With increasing AI workload demands leading to higher rack densities, data centers are quickly embracing high-voltage DC power systems to enhance efficiency and accommodate evolving infrastructure. Nevertheless, this transition brings forth new difficulties in terms of anchorage, safeguarding, security, and adherence to legal requirements.
The Open Compute Project (OCP) Sidecar architecture is aiding in the reformation of power supply via 800V DC and ±400V DC configurations. It is crucial to comprehend the compromises between these methods in order to create robust, scalable energy networks that optimize availability and safeguard vital infrastructure.
This ABB publication delves into earthing techniques, evaluates DC distribution configurations, summarizes fundamental UL and NEC specifications, and offers hands-on advice for deploying secure, forward-looking power security measures for AI-based data centers.
