AI server power supplies are critical components powering high‑power consumption chips such as GPUs. Testing focuses on verifying the stability and efficiency (95–98%) of voltage, current, and temperature, especially under challenges posed by high power (3–10 kW+), 800 V HVDC, and SiC/GaN devices.

   The ART Logics SCU5‑12‑channel high‑speed, high‑voltage data acquisition module stands out in AI server power testing with its ultra‑wide input range (up to 1500 V), high‑isolation safety design, high‑accuracy electro‑thermal dynamic capture (voltage/current sampling rate of 1 ksps, temperature sampling rate of 1 sps), as well as flexible stand‑alone operation (onboard SD card) and automation integration interfaces (C# / LabVIEW API). It effectively supports efficiency calculation, protection‑trigger verification, and long‑term temperature rise evaluation, significantly enhancing test safety and efficiency.
