Sehr gut !
Die Stell-Trafos brummen nicht, sind sehr genau in der Einstellung der Spannungsscala (nachgemessen) und haben ein sehr gutes Peis-/ Leistungsverh?ltnis.

einwandfreies Ger?t
bisher erf_lt das Ger?t alle Anforderungen einwandfrei. Die Spannungsanzeige ist korrekt. Bei einer Dauerbelastung von ca. 100VA wird der Trafo leicht handwarm

Serves its purpose, but double check the output with an external meter
Bought for slowly waking up vintage valve radios after restoration. Have connected a dual pole switched 3 pin plug socket to the output winding.The transformer works as required but the markings on the dial are between 15V and 20V out depending where the variac is set. Worth checking the output with a digital multimeter before connecting anything where excess voltage may be critical. Normally valve radios will start to play at around 80volts and get louder as the voltage is increased. Once the set has tested for a few hours and proven to be safe I'll remove the variac and run directly on the mains.

Tadellose funktion
Funktioniert tadellos. Instrument zeigt genau an, 500 W sind ausreichend auch f_ leistungsstarke Verst?rker.Super Sache

Trafo f_ spezielle Einsatzzwecke
Solides Ger?t. Skala der Ausgangsspannung gem?? Messung bei meinem Ger?t korrekt.Muss abh?ngig vom Einsatzzweck durch Schutzkontakt-Stecker und Steckdose(n) erg?nzt und dazu evtl. auf einer Platte montiert werden. Ist daher eher f_ Bastler oder Profis.F_ meinen Einsatzzweck (flexible Herab-Regelung und ger?usch?rmerer Betrieb eines starken Ventilators, der selbst nur starr maximale Leistung erlaubt) gut geeignet.

Ce produit est arriv en ayant subi un choc lat_al gauche,apr_ d_ontage , recentrage de l'axe du rotacteur ,recentrage du noyaumagn_ique bobin ,comme l'aspect g__al me semble solide et bien con?uje lui met quatre _oiles, vu son prix imbattable.

A good ending
This turned up damaged 1st time and 2nd time but to be fair this was down to the shippers as the suppliers have been very good and have giving me a full refund

Buon Strumento da laboratorio
Dopo varie prove fatte posso dire che il variac funziona bene per carichi non superiori ai 400W

Buon prodotto
Ottimo rapporto qualit prezzo, di buona fattura. Si pu usare per moltissimi usi, con un raddrizzatore la tensione continua supera i 300 volt, regolabili a qualunque voltaggio. Molto utile nel laboratorio, per quel che mi riguarda, un ottimo acquisto!
