Description
Great Oak Curated Industrial Equipment:
Part of our industrial collection, selected for durability and performance.
Features & Details
- Powerful Function: This variable frequency drive accepts 1- or 3-phase input and delivers 3-phase output. Control modes include V/F control and vector control. Frequency setting options: digital, analog, serial communication, and more. Multiple control techniques—both synchronized and non-synchronized—enable rapid startup without brake adjustments.
- Low-Noise Operation: The CNC variable frequency drive inverter features low noise and low electromagnetic interference through the optimization of PWM control technology and electromagnetic compatibility of the overall design. Sufficient spacing between electronic components ensures effective heat dissipation, and the shell incorporates porous heat dissipation, extending service life.
- Smart Digital Display: The VFD features a user-friendly keyboard layout with fully functional, clearly marked buttons for quick and intuitive operation. The large digital display is highly legible. The detachable panel design facilitates remote control.
- Multiple Protection: We employ various protective measures to ensure the stable and reliable operation of the CNC frequency drive inverter, including overload protection, fuse protection, over-voltage (DC voltage > 400V), and under-voltage (DC voltage < 300V).
- Versatile Use: Suitable for spindle motors, CNC engraving machines, CNC milling machines, CNC machine tools, milling machines, drilling machines, trimming machines, mixers, extruders, slitting machines, rewinders, compressors, ventilators, pumps, grinders, and conveyors.
- Speed regulators compatible with elevators (excluding passenger elevators), centrifuges, and similar equipment.

Detailed Overview



2.2 KW Variable Frequency Drive
Stable Performance & Digital Display & Mute Operation
This VFD converter can be used for constant torque loads (such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc.). In addition, it can be used as a motor speed control and a phase converter. The input for this VFD is 1 or 3 phase, and the output is 3 phase. You can control the different speeds you like when you use this VFD. This item uses Sine wave PWN(SPWM) to perform excellently in the control system.

Premium Quality
This VFD drive adopts ABS flame retardant material case, which is high-impact and durable. And it uses the US intel and SILICON LAB’s chip. The input for this VFD is 1 or 3 phase, and the output is 3 phase.

Powerful Performance
This inverter VFD uses a unique control method to achieve the high moment of force, high precision, and wide speed regulating range driving. In addition, it has a powerful anti-jamming capability, low output ratting torque, and low speed running ability.

High Air Volume
The spindle VFD is equipped with fan cooling and a built-in radiator. It has an efficient heat dissipation ability, ensuring a suitable temperature inside the VFD. In addition, the independent air duct is designed for electrical and contaminant isolation, allowing the product to be used in harsh environments.

Smart Digital Display
After the panel is disassembled, it can be connected to the corresponding interface to achieve remote control. Reasonable layout and intuitive & clear digital display increase the convenience of daily use.

Multiple Protection
Many protection ways are adopted to ensure the stable and reliable operation of the CNC variable frequency drive inverter, like overload protection, fuse protection, over-voltage or under-voltage protection, restart protection, etc.

Wide Application
The variable frequency drives are applied in machinery winding machines, mixer, extruder, slitter, winder, compressor, ventilator, pump, grinder, elevator, and other speed control machines.

Excellent, very good, arrived perfectly in good condition and arrived very well exactly what I wanted, thank you
Verified Customer –
Good quality for the money. Unfortunately never received refund on first order. First order went to wrong address and was returned to the factory.
Verified Customer –
All is good both products tested very well so I am happy. not finished with the project so I will have to wait for the full setup.
Verified Customer –
User manual was complete and understandable, easy to wire and had my 2HP motor running in minutes. I opted for this because I’m controlling with a CNC controller 0-10V output. If I was going to manually control it, I would have purchased a VFD with a speed knob.
Verified Customer –
I have purchased several of these units and have sold several friends on their great qualities. This has been in use for 3 months and is totally dependable. Single-ph. to 3-ph. and full speed control. The newer versions have a dial for speed that makes it even nicer. Incredible buy, especially compared to a rotary converter. Highly recommended, like all Vevor products I have purchased.
Verified Customer –
Prompt delivery, Works great, Hook up wasn’t to bad, instructions could be a little clearer.
Put it on my 14″ Delta Rockwell band saw so I can power the 3ph motor with single phase 220.
Just have to see how long it lasts. All and all I am totally satisfied.
Verified Customer –
This inverter works great I use it to power a handful of things in my shop I Installed it in a junction box With 220 v twist lock plug-in And a three phase 220 twist lock plug out
Verified Customer –
Set up for a blacksmith style 2×72 belt grinder and it works awesome. Easy to use. Might need some youtube to make sure your doing everything right. The instructions could be better
Verified Customer –
Looks to be just what the doctor ordered. This is in inventory for a customer service support program..
Verified Customer –
Used this to power up 3phase robot with the addition of some components and have had nothing but great luck with this VFD. i keep it accessible to test 3 phase equipment in my home shop and could not imagine my setup with out it. Great buy. Wish they weren’t out of stock.
