Question
Boa noite. Gostaria de saber se esse transformador gera 3 fases equilibradas como num sistema L1 L2 e L3 mais N. Cumprimentos Flórido
Answer
Bom Dia. Este produto é um autotransformador trifásico reversível de 1 KVA 230/400, se as fases estiverem desbalanceadas na entrada, também estarão desbalanceadas na saída. https://adajusa.pt/pt/autotransformadores-monofasicos-e-trifasicos/4460-transformador-automatico-trifasico-230-400v-1-kva-reversivel-com-caixa-8435532844600.html Saludos Adajusa

Question
buenos dias. estos transformadores cono funcionan? la entrada puede ser 220 monofasica y salida 380?
Answer

Buenos días,

Este tipo de elementos solo adptan el nivel de la tensión, pero no convierten de monofásica a trifasica. Supongo que sera esta la pregunta.

Saludos
