Artesyn Embedded Technologies today launched the ADQ600 series, new 600W quarter-brick isolated dc-dc converters with the high efficiency and thermal performance demanded by telecom network and data center equipment. Capable of delivering up to 50 A output current with a single fully-regulated 12 V output, the converters have no minimum load requirement. The ADQ600 series has an input voltage range of 40 to 60 V and is primarily designed for use with standard 48 V supplies in computing and server applications, as well as regulated 48 V supplies in telecom equipment.

A typical efficiency of 95.6 percent at full load and the ability to operate over an ambient temperature range of minus 40 to 85 degrees Celsius, makes them suited for use as the isolated converter in a distributed power architecture supplying power to non-isolated converters. Their open-frame design is optimized for forced air or conduction cooling and an aluminum baseplate option is available for enhanced thermal performance. The conversion technology employs 175 kHz fixed frequency switching to help minimize external EMI filtering requirements.

Artesyn ADQ600 series converters are low profile units suited for systems with demanding inter-board spacing requirements; the open-frame models have an installed height of 0.43 inch (11 mm), while the baseplate versions require 0.52 inch (13.3 mm).
