· Rugged industrial quality · Fieldproven internal modules · Cooling by convection only (no fans or forced air) · Full electronic protection · Dual output available This rugged, industrial quality DC/DC converter series generates 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 x 12" chassis. The design has large design headroom and is rated for operation over a wide temperature range without derating. The unit is built with two BAP 65F internal modules, which have a wellestablished 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 a 50% drop in output power while the unit remains functional at 500W. This design can also be used 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.
