Austin Tseng, President of Delta Electronics (Americas), said, “AI is driving a new wave of technological transformation across global industries. By proactively developing 800 VDC and ±400 VDC high-voltage architectures, along with advanced liquid cooling and networking technologies, Delta aims to provide integrated solutions that help customers build AI data centers combining high performance with long-term sustainability.”

Key highlights of the showcase include Delta’s next-generation comprehensive power solutions supporting both 800 VDC and ±400 VDC architectures, purpose-built for high-density, megawatt-scale AI data centers. In the 800 VDC architecture, the Solid-State Transformer (SST) converts medium-voltage AC to 800 VDC with up to 98.5% energy conversion efficiency. The solution also features a 1 MW In-Row Power System and an Energy Variance Appliance (EVA) Rack, which leverage energy storage and capacitance systems to smooth GPU peak loads, achieving up to 97% efficiency at full load. For ±400 VDC architectures, Delta provides an In-Row Power System with active current control, 72 kW rack-mounted power shelves, and high-efficiency Battery Backup Units (BBU) designed for seamless integration with existing ORV3 racks.

In thermal management, Delta introduced a 2,000 kW Liquid-to-Liquid (L2L) Coolant Distribution Unit (CDU) and a new 300 kW Liquid-to-Air (L2A) CDU, addressing the cooling requirements of both new and existing data centers. Complementing these are high-efficiency cold plates optimized for the latest AI chip designs, as well as 4U and 6U rack-mounted CDUs with 140 kW and 250 kW cooling capacities, respectively—forming a comprehensive liquid cooling solution portfolio.

In networking, Delta showcased its next-generation 1.6T Ethernet Switch, featuring 224G-per-lane signaling and ultra-low latency, serving as a critical enabler for high-speed connectivity across AI servers and data centers.The new Delta x Google 2MW liquid-to-liquid CDU was a key highlight at the booth.

Through the integration of its core competencies in power electronics, thermal management, and networking technologies, Delta continues to advance AI data centers toward high-performance and low-carbon operations, laying a solid and sustainable foundation for the global AI ecosystem.
