Peguei um inversor de frequência de 2CV com a etiqueta praticamente apagada. E agora? Como saber se ele é 220V ou 380V antes de ligar? Nesse vídeo mostro um caminho técnico usado em bancada: analisar os capacitores do DC-Link e a faixa de tensão suportada pelo barramento. ⚠️ Atenção: esse tipo de análise deve ser feito com o equipamento desenergizado, capacitores descarregados e por profissional qualificado.
