Problema VDF

Recommended Posts

Cu ce modificari se poate lega un convertizor trifazat la reteaua monifazica ? Eu am incercat sa pornesc un Vdf Omron trifazat la reteaua monofazata dar intra direct in avarie . Am citit undeva ca avea un vdf trifazat legat la mono si merga de ceva timp .

Daca e construit numai pentru 400V nu-l poti pacali. Majoritatea celor moderne se pot alimenta de la 400V si de la 230V, caz in care se foloseste o singura faza (L3 si N) de ex . Pe bornele de alimentare daca nu apare N (null) si sunt doar L1, L2, L3 si PE e clar ca este destinat doar alimentarii trifazate.

Da , este dedicat alimentarii trifazate asta stiu , dar totusi cum au reusit uni sa alimenteze pe L1 faza L2 nul L3 liber si sa nu intre in avarie . 

Am si vdf monofazat dar ala nu intra in discutie.

Am probat 6 vdf-uri trifazate cu puteri intre 4-22kw toate intra in avarie la alimentare monofazata. Nu inteleg el cum o reusit sa il pacaleasca fiind si al lui trifazat dedicat 4kw
