Advanced Energy introduces a non-isolated digital DC/DC converter for computing and communication equipment

     Advanced Energy has introduced its first industry-standard quarter-brick unisolated bus converter (NIBC) for 48-V power conversion in computing and communications applications. Artesyn NDQ900 DC/DC converter operates with power up to 900W and efficiency up to 97%. It provides single-way adjustable 12.25V output and has PMBus interface for flexible digital control and monitoring.

     Offering a wide input range of 40V to 60VDC, the NDQ900 NIBC is an ideal 48V to 12V converter for high power computing, networking, telecommunications, data storage, test and measurement applications. Its flat efficiency curve ensures that the 1/4 brick module provides ideal power conversion performance over a wide load range.

     "It combines ultra-efficient operation, thermally optimized design and digital control to meet the growing demand for 48-V power conversion solutions in data centers and enterprise computing systems," said Joe Voyles, Vice President of product marketing for Industrial Power Conversion at Advanced Energy. "The high power density of the NDQ900 enables top-of-the-line performance while minimizing power consumption in multi-load scenarios."

     The NDQ900 is designed with a substrate structure that facilitates improved thermal management and simplified installation of heat sinks. The module is forced-air cooled for superior thermal performance and provides full power in the operating temperature range of -40°C to +85°C.

     The NDQ900 is a fixed-frequency converter with no minimum load requirement. It has active current-sharing capabilities that help connect multiple power supplies in parallel for applications that require greater load current or redundancy capabilities. In addition to PMBus connectivity, the module also provides remote control capabilities and power status signals.

     The NDQ900 meets all international safety standards and integrates undervoltage locking (UVLO) with protection under overcurrent, overvoltage and overtemperature conditions. Advanced Energy supplies modules with a standard two-year shelf life.
