Based on a standard quarter-brick format, the Advanced Energy Artesyn NDQ900 non-isolated DC/DC converter provides 48-V power conversion in compute and telecom applications. The device delivers up to 900 W of power with efficiencies as high as 97%, along with a single regulated 12.25-V output. In addition, a PMBus interface allows flexible digital control and monitoring.
The NDQ900 non-isolated bus converter has a wide input range of 40 V to 60 V. A flat efficiency curve ensures that the quarter-brick module delivers optimum power conversion for a wide range of loads. The module’s baseplate construction improves thermal management and simplifies heatsink attachment. With forced-air cooling, the NDQ900 supplies full rated power over an operating temperature range of -40°C to +85°C.
The NDQ900 is a fixed-frequency converter with no minimum load requirement. Active current-sharing allows the connection of multiple power supplies in parallel for applications that require higher load current or redundancy. Approved to all international safety standards, the NDQ900 comes with a two-year warranty.
