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.

They arrived and worked. I had these old molloms, these were less complicated and easier to use, with clearer labeling for the one phase power connectors. Both worked for my purpose. I returned them, but only because the owner of the building I was in offered to pay for them to replace one of the broken ones.

It works fine but the instructions for the settings are unclear

got the 5hp unit to run my 3ph 5hp compressor since my home shop doesn't have 3ph. manual is terrible but there are so few settings its not too bad to figure out, however once the belts were tight it started immediatly over currenting trying to run my load. even with loose slipping belts it was extreemly sensitive to the settings on the unit to run it even at lower power.
