If you have an old school star configured 400v motor with the neutral point buried in coils, this is the inverter for you. It outputs circa 380 to 415v from a 220v input. It works very well to drive my 550W 3p drilling machine, but I am not convinced I have been able to set the device up to the best advantage due to the poor manual. here are the other issues 1) The earth location is not obvious and is hidden away off the main power block and located on the end of the relay block of the low power connection terminals... JEEZ WTF! 2) Out of the box it works OK but, the parameters loaded on mine were not at the default settings indicated in the manual. I only found this out after doing a reset to factory parameters. On rerun, the current and voltages were incorrectly displayed on the keypad and there was no range to the VF pot. Secondly, the start and stop ramp frequency was reduced by a factor of 10. Sort of solved the first problem for parameters 68 to 75 because I could remember approx. what they had been prior to the reset. second problem I couldn't solve, but worked around by setting the ramp frequency to 150Hz/s, this gave a start ramp from 0 to 50 Hz in 4-5 seconds. The problem suggests there is a hidden parameter that is sitting above the ramp speed table. 3) the manual is very, very poor. They would sell a lot more of these devices if they took the time to produce a more detailed manual setting out examples for the control methods available and explaining the parameters better - particularly in the 68 -80 block, which are mostly completely obscure, but appear quite significant.

Good for the money but some slight variations in quality - some examples have too much play for the most precise operational requirement. They are perfectly suitable for recreational RC flying but wouldn't use on competition F3F/3B machine!
