Advanced Energy Industries has introduced two new non-isolated bus converter modules, the NDQ1300 and NDQ1600, which provide high-efficiency 48 V to 12 V conversion for data center, server, and networking applications. The modules are designed to address the needs of advanced information and communication technology (ICT) hardware, including artificial intelligence servers and high-performance compute, as well as industrial applications such as robotics and test equipment.
According to Advanced Energy, both the NDQ1300 (1300 W) and NDQ1600 (1600 W) modules achieve peak efficiencies up to 98 percent. The quarter-brick form factor targets scenarios where space and power density are key design constraints. Each unit converts a 48 V input to a fully regulated 12 V output, suitable for non-isolated, low-voltage, high-current stages, PCI Express slots, and memory devices commonly found in high-density racks.
The NDQ modules incorporate a flat efficiency curve to maintain high performance across a broad load range. Technical features include an integrated Power Management Bus (PMBus) interface for digital control and monitoring. Current-share and remote sensing capabilities support operation in parallel for either increased load current or redundancy. The transformer-based topology is designed for safety and resilience to transient loads, simplifying integration of inrush current control at start-up.
For thermal management, the converters include an advanced baseplate for heatsink integration and improved heat dissipation. The use of standardized dimensions is intended to enable straightforward scaling for future deployments and maintain protection for downstream circuits.
Joe Voyles, Vice President of Industrial Power Conversion, System Power at Advanced Energy, said, “Today’s power system designers are focusing on efficiency and form factor as they look to deliver the low loss power conversion essential to emerging AI and next-generation industrial applications,” adding, “The NDQ1300 and NDQ1600 deliver high power density and high efficiency across the range, offer a standard footprint to optimize performance, reduce power use and size, and simplify design.”
