## Features

- 【4KW (5.5HP) Variable Frequency Drive】Input: 1-phase/3-phase 220 VAC (+/- 15%), 0- 17 A, and 50/60 Hz. Output: 3-phase 220 VAC, 0-17A, and 0-2,000 Hz.
- 【Low-Noise Operation & Low Electromagnetic Interference】 The PMW control technology and a component compatibility design allow this VFD for low-noise operation and low electromagnetic interference.
- 【V/F Control & Vector Control】 The VFD frequency setting mode includes digital setting, analog setting, serial communication setting (RS485 communication port, adopting standard international MODBUS main circuit control), PID setting (advanced calculus PID closed-loop arithmetic, quick responding speed, and high suitability), etc.
- 【Improved Safety & Durability】QNK VFD features protective functions for overload, fuse, over voltage (DC voltage>400V) or under voltage (DC voltage<200V), restart, stall, short circuit, and overheat. Moreover, it comes with copper coil internals and a nonflammable exterior for durability and a multi-grid design with enough cooling space between the electronic components and the case for fast heat dissipation.It also can prevent dust, water mist entering the circuit board section effectively.
- 【Wide Application】The VFD can be used in various types of equipment such as Spindle Motors, CNC Routers, Milling Machines, Pumps, Compressors, Grinders, among others.
- 【Attention】Please Note:1.This VFD surpport external resistor!!! If your motor is heavy load, pls choose a higher power level VFD or contact sales for model selection suggestion. 2.The VFD can’t be used as a power source for other equipment, or to drive a motor with a supply voltage lower than 80V. 3.Do not connect the VFD’s output terminals with capacitive loads.4.Choose a VFD with a larger power output when operating heavy equipment like the crane and compressor, e.g.,a 5.5 Kw motor should be connected to a 7.5 Kw VFD. 4.If a generator is used to power the VFD, ensure that the generator's output voltage level is within +/-15%.
- 【Customer Service】If there is an error code in the product and you do not know how to operate,or other questions of this product,pls feel free to contact us. Customer Support Team will help you as soon as we can within 24h.

## Questions & Answers

**Q: Can the vfd be used to drive a single phase induction motor for a fan?d**
A: Thank you for getting in touch.
Using a VFD for a single-phase fan motor isn't usually a good idea due to the motor's high starting current, which can stress both the motor and the VFD. If you still want to use a VFD, you must carefully choose one with a much higher power rating than the motor. For instance, if the motor is 1.5KW, go for a VFD between 3KW and 5.5KW.

**Q: Will this work on a wood turning lathe to make variable speed**
A: Thank you for your message. Our variable frequency drives work well with wood turning lathes that have spindle motors. If your lathe has a different motor or is a planer, compatibility depends on the motor's power. Please check your lathe's motor specifications or consult your lathe manufacturer or an electrician for guidance.

If you have more details about your lathe, feel free to share them for further assistance.

We're here to help with any questions you have.

**Q: Where can I download a manual for this?**
A: Hi, Eli G.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good instructions.  Works perfectly.
*by J***G on June 2, 2025*

I picked this up to run an Enco 3 hp vertical mill. After spending some time with the manual, I hooked it up without issue on the first try. My mills runs buttery smooth without hesitation. I like the ability to vary the speed with the turn of a dial. I remote mounted the VFD on the front of the mill for easy access. The included cable was just long enough to reach from the back of the mill to the face plate I made for the front by the master switch. I would and did buy again. Picked a 25 amp unit up for my 3 phase table saw I just drug home from an auction.

### ⭐⭐⭐⭐⭐ Works great
*by N***E on April 11, 2025*

Using this on a 3hp 3phase motor on an old lagun mill. Has been working great so far. Easy to do variable speed with. Probably one solution for those folks who have variable speed pulleys which don’t work correctly anymore.

### ⭐⭐⭐⭐ Functions properly
*by C***S on February 22, 2025*

Set up is a little confusing but once figured out has worked great for my 1hp mill
