes: 1. Operation with PSC motors requires factory programming – contact our
