KBWA
Hybrid Drive™: A Digital Drive with Analog Interface
The KBWA Series of Adjustable Frequency Drives consist of two inverter models rated for 1/8 to 1/2 horsepower motors. These drives are housed in NEMA 1 enclosures (Model KBWA-22D: IP 50, model KBWA-23D: IP 20). Both models contain an On/Off AC Line Switch and a Main Speed Potentiometer. Hybrid drives are a digital drive with an analog interface.
Primary Features
- Horsepower 1/8 to 1/2 HP (Lower horsepower models available KBWA-21D, 2P3D, 2P6D)
- Input 115 and 230 VAC - 1ph
- Output 230 VAC - 3ph
- Starting Torque 200%
- Front Panel Power On/Off Switch
- GFCI Compatible: With factory programming, allows the equipment to operate with Ground Fault Circuit Interruption circuit breakers or outlets
- IP 20 Enclosure
Benefits
- Saves Time. Easy to Install and Simple to Operate. Does not require programming or commissioning. Up and running in less than 10 minutes.
- 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, we 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.
- 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).
- Trimpot Adjustments. Min. Speed, Max. Speed, Accel, Decel, Current Limit, Slip Comp.
- Jumper Selections. AC Line Input Voltage, 50Hz/60Hz, Motor Frequency, 1X/2X Motor RPM, Automatic/Manual Start Mode, Forward/Reverse Speed Select.
Drive Options
Supplied Forward-Stop-Reverse Switch. Provides motor reversing and stop functions.
