KBWK
Digital AC Drive with CSP™* for 3-Phase AC Induction Motors
The KBWK Digital Adjustable Frequency Drive is rated for 1/8 to 1/2 horsepower motors. This drive is housed in a NEMA 1 / IP 20 enclosure and features a digital display with LED status indicators.
Primary Features
- Horsepower 1/8 to 1/2 HP (Lower horsepower models available (KBWK-21D, 2P3D, 2P6D)
- One Model for 115 and 230 VAC -1ph Input • Output 230 VAC - 3ph • Starting Torque 200% • Ultra Bright Digital Display with LED Status Indicators
- Front Panel Power On/Off Switch
- GFCI Compatible. Contains proprietary software which prevents GFCI circuit breakers and outlets from tripping
- IP 20 Enclosure
Benefits
- Saves Time. Easy to Install and Simple to Operate. Does not require commissioning. With CSP™ you are up and running in less than 10 minutes. (CSP™ = Common Sense Programming. Parameters are organized into easy-to-understand intuitive groups)
- Motors Last Longer. Proprietary CL Software. Provides overload protection, prevents motor burnout and eliminates nuisance tripping. UL approved as electronic overload protector for motors.
- Energy Saving. Uses only the power the application requires. Replacing constant speed with variable speed will significantly reduce energy costs.
- Customization for OEM’s. When an off the shelf drive does not meet your needs, KB will work with you to provide a custom drive solution, Ready to Use, “Out-of-the-Box.” Customization includes: Pre-calibrating or programming of a stock control, adding a custom label or branding, custom software, PLC functions or designing a new control.
Additional Features
- Sensorless Flux Vector Control. Flux Vector Compensation with Static Auto-Tune provides excellent speed regulation with high torque loads throughout the entire speed range. Auto energy saving at light loads. Smooth motor torque.
- Electronic Inrush Current Limit (EICL™) Protection. Eliminates harmful inrush AC line current during power up.
- Jog. Provides a fixed preset speed.
- Built-in Potentiometer. Sets motor speed in lieu of keypad.
- Ride-Through. Provides smooth recovery to the previous set speed during a momentary power loss.
- Holding Torque at Zero Speed. Resists motor shaft rotation when the drive is in “Stop” mode.
- Regeneration Protection. Eliminates tripping due to high bus voltage caused by rapid deceleration of high inertial loads.
- Undervoltage and Overvoltage Protection. Shuts down the drive if the AC line input voltage goes above or below the operating range.
- Short Circuit Protection. Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).
