In AI workloads, instantaneous power surges demand uncompromised reliability, as any brief drop in power can undermine GPU computation. To address this demand, Chroma developed the 62450D-2000HL, a bidirectional DC power supply and regenerative electronic load purpose-engineered for high-voltage, high-power testing.
Whether it’s a power supply unit (PSU) rated at tens of kilowatts, a power shelf at hundreds of kilowatts, or a power rack reaching megawatt levels, all must meet stringent transient response and current slew rate requirements. Chroma 63200A DC Electronic Load series offers single-unit power ratings from 2kW to 24kW, and supports synchronous dynamic operation of up to 60 units for a maximum rated power of 1.44MW.
With the discontinuation of NH Research (NHR) 9300 systems, many labs are seeking a replacement that delivers higher flexibility, better performance, and modern integration. Chroma’s 62000D regenerative DC power systems offer a clear upgrade—combining compact modular design, advanced control, and industry certifications that ensure long-term dependability.
With the rapid expansion of AI application scenarios, the floating-point operations per second (FLOPS) of large language models (LLMs) surpassed 1025 by the end of 2024. The power demand from high-density integrated AI GPUs used in training and inference continues to climb.
Chroma’s 62450D-2000HL Bidirectional DC Power Supply is designed with high power density, delivering up to 45kW output in a compact 4U chassis. With master-slave parallel configuration, it can deliver up to 360kW in a standard 41U 19-inch rack, and scale even further to MW-level output through cross-cabinet parallel connection.
Choosing the right programmable AC power source is critical to the success of your test strategy. From simulating global voltage/frequency standards to replicating grid disturbances, the right source gives you the control to test smarter, faster, and with more confidence. The wrong choice can limit your flexibility, slow down production, or even miss critical failures.
Most ITIC test conditions (i.e. the yellow and green zones on the curve) are easy to achieve with Chroma test equipment. The 500% voltage surge test in the red zone poses a more significant challenge. To help users accelerate product development and validation, we conducted simulations using 105kVA Chroma 61800-100 Grid Simulators.
Chroma’s PowerPro 5 software, part of its comprehensive EV test system solution, features a Certificate Management Tool that allows users to load specific certificate files (*.p12, *.pem). Using designated OEM agreements and contract certificates, the software automatically performs public/private key encryption and decryption during the test to achieve the handshake and payment processes required for ISO 15118 PnC testing.
