As AI data centers transition from traditional UPS-backed architectures toward next-generation HVDC and SST infrastructures to optimize Power Usage Effectiveness (PUE), they face a critical challenge: the shifting, volatile, and highly unpredictable power draw of modern AI servers. Along with the rapid technological evolution, rigorous testing and validation of every power node and component within the architecture is no longer negotiable.
ActionPower is proud to announce the launch of PRL Series DC Load Simulator – a high-dynamic regenerative DC load simulator purpose-built to tackle the most demanding testing environments of next-generation AI data centers.
Breaking the Boundary of Linear and Switch-Mode Programmable Load: What to Expect with PRL?
Despite the technical consensus that high dynamics and regenerative capabilities are topologically incompatible in programmable loads, the PRL unprecedentedly overcomes the differences by combining the advantages of both linear and switching architectures into a single, compact 5U and cabinet-scalable platform.
PRL DC Load Simulator accommodates ultra-fast dynamic response and microsecond-level slew rates while combining the testing sustainability of switch-mode load architecture with regenerative efficiency of over 85% for minimizing head stress. The technical challenges once faced in AI data center power testing and load simulation are now a thing of the past.
Extreme Dynamics & High-Precision Tracking
PRL operates with microsecond-level current response times of as low as ≤6μs and a peak current slew rate of up to 60 A/μs – exceeding OCP ORV3 standard requirements tenfold. While pursuing ultimate speed, the system demonstrates exceptional low-overshoot control. Even under extreme high-slew-rate dynamic testing, current overshoot is strictly maintained at <2.5% without impacting the power supply under test.
High-Efficiency Regeneration Accommodated along with High Dynamics
PRL, when operating at rated conditions, achieves a peak energy regeneration efficiency of 87.1% with a grid-side power factor of PF ≥ 0.99. Even when optionally conducting power testing under 1kHz high-frequency dynamic full-load mode – traditionally recognized as the most challenging scenario for energy recovery – PRL still sustains an impressive measured regeneration efficiency of >70.35%. With PRL applied for load emulation testing, AI date center considerably reduces laboratory heat dissipation, HVAC energy consumption, and overall utility bills.
High Power Density & Transient Overload Capability
The PRL’s 5U form factor chassis reaches power ratings of 18.5 kW and 25 kW for its 80V and 1000V platforms, respectively, while maintaining a total weight of less than 65 kg. The system supports a maximum transient continuous overload capability of up to 1.6x for a duration of 2ms, which perfectly aligns with the shifting and dramatic volatility of AI servers’ peak current spikes.
Modular Parallel Scalability
PRL supports various cabinet-upscaling options through parallel connection by integrated up to 7 modular units into a standard cabinet system with space-efficient dimensions of just 800 × 1000 × 1955 mm while achieving a massive 175 kW power capacity. ActionPower’s parallel connection technology maintains the system’s microsecond-level dynamic response and highly efficient regeneration capabilities, with testing precision intact at any testing scenarios.
