    boy was i happy this thing worked. i live in canada and have 220v split phase to my garage. hooked the vfd up and it powers up the little horizontal mill no problem. output was 400v at 60Hz, which is great. speed control works really good. my mill has a 2 speed motor, so i have to stop the vfd before i switch to the second speed or reverse with the mill control switch. VFD forward and reverse work and so does the deceleration time, which is pretty nice feature. the front panel is very cheap, but works. i ordered some nice push buttons and a potentiometer to make a wired control panel. motor i have is 380v three phase of unknown config (delta or wye) but worked with this unit. its supposed to run at 0.7Kw (2.4A) at 695rpm, and 1.1kw (2.4A) at 1400rpm, but it drew 3.5 and 4.0 amps respectively at 50hz each. i think this is fine. motor was very torquey at all speeds, i was not able to stall it with a 2x6 levering on the spindle sheave. the max amps it drew while i was trying to stall it was 4.2A. i am glad i over rated the drive for the motor demand, as it seems to be a bit hungry when not on real 3ph and it could have gone over a smaller spec one. the only thing i would have wanted is for it to use a standard type of plug for the control panel, so i could just remote mount the control for now, before i make the new panel. as i really want to install the drive way below in the casting as it makes a quiet but really annoying noise. sounds almost like bad bearing noise. had to pay duty or clearance whatever, of 40$ i think? i cant recall the exact amount. just expect that. would have been 5 stars if the case was better, the wire terminations were big enough for crimped wire ends, and if the panel used rj45 for an extension cable instead of random ribbon type. Either way, this will take my canadian spaghetti power and turn in into weird european 380v3ph and run a pretty decently powered mill. i am happy as long as it lasts a year or two for this price!

    I am using my AT4 to control the motor of my lathe and the motor of my mill. This is possible, since I do not run both motors at the same time.

    Cet inverter est parfait pour faire fonctionner une perceuse en triphasé 380 V à partir d'une ligne monophasée 220V. Le moteur démarre sans broncher et sans perte de couple. Le variateur de fréquence est très pratique car il permet de faire varier le régime du moteur sans changer les courroies. A faible régime le couple reste très correct et l'inverseur sur le tableau de bord est parfait pour engager et dégager un tarot. L'inversion du sens de rotation fait diminuer progressivement le régime du moteur et le relance dans le sens opposé à la même fréquence, juste en appuyant sur un bouton. C'est parfait et beaucoup mieux qu'un montage avec un condensateur pour tenter de démarrer un moteur triphasé sur une ligne monophasée. N'hésitez pas.

    We can't use our new inverter Its for the waste . . The default max voltage parameter is fixed set on 380V and OK but the outlet is 3PH 600+V we can't change it ??? . We don't receive a solution for this problem ;Only try again with the manual . There is no technical support for this problem only sales . After two weeks we don't receive a solution for this problem ?? We prefer to return the inverter cost free .No cure no pay .No answer ..

    Bien reçu dans les temps, le produit est conforme à mes attentes. Il serait pertinent de fournir une notice en français avec les explications des borniers pour les commendes déportées.

    consegnato in 6 giorni, peccato per i costi di sdoganamento, arriva corredato di un misero foglietto di istruzioni peraltro sbagliato in alcuni punti, ma sembra un buon prodotto.

    The joy of acquiring the transducer wasn't long. From the beginning everything was good, and then the frequency increased and the speed did not increase. The engine rotated at low speeds that did not match the displayed frequency. The current consumed by the engine rose sharply to about 13 amperes, for each phase..Checked without load. I'll check the remote circuit tomorrow and the mains engine under load.
