Klantbeoordelingen voor VEVOR 1000VA variabele spanningstransformator, 3,3 ampère, 230 V ingang, 0-300 V uitgang, AC-spanningsregelaar, voeding, met 4 extra zekeringen, voor thuis, industrie en kantoor

Goed apparaat , werkt prima, alleen demeteraanwijzing verschilt van de werkelijke waarde, dus een parallel een universeelmeter plaatsen.

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

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

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