AI data centers are getting denser, hungrier for power, and harder to cool, and Delta Electronics is bringing a pretty comprehensive answer to the problem at Data Center World (DCW) Asia 2026, as it showcased its new AI Modular Data Center (AI MDC) alongside microgrid solutions designed to help data center operators deploy AI infrastructure faster while improving power efficiency and resilience.
One of the main technologies on display is Delta’s 800 VDC In-Row Power system, which delivers up to 660kW of output power with claimed AC-DC efficiency of up to 98%. The system also supports up to 480kW of battery backup capacity, while aluminium capacitors are used to help optimize power delivery for GPU workloads.
For cooling, Delta is showcasing its high-voltage direct current (HVDC) 3.6MW in-row coolant distribution unit (CDU), designed to handle the thermal demands of high-density AI workloads. At the board level, the company also has a dedicated cold plate for the NVIDIA Vera Rubin NVL72, using a microchannel and multi-impinging flow design to improve thermal management.
Delta is also demonstrating its prefabricated AI Containerized Data Center (CDC) solutions. The systems can deliver up to 60kW per rack of AI compute within a footprint roughly equivalent to a single parking space, while an integrated Liquid-to-Air CDU system can achieve a power usage effectiveness (PUE) as low as 1.19. That modular approach is particularly relevant as operators look to add AI capacity without waiting for an entire conventional data center build-out.
Meanwhile, the Microgrid Solution combines renewable energy generation, energy storage, Solid Oxide Fuel Cell (SOFC) systems, and power conversion technologies with a new Solid State Transformer (SST). The SST is designed to directly convert medium-voltage power to 800 VDC, matching the power architecture being developed for future AI factories.
The system can coordinate multiple energy sources in real time to maintain uptime and power quality during grid connection delays or off-grid operation. Delta says its SOFC system can provide continuous on-site power, while the prefabricated DC-coupled architecture combines SSTs, DC/DC converters, and dynamic energy support. By reducing the number of power conversion stages, the architecture is designed to respond more efficiently to fluctuating AI workloads while allowing operators to scale the system as their infrastructure grows.
