Delta unveils AI modular data centre for NVIDIA Vera Rubin

Delta Electronics has unveiled an AI modular data centre with an 800 VDC in-row power system built for NVIDIA Vera Rubin. It also presented a microgrid system for powering AI data centres in Southeast Asia.

The modular system combines prefabricated data centre infrastructure with liquid cooling and a direct current power architecture for high-density AI computing deployments.

Delta said the AI Modular Data Centre integrates an 800 VDC in-row power design with liquid cooling to support installations based on NVIDIA Vera Rubin architecture. The system is intended to speed deployment and expansion as operators in the region face rising demand for computing capacity.

Delta disclosed several technical details of the power setup. The 800 VDC in-row architecture delivers 660kW of output power, up to 98% AC-DC efficiency and 480kW of battery backup capacity. It also uses aluminium capacitors in a design intended to support GPU workloads in next-generation AI data centres.

Alongside the modular data centre, Delta outlined its approach to energy supply for AI facilities through a separate microgrid offering. The system combines renewable energy, energy storage, solid oxide fuel cell systems and solid state transformers.

According to the company, the solid state transformer is designed to convert medium-voltage electricity directly to 800 VDC. The microgrid system can coordinate multiple energy sources in real time to maintain uptime and power quality during grid connection delays or off-grid operation, while the fuel cell system provides around-the-clock on-site power.

The microgrid design uses a prefabricated DC-coupled architecture that combines solid state transformers, DC/DC converters and dynamic energy support. Delta said this reduces conversion stages and allows the system to respond to fluctuating AI loads while supporting larger deployments.

Regional demand

The launch comes as Singapore and the wider Southeast Asia market attract growing investment in AI infrastructure. Data centre operators across the region are under pressure to add capacity quickly and accommodate much higher rack densities than in previous deployment cycles.

Delta is positioning its offering around that shift, combining electrical infrastructure, cooling systems and on-site power resources in a single package. The company also highlighted a prefabricated AI containerised data centre product that can deliver up to 60kW per rack of AI compute within the footprint of a single parking space.

The containerised design also includes an integrated liquid-to-air coolant distribution unit system. Delta said it can achieve a power usage effectiveness rating as low as 1.19.

At board level, the company also disclosed a thermal management product designed for NVIDIA Vera Rubin NVL72. It said the cold plate uses a microchannel and multi-impinging flow design.

The broader push reflects a change in how suppliers to the data centre sector are framing AI infrastructure projects. Rather than focusing only on servers and racks, vendors are increasingly presenting complete systems that combine power conversion, battery backup, thermal management and on-site generation.

That trend is particularly visible in AI deployments, where high-density clusters create heavier and less predictable electricity and cooling loads. In Southeast Asia, those pressures are colliding with grid constraints, land limits and rising scrutiny over the energy use of digital infrastructure.

Jason Yuan, President, Southeast Asia & ANZ, Delta Electronics, said the demands created by AI are forcing a rethink in infrastructure planning.

"AI workloads are scaling faster than most data centres were designed to handle, while their demands can be increasingly unpredictable. This means infrastructure planning must move from reactive to integrated and future-ready," said Jason Yuan, President, Southeast Asia & ANZ, Delta Electronics.

He added: "Our AI Modular Data Centres and Microgrids, both part of our Grid-to-Chip Solutions portfolio, are ideal to help our clients across Southeast Asia deploy and power their future-ready AI data centers. Moreover, Delta's solutions are engineered for energy efficiency, reliability and performance, while providing the flexibility to adapt to changing workloads and infrastructure demands."
