Acbel Polytech will showcase high-density power solutions for AI data centers at OCP Global Summit 2026, scheduled for October 13–15 in San Jose, California. Exhibiting alongside subsidiary OmniOn Power, the company will demonstrate power systems supporting ±400V/800V DC and 50V DC architectures, including a 100kW power shelf and a 72kW platform. The announcement reflects growing demand for compact, efficient power conversion as AI accelerators increase electricity requirements at the server and rack levels.
Acbel Targets Rising AI Data Center Power Demands
The expansion of generative AI and accelerator-intensive computing is changing how data center operators design electrical infrastructure. Higher-power GPUs and other accelerators are increasing rack-level power requirements, putting pressure on power conversion efficiency, equipment density, thermal management, and deployment flexibility.
Acbel Polytech is targeting these requirements with a portfolio of high-density power systems that it plans to demonstrate at OCP Global Summit 2026. The company will exhibit alongside its subsidiary OmniOn Power, highlighting technologies for multiple direct-current power architectures used in AI data center infrastructure.
The portfolio includes a 100kW power shelf designed for ±400V/800V DC architectures and a 72kW power shelf for 50V DC systems. Acbel is also developing liquid-cooled power technologies to address the thermal challenges associated with increasingly compact, high-output equipment.
For hyperscale cloud providers, server manufacturers, and data center infrastructure teams, the central challenge is delivering more electrical power within constrained equipment footprints while maintaining reliability and controlling conversion losses.
100kW Power Shelf Supports Flexible DC Architectures
Acbel’s 100kW Power Shelf is designed to deliver 100 kilowatts of output in a compact 1OU form factor, according to the company. Combined with Acbel’s patented power distribution unit (PDU) design, the system can be configured for either ±400V or 800V output, depending on customer requirements.
Higher-voltage DC architectures are attracting attention as AI rack power increases. For a given power level, increasing voltage reduces the current required, potentially lowering resistive losses and easing conductor requirements. The actual benefits depend on the complete electrical design, including conversion stages, distribution components, protection systems, and load characteristics.
Acbel’s configurable approach is intended to support deployments across different DC power architectures rather than locking customers into a single output configuration.
The 1OU specification also highlights the importance of equipment density. By delivering substantial power in a compact shelf, manufacturers aim to preserve space for computing hardware and other supporting infrastructure. However, the announcement does not provide independent efficiency measurements, operating-temperature data, or comparative performance results for the 100kW system.
72kW Platform Targets 50V DC Systems
For 50V DC infrastructure, Acbel will present a 19-inch, 72kW power shelf incorporating 12kW power modules. The company reports power density of up to 102 watts per cubic inch for the modules and says they have achieved 80 PLUS Ruby certification.
High power density allows more conversion capacity to fit within a limited physical volume, but it also increases the importance of thermal design, airflow, serviceability, and component reliability. Certification provides a relevant efficiency reference, although the announcement does not specify the complete test conditions or provide a full efficiency curve for the system.
Supporting both 50V and higher-voltage DC architectures gives Acbel a portfolio aimed at different infrastructure designs as operators evaluate the next generation of AI servers and racks.
For data center architects, the choice of architecture involves more than the power shelf itself. They must also consider server compatibility, rack distribution, electrical protection, redundancy, maintenance procedures, and the implications of integrating new equipment into existing facilities.
Liquid Cooling Enters the Power Infrastructure Equation
Acbel is developing liquid-cooled power technologies to address rising power density and thermal requirements. As power conversion equipment delivers greater output within smaller enclosures, removing heat becomes an increasingly important engineering consideration.
Liquid cooling can transfer heat more effectively than conventional air-based approaches in suitable designs, but performance depends on the cooling architecture, coolant conditions, facility infrastructure, and maintenance requirements.
The company’s announcement did not provide specifications or a commercialization timeline for its liquid-cooled power products. Their development nevertheless points to a broader convergence between electrical engineering and thermal management in AI infrastructure.
This shift is relevant because power systems and cooling equipment must work together. More compact conversion equipment can increase local heat concentration, making thermal design a factor in both performance and reliability.
OCP Summit Highlights the AI Power Ecosystem
Acbel’s participation in OCP Global Summit 2026 reflects its focus on collaboration with cloud service providers, server manufacturers, and other infrastructure partners.
The Open Compute Project ecosystem is important to data center design because open hardware specifications and industry collaboration can help organizations evaluate and integrate infrastructure technologies across suppliers. As AI computing requirements evolve, power delivery has become a key part of discussions about next-generation rack architecture.
Acbel’s latest portfolio addresses the need for greater power density and support for multiple DC configurations. For potential customers, the next step is to evaluate independently validated efficiency, thermal performance, reliability, and interoperability under real-world operating conditions.
The company’s showcase illustrates how power infrastructure suppliers are adapting their products to the physical demands of AI computing, where electricity delivery and heat removal increasingly shape deployment capacity.
