Reseñas de clientes para VEVOR Transformador de voltaje variable automático de 2000 VA, 6,6 A, entrada de 230 V, salida de 0-300 V, regulador de voltaje de CA LCD 4 fusibles, interruptor de control térmico para oficina

Great value for the price. But be aware, especially for the EU model/plug. The EU plugs are symmetrical so you cannot be sure which one is the live or the neutral. And the transformer's main switch switches only one of them. And depending on your 'luck' or 'un-luck', it may break the neutral and not the live wire. And you may mistakenly think you are safe as you switched off the variac, but in reality your device is still on the live wire. So be very careful. My other note is that without any load it trips the breaker on startup sometimes. I think this is because the high inrush current of the transformer. So you may need an inrush current limiter or start always by setting the transformer to zero and increase the output voltage after you switched it on first.

I use this to dial down the voltage for use with antique fans many fans from the turn of the century where made to run on less than 120 volts

Très bien

The device works; I set it to 220V (measurements show an output voltage variance of ±2V, i.e., 217/218V). shipping box was not damaged, What annoys me is the fact that the casing is dented on all sides, all dents are made before shippment. they are low in quality control. I cant resolve casing to original form .I have requested to return and a refund .

L'articolo è arrivato danneggiato e non riusciamo a fare la pratica di reso o sostituzione

Niet goed gemonteerd zit er scheef in. Weet niet of ik dit kan veranderen. Beetje erg slordig voor zo n bedrijf Oplossing ????

The transformer is constructed with a one phase breaker, so even though you swith the unit off, the output is potentially still at mains voltage.

Unterste Qualitätsklasse. Flackert bei Niedriglast aufgrund der minderwertigen Schleifer. Extrem hoher Einschaltstrom Fragwürdig ob hier die europäischen Anforderungen bezüglich Berührungsschutz und EMV eingehalten werden.

Vevor won't tell you that their singe phase ac motors cannot be controlled through voltage. They can't be controlled through VFD either. When attempting to exchange this for a 3 phase motor with VFD they offered me $63 for my $200 order and that I'd have to pay shipping.

We never received the items purchased. Vevor passed the delivery on to OnTrac, a third party for delivery and they dropped the ball. They changed the address we provided. We spent hours trying to track the shipment as well as customer support from Vevor as well as support from OnTrac. Really a poor experience. A month later it is still unresolved.
