Review: Instructions a little difficult to read, but once it’s figured out product works very well. - Works well for my air compressor. Instructions are a little difficult to read, but once you figure it out, it’s pretty smooth sailing from there. The only trouble I had was with the control circuit, which is literally just a loop. I thought I had to hook up an external power source for the control circuits, but it’s literally just a loop with a switch in it, which in this case was the compressor pressure switch. Only power supply I had to hook up was for the 220 V. The unit itself is constructed of plastic, but it does not feel very cheap, it is actually quite a sturdy piece of equipment. I used a 10 hp unit for my 5 hp compressor. No overheating issues, and it also includes an internal temperature reading so you can monitor while it’s running. I would definitely purchase this again.
Review: Good instructions. Works perfectly. - 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.

## Features

- 【2.2KW (3HP) Variable Frequency Drive】Input: 1-phase/3-phase 220 VAC (+/- 15%), 0-11 A, and 50/60 Hz. Output: 3-phase 220 VAC, 0-11A, 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.
