PRL High-Dynamic Programmable Regenerative DC Load

Unprecedented Innovation with High-Dynamics and Regenerative Load Accommodated in One System

PRL breaks the technical boundary between ultra-fast dynamic tracking of traditional linear loads and the energy efficiency of switch-mode regenerative architectures.

The unified platform solves the ultimate contradiction for AI data center validation. During standard operations, PRL delivers a measured peak energy regeneration efficiency of up to 85%. Respectively, even under rigorous 1kHz high-frequency dynamic full-load step testing, the system consistently maintains an unmatched regenerative efficiency of >70.34%. PRL is an unprecedented testing platform that integrate the advantages of reducing facility heat dissipation and utility costs and the sustainability with testing intensity uncompromised into one platform.

Dual Voltage Platform and Versatile Testing Applications for both Prevailing and Future-Proof AI Data Center Architecture

PRL Programmable Regenerative DC Load functions with two voltage rating platforms for emulating AI server load profiles in alignment with end-to-end validation ecosystem and the full spectrum of data center power delivery networks (PDN) in AI data center industry.

• 80V Platform: PRL with 80V power rating targets the testing application of back-end computing power nodes by simulating the microsecond-level transients of 50V/54V Power Shelves, OAM modules, and localized CPU/GPU workloads.
• 1000V High-Voltage Platform: High-voltage variant of PRL DC load applies for the facility distribution front-end for validating future-proof testing and next-generation Solid-State Transformers (SST) and mainstream High-Voltage DC (800V/400V) architectures.

High-Dynamic Performances, Ultra-Fast Slew Rate and Low Overshoot, and Robust Overload Capability

PRL features a ultra-fast slew rate of up to 60A/μs with microsecond-level response times (≤6μs) which outperforms the OCP ORV3 industry standard (6 A/μs) by a staggering factor of ten.

A low-current overshoot profile is meanwhile sustained below 3% even at such an ultimate high speed that safeguards high-fidelity waveform emulation without distorting the device under test.

Furthermore, the system boasts a robust continuous overload capability of up to 1.6 times the rated current for a duration of 2 milliseconds, which aligns with the shifting and volatile instantaneous peak pulse currents generated by modern AI computing.

High-Frequency Dynamic Sampling and High-Speed Load Condition Emulation in Alignment with Shifting AI Server Operation Profile

Excellent sampling capability and load emulation resolution with high-frequency of 500kH of PRL supports accurate and realistic reproduction of voltage and current profiles that aligns with real-world power switching noise and pulse charge/discharge characteristics in AI data center. PRL is further capable of operating at high-speed dynamic mode with load switching frequencies up to 30 kHz supported for perfectly emulates the shifting, unpredictable power draw profiles of AI servers.

Modular Scalability with High-Power Density and Compact Footprint

ActionPower India redefines spatial efficiency by packing rated powers of up to 18.5 kW (80V version) and 25 kW (1000V version) into a highly compact 5U standard chassis weighing merely 65 kg.

Utilizing this 5U module as a core building block, the system offers exceptional cabinet-level parallel scalability. By parallelling up to 7 units, a single cabinet can seamlessly achieve a massive 175 kW power rating within a minimal footprint of just 800 × 1000 × 1955 mm. Further and thanks to the parallel connection technologies of ActionPower India, the modular expansion guarantees zero performance loss by maintaining its microsecond-level dynamic response entirely intact at any power scale.

Built-in Testing Automation Sequences in Compliance with EDPP and OCP/OPP requirements along with User-Defined Sequences

PRL streamlines the validation workflow and reduces engineering overhead with comprehensive built-in testing automation. The integrated interface natively offers standard testing recipes of EDPP (Electrical Design Power Profile) testing with direct compliance validation against modern server power specifications.

Additionally, the system features automated testing protocols for OCP (Over Current Protection) and OPP (Over Power Protection), alongside dynamic scanning capabilities. For highly specialized test cases, engineers can leverage advanced Sequence Programming to build custom, user-defined load profiles via the intuitive interface or standard SCPI communication protocols.
