Our showcase at this year’s GTC demonstrates innovative power and cooling solutions for AI data centers, quite a few of which were designed with NVIDIA for their next-generation GPU architecture, as well as a smart manufacturing demo line integrated with AI technologies. Moreover, our D-Bot cobot, power and cooling solutions for the NVIDIA MGX platform are also being featured. This comprehensive solutions portfolio for both cloud data centers and edge applications is a testament to Delta’s unique innovation prowess in the AI era.”
Key highlights at the Delta booth #1023 at NVIDIA GTC 2025 include:
AI-based Smart Manufacturing Demo Line
Delta has leveraged its unique smart manufacturing expertise and system integration capabilities to develop 5 smart production scenarios of PC boards assembly, which visitors will have the opportunity to interact with on-site. The AI-based Smart Manufacturing Demo Line features an ecosystem in which Delta’s D-Bot series Collaborative Robots (cobots), Omni® inserter, Integra® modular glue dispensing machine, DIATwin digital twin system, and IIoT-based Line Manager platform, collaborate along with NVIDIA Omniverse and Isaac Sim to enable cyber-physical production with virtual reality synchronization, virtual commissioning and product parameter input, smart production recipe generation and management, automated production line changeover, automated collision avoidance, and more.
The IIoT-based Line Manager enables remote control, autonomous production line operations, and data analytics. By uploading product recipe parameters to Line Manager, manufacturers can quickly changeover between different product manufacturing processes while dynamically optimizing process parameters such as processing route and speed, achieving seamless automated mixed-model production.
Power Solutions for AI and HPC Data Centers
Delta is launching a new Power Capacitance Shelf at GTC. Designed to ensure a stable power supply for AI and cloud computing servers, this system boasts built-in lithium-ion capacitors (LIC), high power density and long hold-up time (5-second/15kW load) to perform fast charge / discharge so as to mitigate the GPU dynamic load reflections (AI server EDPP and idle mode transitions) to the AC electricity grid. In addition, the new 19-inch 1RU 66kW AC-DC Server Power Shelf offers industry-leading efficiency up to 97.5%.
In traditional AI data centers, AI servers commonly occupy up to 3/4 of rack space, leaving limited room for power supply, backup power, and power capacitance systems. Delta’s new HVDC server power solution, designed through collaboration with NVIDIA, helps IT managers solve that challenge by offering groundbreaking power supply capacities. The solution includes the newly-developed 72kW AC-DC Server Power Shelf to convert 400-480Vac from the transformer to 800Vdc with efficiency up to 98% while the new 90kW DC-DC Server Power Shelf converts 800Vdc to 50Vdc with efficiency as high as 98.5%. Lastly, Delta is also showcasing new parallel HVDC Modules for 800Vdc to 50/12Vdc power conversion and with power density up to 2,500W/inch3.
The industry’s first ORV3 Inverter Power System for 2.5kVA/230Vac, and the new 2RU compact 22kW Battery Backup System to support 48Vdc systems with up to 60 seconds of backup time and surge load capability, are also featured.
The Delta-designed rack for the NVIDIA MGX platform, offers a 1,400A busbar as well as 42RU manifold, is also exhibited along with key Delta solutions, such as management switches, server cooling solutions, 1RU inverter shelves, 1RU 55kW power shelves (3 phase), 72kW HVDC power shelves and 90kW DC-DC power shelves, 19’’ power capacitance systems, 2RU 22kW Battery Backup Power, and 4RU L2L CDUs.
Liquid and Air Cooling Solutions for AI Data Centers and GPU Systems
The newly-launched 1.5MW L2L (liquid-to-liquid) CDU, approved into the privileged NVIDIA RVL and AVL lists, is specifically designed to handle the thermal management challenges of multiple high-density racks, which can exceed 100kW capacity each. Delta’s liquid cooling solutions showcase also includes Cold Plate Loops, designed for the latest NVIDIA GPU/CPU to operate in conjunction with Delta’s 4RU L2L In-Rack CDUs for NVL72/36 as a complete rack scale cooling solution, as well as the powerful new 6RU in-rack CDU design with 200kW cooling capacity for next-generation chips. Also featured are cutting-edge air cooling options, including the new 3D Vapor Chamber boasting 1000W cooling capacity in a 4RU form factor, server fan achieving 20% performance increase versus prior models, and new rack fans capable of supporting different rack power architectures including HVDC (400-800Vdc).
Passive Components for AI and HPC Data Centers
Delta’s new High Density Power Chokes (dual/quad) support GPU operations under high current, high temperature (up to 150oC) conditions. For power and IT shelves operating in high current (4000-8000A), high voltage (+/-400V), high frequency (10-100MHz) conditions, the newly-launched Core Shell Liquid Cooling Busbars offer power dissipation up to 400kW with ultra-low inductance and superior performance.
Welcome to Delta’s booth #1023 at NVIDIA GTC 2025 to learn how Delta and NVIDIA collaborate to usher a new era of AI-based smart manufacturing and energy conservation in the AI realm.
