Advanced Energy has released Artesyn NDQ900 non-isolated bus converter (NIBC). The digital DC/DC converter comes in an industry-standard quarter-brick format for 48 V power conversion in compute and telecom applications. The bus converter can supply power of up to 900 W with a high efficiency of up to 97% across a wide load range. The NIBC features the PMBus interface for flexible digital control and monitoring, the module also offers a remote-control function and a good power signal. The Artesyn NDQ900 is suitable for use in test and measurement equipment, data storage, telecommunication, high computing equipment, etc.

The Artesyn NDQ900 DC/DC converter provides a single, regulated 12.25 V output. The module can work with input voltages ranging from 40V to 60V. The module also features improved thermal management, allowing it to work over full power over an operating temperature range of -40 °C ~ +85° C.

“The combination of ultra-high-efficiency operation, thermally optimized design and digital control addresses the growing demand for 48 V power conversion solutions in data centre and enterprise computing systems,” said Joe Voyles, vice president of marketing, industrial power conversion products at Advanced Energy. “The high-power-density NDQ900 optimizes performance while minimizing power consumption across multiple load scenarios.”

Artesyn NDQ900 is the company’s first NIBC in a quarter-brick format for 48 V power conversion in compute and telecom applications. It features a wide 40 V to 60 V DC input range and is ideal for critical applications including high-power computing, networking, telecommunications, data storage, etc. A flat efficiency curve ensures that the quarter-brick module delivers optimum power conversion performance for a wide range of loads. The NDQ900 is a fixed-frequency converter with no minimum load requirement. It features an active current-sharing capability that facilitates the connection of multiple power supplies in parallel for applications requiring higher load current or redundancy.
