Customer Reviews for Variable Transformer 500w Power Supply Voltage Transformer 220v One Power Plug

tr_ bon produit, d'une bonne pr_ision pour du CA. Moins 1 _oile pour la prise 220 v qui aurait pu _re de meilleure qualit et norm march europ_n. Je recommande ce produit.

Sehr gute Wahl.Ich nutze den Trafo f_ alles M?gliche, haupts?chlich f_ das langsame anfahren von elektrischen Ger?ten um zu sehen was passiert.Ich habe allerdings den Hauptschalter auf 2 Polig gewechselt und den Sicherungshalter gegen einen kleinen Automaten getauscht. Das liegt aber eher daran, dass ich den Trafo auch manchmal etwas _erlaste.Die Verdrahtung im Innern ist v?llig O.K. und entspricht meinen Sicherheitsanforderungen.Die digitale Spannungsanzeige ist allerdings nicht wirklich genau. Da sind 5 Volt Toleranz einzurechnen. daf_ stimmt die Skala oben auf dem Handrad.Klare Kaufempfehlung.

I restore vintage radios and needed a new 'variac' for safely waking these delicate devices after a prolonged 'sleep'. This 500W unit is fabulous value for money and would have scored 5 stars but for a couple of small niggles - well one small niggle and one fairly large one. That is that the transformer winding is way too close to the vent holes on the base of the unit. This could pose a safety hazard if objects were to be trapped under the unit. ( I have fixed my transformer under the workbench where this cannot happen.) The other niggle is the scale on the top is wildly inaccurate! Fortunately the digital voltmeter is considerably better, but I recommend you check its accuracy against a reliable meter as even this is not perfect. It is slightly awkward having the control on the top and the meter on the side, but given that the meter is really a bonus I can forgive it that issue.Having over-witten the numbers on the dial with my finest Sharpie (other permanent markers are available) I find this is now a really useful tool in the workshop, and I don't want to be without it.

Per un tecnico radio TV computer il variac e essenziale per un banco di lavoro elettronico. Permette di testare e esperimentate alimentatori flay back senza alimentare dall 220 volta alternata di rete ma di testare con un voltaggio un po inferiore sempre in CAUTELA L alimentatore in sicurezza .

Tutto bene grazie

Finition la serpe, mais c'est du costaud.Tr_ surprenant (agr_blement), malgr la provenance directe de Chine, la livraison a _ effectu_ en moins de 72 heures. Install de suite, j'ai pu b__icier de l'eau du puits en plein _.
