Building Safe, Autonomous Data Centers: How DC800V Powers the Future of Financial Computing

1. Reliability First

Financial data centers must meet the highest reliability, safety, and energy‑efficiency standards. From 2010 to early 2022, 54.2% of financial firms held Uptime Tier IV design certifications, far exceeding other sectors, reflecting strict redundancy and fault‑tolerance requirements. Since late 2022, the share of financial data centers with international Tier certification has dropped because domestic standards now address information‑security concerns and tailor specifications to industry needs, moving from reference‑based to autonomous, finance‑specific standards.

2. Deep Security and Domestic Power

Security boundaries extend from IT to physical infrastructure; in the first half of 2024, over 8,400 financial data‑center data‑leak incidents were reported. Compromised power equipment, cooling systems, or DCIM software can cause server overheating, power mis‑operations, or service outages. The common 2N power architecture is vulnerable if both A and B supply paths rely on the same foreign vendor, as a single security flaw could affect the entire system. Consequently, domestic sourcing of UPS and power‑distribution components is deemed essential, not optional.

Chint (CHINT) has accelerated domesticization, achieving over 99% domestic chip usage and 100% domestically produced core components, covering molds, welding, surface treatment, PCBA, and sheet metal, resulting in more than 100 intellectual‑property assets that reduce supply‑chain risk.

3. AI‑Driven Compute and DC800V Architecture

Unlike internet firms that build massive general‑model training clusters, financial institutions focus on secure, compliant inference, using a “general model + financial enhancement” approach. With the rise of domestic AI chips (e.g., Huawei Ascend) and ultra‑dense AI nodes, cabinet power density has jumped from a few kilowatts to around 100 kW, and 20‑cabinet node clusters can reach 1.6 MW, stressing traditional 400 VAC supplies.

Chint proposes a DC800V supply architecture that converts medium voltage to DC via solid‑state transformers (SST). Its three core benefits are:

Reduced current and line loss, improving efficiency and temperature control.

Lower copper usage, cutting CAPEX and long‑term operating costs.

Support for future high‑power AI cabinets (100 kW+), freeing data‑center space.

DC800V complements, rather than replaces, existing AC systems, providing a high‑efficiency, reliable power solution for next‑generation intelligent computing.

4. Full‑Stack Autonomous Control

Chint showcases its end‑to‑end power‑distribution portfolio, from energy‑side modules to IT‑side solutions (see Table 1). The new generation power module features selectable protection, live‑decoupling, UPS maintenance, and simulation‑driven reliability improvements. Its intelligent monitoring system collects all electrical parameters, key temperatures, and switch states, enabling full‑link visualization and predictive maintenance.

By anchoring on safety, autonomy, and the DC800V architecture, Chint aims to provide commercial banks with a trustworthy, reliable, and controllable power‑infrastructure foundation for the digital, intelligent, and green transformation of finance.
