Power testing solutions include our new 63202A-20 Ultra-Low Voltage DC Electronic Loads, which simulates real-world power conditions for the design, testing, and validation of point-of-load converters (POLs), embedded DC-DC converters, and voltage regulator modules (VRMs). Other instruments include our 61800 Grid Simulators to ensure AI servers can withstand varying power inputs and disturbances, while our programmable DC Power Supplies provide power to the VRM’s and POL converters for voltage regulation testing.

With AI applications requiring constant uptime and peak efficiency, ensuring power integrity and reliability is paramount. Chroma provides engineers the ability to increase inefficiency, optimize performance, and meet strict regulatory standards. Whether you’re designing complete AI power systems for data centers or boundary testing components, Chroma provides indispensable tools to pave the way for faster, more efficient AI servers.

AI server power testing involves evaluating the power supply systems’ performance, efficiency, and reliability that support these high-demand computing environments. Here are some key aspects:

  1. Power Supply Efficiency: Ensuring that the power supply units (PSUs) meet high-efficiency levels across various load ranges.

  2. Power Integrity Testing: Assessing the quality of power delivered to the AI server components, including measuring voltage and current at the Point of Load (POL) to ensure they meet specifications under all operating conditions.

  3. Thermal Management: Evaluating how effectively the power systems manage heat is crucial for maintaining performance and preventing overheating.

  4. Load Testing: Simulating real-world conditions to test how the power systems handle peak demands and ensure they can sustain performance without failure.

  5. Regulatory Compliance: Adhering to industry standards and regulations, such as those set by IEEE and IEC, to ensure safety and reliability.

100kW AI Server Architecture

The image illustrates a typical 100kW AI server featuring a server cabinet with a water-cooled system and a 48V backplane. The server cabinet houses 10 server cards, each containing 10 AI chips, totaling 100 AI chips consuming 10kW. The power supply system includes a 480V 3-phase 100kW input, which is simulated by a Chroma 61800 grid simulator. The power is then managed by a regenerative DC electronic load (Chroma 63700) and distributed through high power DC electronic loads (Chroma 63200A) and high-power DC power supplies (Chroma 62000DC). Voltage regulation is achieved using a 48V to 12V voltage regulator and a 12V to 0.8V POL converter tested by ultra-low voltage DC electronic loads (Chroma 63202A-20-2000) and programmable DC power supplies (Chroma 62000P).

Server Cabinet Power Verification Testing Setup

The image illustrates a Server Cabinet Thermal & Power Verification Testing setup. It shows a facility requirement 8kW at 480V 3-phase power connected to a 100kW Grid Simulator (Chroma 61800). This simulator is linked to a 100kW AI Server Cabinet, which operates at 48VDC. The server cabinet is connected to a 100kW Regen Load (Chroma 63700). The process demonstrates a 92% regeneration efficiency. The diagram depicts the power flow from the facility to the grid simulator, then to the server cabinet, and finally to the regen load. The setup is relevant for testing server cabinets’ thermal and power performance, ensuring they meet specific standards and operate efficiently.
