This rugged, industrial quality DC/DC converter series generates up to 1kW output power with convection cooling (no fans). Several
units can be paralleled for higher output power. It is housed in a compact, ruggedly constructed 7” x 7” x 12” chassis. The design has
large design headroom and is rated for operation over a wide temperature range without de‐rating. The unit is built with two BAP 65F
internal modules, which have a well‐established track record in numerous other heavy duty applications. Each internal module
generates a minimum of 500W. This modular construction provides inherent redundancy; the failure of one internal module would
result in a 50% drop in output power while the unit remains functional at 500W. This design can also be used as a 500W redundant
power supply. Two independent fully regulated outputs of 500W each are also possible. Full electronic protection eliminates failure
due to abnormal operating conditions, including application errors. The input and output are filtered for low noise. Additional
ruggedizing and conformal coating are available for applications that require high immunity to shock, vibration and humidity. Other
options include a Form C output fail alarm to indicate module failure, as well as remote shutdown. Low component count and the use of
components with established reliability result in a high MTBF. Versions designed to meet EN 50155 railway specifications are also
available.
