C&D Technologies, EUS34-096
Fixed conversion ratio isolated DC/DC converter
News Release from:
12/10/2006
The EUS34-096 from C&D Technologies is a fixed 5:1 conversion ratio isolated DC/DC Converter. The module is designed for powering multiple downstream, non-isolated point-of-load (POL) converters in Intermediate Bus Architecture applications found in computer and telecommunications equipment.
 By incorporating input-to-output isolation of up to 2250VDC, the EUS34-096 allows designers to achieve important cost and space savings by allowing them to use non-isolated POL converters rather than larger, more expensive, isolated versions.
The new module, which has an industry standard eighth-brick footprint, specifies an input voltage range of 38VDC to 55VDC. It is able to deliver a maximum of 300W at 48VDC input, and minimum 240W output at 38VDC input, both at +55ºC and 200LFM airflow. Typical efficiency of the fully RoHS compliant Bus Converter is 96%.
The EUS34-096 features a positive or negative triggered primary side remote enable capability. The specification also includes over-current and over-temperature protection, both with automatic restart. The new module is suitable for parallel operation allowing it to satisfy the requirements of higher power applications.
Overall dimensions are 58.4mm x 36.8mm x 12.2mm and the operating temperature range is -40ºC to +85ºC. The EUS34-096 meets the requirements of the UL94V-0 flammability specification and has a demonstrated MTBF of 1.3 million hours.
