It accepts 220V single or three-phase input and outputs a stable three-phase voltage with adjustable frequency from 0 to 400Hz. Featuring advanced vector control, comprehensive protection mechanisms, and noise reduction technology, this VFD ensures reliable, efficient, and quiet operation for professional industrial applications. ## Description Product description IMPORTANT NOTE This drive only works with 3-phase asynchronous motors. Please make sure your motor is a 3-phase asynchronous motor before purchasing. To protect the VFD, be sure to press the red button "Stop" and turn off the power when you stop using it.When the VFD is working, the inside of the heat sink may reach about 176℉ (80℃), please pay attention to the protection measures! The motor ( or other loads ) and the VFD can only be connected by wire without anything between （eg. No switch can be installed between them).If you want to use the switch to control the load, please refer to the following method to connect the terminals. The two ends of the switch are connected to FWD and GND, turn on the switch, the motor is turning positive, turn off the switch, the motor stops working.The two ends of the switch are connected to REV and GND, turn on the switch, the motor reverses, turn off the switch the motor stops working.Select the function you want to achieve to connect the switch. Panel Operation Instructions Advanced Features Independent control panel and detachable for remote control. Parameters can be set to achieve the braking function. Support 5V or 10V PWM control frequency. Single/Three-phase: We offer single-phase 220V and three-phase 220V inputs. When used for single-phase, the other phase can be used as a spare line. Use the parameter setting to achieve the effect similar to the external resistor. A high capacitance with low output torque 0.5HZ-150% and low speed operation. Superior anti-interference performance. Simple operating guide（motor） Connecting load devices (eg.motor) If the input power is single-phase 220v, then connect to R and T. S is empty and does not need to be connected； If the input power is three phase 220v then connect to R, S and T；For 3KW power models, only L and N need to be connected and the other wire is empty. The three wires of the motor are connected to U,V,W, Motor junction box needs to be changed to Δ wiring method (You can see the motor nameplate is generally marked delta for three-phase 220v, Y for three-phase 380v, if you do not understand the motor name plate to take photos to us). Set The Initial Test Parameters pn32=6, pn02=rated frequency of the motor, pn03=2, pn04=1；pn10=rated frequency of the motor；pn12=rated frequency of the motor After setting as above, press the RUN button to start and STOP button to stop, FWD/REV button to switch forward and reverse, and the panel up / down buttons to adjust the speed. Cooling Fan With fan cooling and efficient heat dissipation capability, it makes sure the internal temperature of VFD is suitable for long and consistent operation. Excellent Material The drive board is cleaned and spray painted. A high torque, high precision, fully adjustable speed drive with unique control method enables it to adapt to harsh grid, temperature, humidity and dust interference capability.(Protection class IP30) Widely Applications Used in mechanical winders, mixers, extruders, slitters, winders, compressors, ventilators, pumps, grinders, elevators, and other speed control machines. Review: excellent product - Excellent, it works perfectly. I used it for my cylinder head grinding machine and it worked without any problems. Review: Works great and support was very helpful! - I use this to add a 2nd and 3rd phase to be able to run my 3 phase air compressor. I reached out to their support before I bought it and they were very helpful. They wanted a picture of the data plate from the motor and had their engineers review to recommend which size I should get. I mentioned to them that it was for an air compressor and they even provided instructions to set it up to work with my pressure switch! I would highly recommend this VFD if you only have single phase and want to run a 3 phase motor. (Ignore my wiring. I tried another VFD first and ran 10/3 with a 30A breaker. When I switched to this one I ran 8/3 (you can use 8/2 though) with a 40A breaker. I just haven't tidied it up yet. ) ## Features - 【Attention】External resistance is not supported, you can adjust the parameters to achieve the function of external resistor. If your motor is heavy duty, please choose a higher power VFD. △ (Delta) connection is recommended for this product. If you have complex needs, please do contact customer service before use to get accurate advice. Please attach pictures of the load equipment parameters ( e.g. nameplate of the motor) - 【Product Parameters】Power: 3KW, input voltage: AC 220V(180-250V),output voltage 220V;input current 14A, output current 20A; input frequency 40-60HZ, output frequency: 0-400HZ; input phase: single-phase or three-phase, output phase: three-phase. - 【Intuitive Display and Button】The display and keys of the product can let users get started quickly. After the panel is disassembled, it can be connected to the corresponding interface to achieve remote control. - 【Various Protection】The product has overload protection, fuse protection, overvoltage protection (DC voltage > 400), or low voltage protection (DC voltage < 200), restart protection, stall protection, short circuit protection, and overheat protection. - 【Good Noise Control】The product has the advantages of low noise and low electromagnetic interference, which are achieved by the excellent PMW control technology and component compatibility design. There is enough space for cooling between each component, and the product casing is designed with multiple holes, the above features can make this VFD have a longer service life. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09C5NV14D | | Antenna Location | CNC Router, Spindle Motor, Compressor | | Best Sellers Rank | #45,130 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Motor Drives | | Brand | HKS | | Built-In Media | VFD*1 | | Customer Reviews | 4.0 out of 5 stars 159 Reviews | | Display Type | physical display | | Electrical Output Waveform | Pure Sine Wave | | Energy Specifications Met | UL, CE | | Frequency | 400 Hz | | Included Components | VFD*1 | | Input Voltage | 220 Volts | | Inverter Capacity Volt-Amp | 6600 | | Item Weight | 4.11 Pounds | | Manufacturer | YueqingAoxunE-commerce Co.，Ltd | | Mfr Part Number | VFD220V | | Model Name | HKS-3KW-4HP | | Model Number | HKS-3KW-4HP | | Output Power | 3000 Watts | | Output Voltage | 220 Volts | | Peak Output Power Watts | 3000 | | Power Source | 220v,Vfd | | Recommended Uses For Product | CNC Router, Spindle Motor, Compressor | | Standby Power Shutoff | 90 | | Voltage | 220 Volts | | Wattage | 3 KW | ## Product Details - **Brand:** HKS - **Model Name:** HKS-3KW-4HP - **Power Source:** 220v,Vfd - **Recommended Uses For Product:** CNC Router, Spindle Motor, Compressor - **Wattage:** 3 KW ## Images ![VFD 3KW 4HP 220V 1 or 3 Phase Input 3 Phase 0-400HZ Output 20A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor and Spindle - Image 1](https://m.media-amazon.com/images/I/61HI+v98buL.jpg) ![VFD 3KW 4HP 220V 1 or 3 Phase Input 3 Phase 0-400HZ Output 20A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor and Spindle - Image 2](https://m.media-amazon.com/images/I/61A4DT+F5sL.jpg) ![VFD 3KW 4HP 220V 1 or 3 Phase Input 3 Phase 0-400HZ Output 20A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor and Spindle - Image 3](https://m.media-amazon.com/images/I/61BYLG57kCL.jpg) ![VFD 3KW 4HP 220V 1 or 3 Phase Input 3 Phase 0-400HZ Output 20A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor and Spindle - Image 4](https://m.media-amazon.com/images/I/61JFWt02DYL.jpg) ![VFD 3KW 4HP 220V 1 or 3 Phase Input 3 Phase 0-400HZ Output 20A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor and Spindle - Image 5](https://m.media-amazon.com/images/I/61NP+MzppdL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ excellent product *by R***R on December 14, 2025* Excellent, it works perfectly.
