ABB launches Infinitus DC power portfolio for AI data centers

ABB has introduced Infinitus, a portfolio of DC power solutions for AI data centers. The offering is built around ABB’s Infinitus solid-state transformer and includes medium-voltage power systems intended to provide resilient supply from either the grid or local generation.

The company describes Infinitus as an integrated, source-to-rack DC portfolio for facilities moving toward native DC or hybrid AC/DC electrical architectures. ABB says 800 V DC distribution can remove redundant power-conversion stages found in conventional AC systems, reduce associated heat losses and support a more compact power-infrastructure footprint.

The proposition is aimed at the growing power-density challenge in AI infrastructure. The source cites expected next-generation AI-chip demand of 1 MW per rack and beyond, compared with almost 200 kW per rack today. At those densities, conversion losses, thermal management and the physical space required by electrical equipment become material constraints on usable IT capacity.

ABB estimates that 25% to 40% of new data-center capacity installed in 2030 could use DC distribution. A BCG/ABB calculation cited by the company puts the energy-efficiency gain from DC distribution at more than 5%. As an illustrative—not project-specific—case, ABB states that a 5% efficiency gain at a 500 MW data center could make 25 MW available for revenue-generating IT loads and support more than $300 million in additional annual revenue.

The launch intensifies supplier competition around high-density AI data-center power infrastructure. If the performance and economics of DC architectures are demonstrated in operating deployments, operators of large campuses may view DC distribution not only as a specialist power topology, but as a potential means to shift a greater share of available electrical capacity to IT equipment while reducing the footprint of power systems.
