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.

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.

I used it for my cylinder head grinding machine and it worked without any problems. ### ⭐⭐⭐⭐⭐ Works great and support was very helpful! *by J***H on March 2, 2023* 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. ) ### ⭐⭐⭐⭐ No strain relief for the AC line input wires nor the motor output wires. *by J***Y on January 17, 2025* I bought this VFD to replace the Westinghouse/TECO N3 VFD which failed on my 2HP Bridgeport milling machine. I think the unit is actually the ISACON A2 Series, I'm not sure if HKS rebrands it or if HKS is part of ISACON? This unit is considerably smaller than the TECO N3 and only has 2 mounting holes. There is no strain relief for the AC line input wires nor the motor output wires. I used the strain relief bracket off of the TECO, but this still leaves the wires exposed. I took off one star for no strain relief. I'd also prefer it if all the wires were completely enclosed. With the wires exposed, I'm not sure if this unit meets US UL wiring code or not? The terminals for the AC line input and motor output are also quite small, I used forked terminals for a US #6 stud (or you could use whatever the metric equivalent is), this means you'll probably have to use #12 GA wire or less. I followed the instructions given in the "Set The Initial Test Parameters" found on the Amazon page for this unit, I just changed the PN02, PN10, and PN12 parameters to 60Hz instead of 50Hz (I'm in the USA). The instruction manual is very brief but adequate for what I needed, but could be better explaining some of the more advanced features. The turn on and turn off acceleration default to 10S and are much slower than the TECO unit, but these can be easily changed with PN08 and PN09. I used an external pot on the TECO N3 to change the frequency and thus the motor speed, but this can be done on this unit with the UP/DOWN buttons on the front panel, which is nice feature. You can also set it up to use an external pot if you want to. Initially I like the way the unit works, the front panel seems fairly intuitive, and everything worked as I expected. The price is certainly appealing, much cheaper compared to something like the TECO. It will be interesting to see how it holds up in the long term, but I would certainly recommend it at this point especially for a home machinist such as myself. ## Frequently Bought Together - VFD 7.5KW 10HP 220V 1 or 3 Phase Input 3 Phase 0-400HZ Output 50A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor Speed Control and Spindle - Steel Electrical Junction Box, Indoor&Outdoor Electrical Enclosure Box, Wall Mounted Waterproof&Dustproof Metal Box, Universal Electric Equipment Enclosure Box with Safety Locks and Mounting Plates --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/367215964-vfd-7-5kw-10hp-220v-1-or-3-phase-input](https://www.desertcart.co.uk/products/367215964-vfd-7-5kw-10hp-220v-1-or-3-phase-input) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
