Artesyn Embedded Technologies today announced the AVO75 series, new 75-W fully-regulated eighth-brick dc-dc converters that bring high efficiency and thermal performance to cost-sensitive, small space, high current and low voltage telecom network infrastructure applications. The AVO75 series is capable of delivering up to 25A output current and a single adjustable output between 1.2- and 12-Vdc from a 2:1 range input of 36- to 75-Vdc.

Above 92 percent efficiency and excellent thermal performance in an operating range of minus 40 to 85 degrees Celsius makes the AVO75 series suited where the highest efficiency is demanded by network equipment manufacturers and carriers. For example, these units can deliver their full usable output power from a 48-Vdc input at 55 degrees Celsius ambient temperature with a standard 200 linear feet per minute (LFM) airflow cooling.
