BRAKING UNIT FR-BU2 MITSUBISHI
Braking Unit FR-BU2 là thiết bị có khả năng xả dòng điện trên DC bus của biến tần cao hơn so với điện trở xả qua transistor. Thiết bị được kết nối mà không cần biến tần có built-in “ brake transistor”. FR-BU2 là bộ điều khiển hãm cho các dòng biến tần thông dụng của Mitsubishi như FR-A800, FR-F800, FR-E800, DR-E700, FR-D700 … Ngoài ra có thể tương thích với các dòng biến tần của các hãng khác.
