1HP KB Electronics KBVF-24D VFD IP-20 115/230VAC 1PH Input 9979

Easy to Install and Simple to Operate

Dimensions approx. 4.3" x 4.7" X 5.0" Agency approvals: UL, CE, CSA, C-Tick, RoHS available.

The KBVF AC drive is easy to install and operate and due to the user-friendly design tailoring to specific applications is accomplished with selectable jumpers and trimpots, which eliminate the computerlike 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 I2 t Motor Overload Protection.2 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. Electronic Inrush Current Limit (EICL™) eliminates harmful AC line inrush current.3 The drive is suitable for machine or variable torque (HVAC) applications. With optional Drive-Link™ software, the drive can be programmed for DC Injection Braking. Other features include adjustable trimpots (MIN, MAX, ACC, DEC/B4, COMP CL), customer selectable jumpers (Automatic- Manual Start, Motor Frequency, Frequency Multiplier, Forward/Reverse, and Line Voltage (dual voltage models only)). Diagnostic LEDs are provided for power (PWR) and drive status (ST). A 5 kΩ Main Speed Potentiometer is also included. A Signal Isolator is optional on all models, which can be used for single-ended or bidirectional speed control and accepts voltage or current signal input. Other optional accessories include Class “A” and “B” AC Line Filters, Dynamic Brake Module, Multi-Speed Board, Programming Kit, and Modbus Communication Module. A connector is provided for easy installation of accessories

KBVF Adjustable Frequency Drive provides variable speed control for standard 3-phase and Permanent Split Capacitor (PSC)1 AC induction motors from subfractional thru 1HP. The sine wave coded Pulse Width Modulated (PWM) output operates at a carrier frequency of 16 kHz, which provides high motor efficiency and low noise. Adjustable linear acceleration and deceleration are provided, making the drive suitable for soft-start applications. For AC line and motor wiring, quick-connect terminals are provided.

Notes: 1. Optional software is required for PSC motors — contact our Sales Department. 2. UL approved as an electronic overload protector for motors. 3. Models KBVF-21D, 22D contain ICL in lieu of EICL™. 4. In 50 Hz Mode, the DEC/B Trimpot automatically becomes Adjustable Boost.

Energy Saving
Uses only the power the application requires Energy savings is realized by using variable motor speed vs. constant speed motors.

Economical to Use
No need to de-rate drive for high starting torque applications. Combines Soft Start with Variable Speed Control (Adjustable Soft Start)
