Power supplies deliver full-rated power with 10cfm cooling

The new 55W single-output ac-dc power supplies from Power-One Inc. utilize "superior thermal-management techniques" to deliver full-rated power with only 10cfm cooling.

Benchmarked with all available outputs—5-, 12- and 24V, members of the BLP55 series are designed to meet the rigorous requirements of networking, data communications, commercial, and industrial applications.

According to the press release, reduced airflow requirements facilitate greater overall-system layout flexibility as the BLP55 does not have to be located directly adjacent to the system cooling fan. Depending on system configuration, the device may also eliminate the need for a dedicated power-supply cooling fan, especially in space-constrained 1U applications.

A compact 76.2-by-127-by-31.8mm package combines enhanced features and performance with compliance to established industry-standard footprints and connectors. Standard features include remote sense, internal overvoltage protection and 85Vac to 264Vac wide-range input.

The BLP55 is priced at $27 each for 100-piece quantities. Evaluation units are available from stock, with production quantities typically available in 10 to 12 weeks.
