Kundenbewertungen für VEVOR 4kW 18A 5PS Frequenzumrichter VFD AC 220–240V Frequenzregler Drehzahlregler Frequenzwandler Wechselrichtermotor VFD Inverter Variable Frequency Driver inkl. 20cm Steuerkabel

En el primer arranque con un compresor de dos CV estalló co una castaña y ahora no enciende ni la pantalla

Le convertisseur 4 Kw ne fourni pas l'Energie nécessaire au moteur de 3 Kw de mon compresseur: Err 1 systématique malgré divers paramétrages et montage en triangle. Le moteur fonctionne correctement sur le triphasé du secteur. Je souhaiterai l'échanger contre un 7.5 Kw mais le support m' envoie des consignes inutiles en anglais et ne répond pas à la possibilité de faire l'échange.

Este un produs chinezesc care nu își merită bani. Scrie că scoate 4 KW dar nu depășește pe unu de 1,5 kw, o problema și mai frumoasă e că nu ai cu cine să vorbești și nu poți face retur ( procesul de retur e aproape imposibila). Cu siguranță nu recomand vevor

Impossible de faire fonctionner un pont élévateur équipé d'un moteur triphasé de 3kw. Produit à oublier

It doesn’t meet CSA requirements! So my electrician refuses to install and I can’t install due to insurance reasons. It is basically useless to me.

Obtained this VFD to operate a 3hp Delta Unisaw with a 3phase 220V motor. The VFD does not provide any "enclosure" for connection of input power or 3-phase output. So I utilized a general purpose enclosure underneath the VFD to connect the conduit and bring the individual conductors to the VFD. That enclosure needs to have ventilation to provide for the fans built into the bottom of the VFD. How the VFD is constructed pretty much requires that the VFD be mounted in a vertical orientation, in order for the fans to effectively cool the heatsink. No mounting position requirements mentioned in the instructions. The terminals for connection to the VFD are a screw with a washer under the head. The best connection is a 6mm / 1/4" wide forked spade, although a solid conductor up to 10 guage can fit. If using a stranded conductor, it would be best to solder-dip the conductor for safe and effective connection. The screws for connection are quite short, only screwing out about 4 turns before totally unscrewing, and theres no "stop" to prevent one from totally removing the connection screw. Then, the design of the case is such that it is very nearly impossible to get a connection screw in once removed. Once those installation challenges are overcome, the VFD works great. Press start, and it takes 10 seconds for the motor to gradually come up to speed. A turn knob allows adjustment of speed. In my application, a shop table saw, it would be nice to have big, tactile buttons to push for start/stop, especially the stop. The front panel of the VFD has a membrane keypad, that one must look at and very carefully touch the needed button with a fingertip to get start or stop. There is the provision built into the VFD to connect larger pushbutton switches and relays, to implement more shop-safe start/stop start. Overall it accomplished what I needed, and once I adjust to the slight inconvenience of needing to be more diliberate and careful in turning on and off, will serve very well.

Prodotto corrispondente ma manca un manuale in italiano per l'installazione è abbastanza complicato, chiedere un reso

pour le moment je n'ai pas réussi à faire tourner le moteur en continu sans obtenir un défaut su le logiciel uccnc ma signalant la perte de données entre le contrôleur uc100 et le logiciel , à aucun moment la notice conseille un câble blindé vers le moteur et des ferrites sur la câble usb alimentant le contrôleur uc100 j'ai du faire une commande de câble blindé et des ferrites ; j'espère que tout sera résolu avec ces aménagements imprévus

Gerät ist einfach zu programmieren. Es fehlt ein Anschlussraum. Kabel sind nicht zu befestigen bzw. abzufangen. Not-Aus-Eingang, der sicherheitsgerichtet ist, ist nicht vorhanden.

This product arrived promptly and was easy to install/ setup etc. Purchased October 2025 and unfortunately failed today. The inverter was a replacement for a 10 year old Delta unit that has been running my lathe over that period. So I would have to say this unit is not in the same class as the Delta unit which were not that much more expensive than the Vevor.
