Bonjour Je viens de vous re commander un variateur de fréquence en 7.5 kw Celui en 4kw commandé chez vous il y'a peu de temps étant déjà HS Je dispose pourtant d'un moteur 5ch J'attends une réponse de votre part Cordialement Mr Dehaud

Très bon achat , le convertisseur permet d'alimenter un compresseur tri-pistons à l'origine en 400V triphasé Modification du couplage moteur et Essais OK Juste la notice un peu juste , en anglais . Il a fallu bien chercher et essayer a tâtons , avec un autre moteur , pour trouver le bon fonctionnement.

Reçu rapidement Bien emballé Ce variateur 4kw est en remplacement d'un 2,2Kw Vevor qui ne pouvait pas démarrer un moteur de 3CH 2,2Kw Conclusion: il faut prendre la taille supérieure et régler l'ampérage Documentation en Anglais seulement , j'ai du traduire la documentation(pas facile pour celui qui n'a jamais fait d'anglais) J'ai appelé plusieurs fois , le téléphone reste muet, dans ces moments là on remet son achat en cause.

The manual could be more detailed on the parameters. The manual does not list all the parameters in the unit so im not sure if they are correctl set. . Im only running a straight 60hz motor with no adjustments to the Hz. For the short time using the VFD it is working perfectly. Much cheaper then buying a rotory phase converter.

Omvormer uitgebreid getest en met de menu functies goed te bedienen en installeren. Wordt hier gebruikt voor een 1,1 kW draaistroommotor op een kolomboor. Heb wel een ster schakeling toegepast omdat in driehoek (delta) de motor te warm wordt. Volgens de manual zou driehoek schakeling mogelijk moeten zijn? Blijft voldoende koppel over om ook grote boren met een rpm van 200 te laten werken. Een technische vraag over de omvormer werd binnen 24 uur behandeld door de klantenservice en verliep over drie afdelingen, was erg onder indruk.

I am surprisingly pleased by this VFD, so much I bought a second one for a backup just in case. This works great on a small milling machine with a 2 HP 3-P motor. The only complaint is the documentation is terrible. They instructions don't explain what programming features actually do. And the nomenclature (that's being nice, some of it is gibberish) is poor. But once you figure it out by experimentation, you get the drift. For the money, this is a nice unit. If you have a coupon or discount code, all the better. I mounted mine in an older tool post grinder box and moved the display out to the cover. I also transferred the controls to a separate box where I used momentary push buttons to control on/off and reverse, but the programming and potentiometer is still on the original display. This unit has surprisingly many ways to farm-out controls to remote switches using the X1 - X6 and SP1-SP2 terminals. Of note, the unit shows a terminal with a 12 VDC output and the manuals says that's 15 VDC but both are incorrect. The output on that B+ is 13.8 VDC, which I use to power a digital hall effect tachometer. Vevor needs to do a better job with the documentation otherwise, I'd recommend this unit for small machines with 3-P motors.

arrived promptly and well packaged. Works well and was very easy to programme, lacks some of the finer controls of the more advanced units (which are not really needed) but this aids in making the programming simpler , in fact you could use it straight out of the box and have it work. One essential thing that needs to be added is a cable support for the mains wiring. I added 3 cable glands on a right angle bracket mounted underneath the wiring terminal strips, easily done and adds a lot of safety.

First one we received had a malfunction, we returned and they promptly sent a new one which has been working fine.

Tutto ok

This is a good unit for the purpose. Well built, great price. However ... I see no reason VEVOR would ship a 50-cycle unit to the United States. The manual instructions to change to sixty cycle are worthless. I see no information on changing the ramp-up and ramp-down times. No information regarding if those times are necessary soft start Parameter change instructions need to be written for the average user not a technician.
