Los transformadores ke300a - 08 se utilizan para estacionar y no estacionar temporariamente, utilizando un algoritmo de control de alto rendimiento que maximiza la eficiencia de la utilización del voltaje vertical de corriente continua basado en el principio básico del control de la tensión matriz de corriente continua.Después de un análisis combinado basado en la medición de la tensión de la línea madre de la corriente continua, el Estado de salida de la unidad se ajusta automáticamente para establecer una relación razonable de distribución de la energía de retroalimentación de carga, de modo que el controlador del motor se mantenga sin interrupción de 4 a 9 segundos.Cuando la unidad esté completamente desconectada y no se muestre, la red se reiniciará automáticamente.Durante todo el período de avería eléctrica instantánea, el conductor no notifica la avería.
