Ultra-Low Voltage DC Load 0.25V@2000A - Suitable for CPU & GPU VCORE Power Supply Test
Generative AI is developing at a rapid pace, showcasing increasingly impressive capabilities in diverse areas from voice and image generation to medical imaging. As these technologies require massive amounts of complex and real-time computation, the servers delivering them must be equipped with high-performance central processing units (CPUs) and graphics processing units (GPUs). For power, these processors require VCORE regulators, embedded DC-DC converters, or voltage regulator modules (VRM). Their voltage output range is approximately 0.6V to 1.5V, with VCORE current ranging between 300A and 800A. Current ranges for GPU power supply are typically 800A to 1400A, continuing to trend towards higher currents and power. To validate these low-voltage power supplies, engineers typically employ electronic loads to simulate their load characteristics and test high-current output specifications. Conventional electronic loads, however, frequently struggle to handle issues such as insufficient voltage for proper current draw, or difficulty connecting to the unit under test (UUT) due to inadequate terminal contacts.
Enter the Chroma 63202A-20-2000, Chroma's new ultra-low voltage DC electronic load specifically designed to facilitate highly accurate and convenient CPU and GPU power supply test. This state-of-the-art DC load operates within a voltage range of 0-20V, with a rated power of 2kW and available in 1,000A and 2,000A models. To accommodate the especially low output voltages of CPU and GPU power supplies, the Chroma 63202A-20-2000 electronic load features a unique design that enables it to draw current up to 2,000A at voltages as low as 0.25V. Even when the voltage drops down into the 0.25V - 0V range, the load retains its ability to draw current—an essential capability for realistic simulation and accurate testing of GPU power supplies.
In addition, the Chroma 63202A-20-2000 features a unique front copper busbar terminal design. Besides facilitating easier connection to the UUT, the left and right busbars are interconnected, with insulating plates added between the positive and negative busbars to prevent short circuits. Multiple locking points are provided for extra convenience and stability. This design enables low-inductance connections, significantly enhancing the load's dynamic response speed and allowing a current slew rate of 60A/us at 0.5V. Chroma also offers optional ultra-low self-inductance load cables that effectively minimize voltage drops or current overshoot during dynamic current testing.
