VFD Digital Phase Convertor 4kW 5HP 220V Single to 3 Phase

At this point I've installed 9 of these VFDs and they have been great. I had one arrive DOA, and I had one fail due to a roof leak that dumped water on it, otherwise, no failures in 6 years. The only knocks I'd give them are a very poorly written chinglish manual and a non-standard MODBUS interface. I did get MODBUS to work after about 2 weeks of heavy debugging and altering the protocol. Everything else works fine. One note - if you buy an HY series (instead of GT series) be sure to specify that you want the braking resistor circuit installed. While they advertise it has having braking they don't populate that circuit unless you specifically request it (no extra charge).

I had a problem with the VFD I bought. They said they would send me another. I had a new one delivered within 2 days. I got it installed and it works great! They did this with no hassle or cost to me. Thank You Huanyang

I wanted to give an update on my issue. Huanyang's customer service is top notch. They responded quickly and assured me that they would take care of the issue after Amazon was out of stock on the model that I order and really wanted. Huanyang customer service shipped me a replacement of the model that I originally purchased and wanted. Once I received the replacement VFD and verify it works as expected. I will update this post again. Based on my previous experience with Huanyang VFD I expect it to be excellent quality and performance. That was one of the reasons I was so disappointed when the first one did not power on. I will let everyone know as soon as I get it if it meets my expectations.

My objective was simply to control the speed of a 3-phase motor; so this VFD was very easy to get running. I tried using 10/2 SOOW wire to connect the VFD to the power, but it was a bit too large. 12/2 worked great...using the E, R, and T for ground and the two hot wires. I connected the other end of these wires to a 30A plug so I could move it easily if I wanted to. After connecting the UVW terminals to the 3 input wires of the motor, it was all ready to go. I would have liked to see some type of strain relief for the wires going into the VFD. Also, a variable speed fan would cut down on some of the noise when the VFD isn’t being pushed to its limits. All in all, I would buy it again.

I installed this on my cnc milling machine to run a 5 HP 3 phase motor. I use Mach 3, a C10 and a C6 board to control this VFD and it works very well. Excellent bargain for the money.

Works great, easy setup, I'm using this to run my milling machine.

Purchased to replace a no-name clone that blew up after only a couple hours. This is my third Huanyang VFD now, and they've been rock solid for me (2000+ runtime hours on my oldest unit, still going strong).

The one star is more for the deceptive nature of the seller than for the product. Except for lacking dynamic braking, the vfd is fine. All indications in the listing lead one to believe the unit comes with dynamic braking. The manual for the GT series describes how to configure for dynamic braking. One of the illustrations in the listing shows external resistors installed. However, it turns out that the GT series comes in two versions, one with and one without dynamic braking. The seller is aware that at least some customers are expecting to receive a unit with dynamic braking capability, (see his answer to the question about braking. Yet he has done nothing to be sure customers are aware that he is shipping the crippled version. The seller is being intentionally deceptive . If you buy a GT series, but from someone else and be s sure you are getting dynamic braking.

I am impressed with how well this works but am curious to see how long it will last. So far so good though

Works very well for my 3 Hp motor. Able to start, stop, reverse direction and control rpm using cnc programs with centroid acorn.

installed on my 3 hp engine lathe. works excellent. asked a few questions by e-mail ,recieved very prompt responses.will buy another for my mill

I haven't yet installed it. It was purchased to replace another vfd that the display has quit on. I am still using the original vfd but this one is in standby in case it totally fails.
