Reseñas de clientes para VEVOR Transformador de voltaje variable automático de 1000 VA, 3,3 A, entrada de 230 V, salida de 0-300 V, regulador de voltaje de CA LCD 4 fusibles, interruptor de control térmico para oficina

Very heavy duty, nice construction and I like the digital gauge, its bright and easy to read. Checked output voltage with DVOM and it matches the display very close all the way through the range with voltages over 100 very accurate.

Appareil parfait répondant à toutes mes attentes. Idéal pour le demarrage des installations révisées. Emballage soigné et livraison rapide.

Funciona bien y el bobinado que es la parte más importante es de cobre, la escobilla deslizante tiene un disipador de calor de aluminio que parece de suficiente tamaño para la potencia del transformador.

This is without a doubt a really nice unit. It does exactly what it says....the digital readout is super nice to have. I would not buy one of these units without the digital readout. I am extremely happy with the overall quality. Great unit, fair price. Great experience. Would buy again for sure. Bill P.

The voltage adjustment dial is not at all in the middle of the scale, so the preliminary setting is quite difficult. It's an ugly cosmetic flaw, although the device itself is good. The 6-volt scale also doesn't help with the setting.

ci sono stati dei problemi inerenti il funzionamento del Variac che sono stati risolti egregiamente ,per questo voglio ringraziare chi mi ha dato tutta l'attenzione necessaria per risolvere i problemi riscontrati. Grazie di nuovo a VEVOR e a lo staff di supporto.

Works perfect, price acceptable, i happily would pay some extra money to have a digital voltmeter and amperemeter

Il prodotto funziona bene. Si sente molto rumore per assorbimenti prossimi a 10 A. L'assemblaggio dei componenti potrebbe essere un po più preciso. A 230 Volt può essere applicato un carico massimo di 2300 Watts. In ogni caso fa il suo dovere tanto che ne ho comprato un secondo.

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
