The BAP-3KR-3U4 is a railway quality DC-DC converter that uses a field technology to deliver the required output power. It is a mature design with a track record in numerous applications. The unit is built with four internal modules that also provide inherent redundancy; the failure of one module would only cause a minor loss in output power. Several shelves can be paralleled for higher output power. Built‐in fans provide sufficient airflow for operation without de‐rating to the specified temperature. Full electronic protection eliminates failure due to abnormal operational conditions, including application errors. The internal models are fully ruggedized and conformal coated for immunity to shock, vibration and moisture. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF. It meets the requirements of EN50155 for electronic equipment used on railway rolling stock. The unit is manufactured at our plant under strict quality control.
