High-power electronic loads have entered the "MW-level era", accelerating the process of domestic testing equipment becoming more high-end

As AI servers surpass the 10-kilowatt level in power consumption and liquid-cooled supercharging stations advance towards the megawatt level, an undeniable reality looms over the industry: traditional testing equipment struggles to meet the rigorous testing demands of scenarios such as GPU power supply and megawatt-level charging facilities. The difficulty of testing does not increase linearly with each doubling of power; instead, it jumps exponentially. This bottleneck is compelling high-power electronic loads to transition from the kilowatt level to the MW level, and it is also quietly unveiling the curtain of high-end domestic testing equipment.

'Driven by both computing power and new energy, MW-level loads have become a rigid demand.'

In the past, a hundred-kilowatt-class electronic load was sufficient to cover most power testing scenarios. However, the explosion of AI computing power has completely changed this landscape. AI server power supplies and GPU power supplies require testing equipment with extremely high dynamic response capabilities - when GPU load changes instantaneously, the power supply voltage drop must be recovered in microseconds, and the response speed of traditional loads simply cannot keep up.

Meanwhile, the construction of megawatt-scale charging facilities is also accelerating. 800V platform models are being launched in a dense manner, and charging piles of 480kW or even 1MW are starting to be installed in highway service areas. A megawatt-scale charging pile consists of multiple modules connected in parallel, with each pile outputting electric current of over 1000A, directly 'breaking down' the measurement range of traditional electronic loads. A testing leader from a leading charging equipment company bluntly stated, 'In the past, a 150V/60A electronic load could cover single module debugging. Now, what needs to be tested is the entire pile after parallel connection, and the measurement range has directly increased tenfold.'. ”

From standalone systems to MW-scale platforms, there has been a comprehensive leap in technical indicators

Facing these pain points, domestic test equipment manufacturers have given a clear response - MW-level electronic loads are no longer just a concept, but have become actual products. In 2026, Adix officially launched the IT8100A/E series of high-speed high-power DC electronic loads. Its system parallel operation capability can reach up to 1.8MW, achieving a power density of 7.2kW in a 3U rack and up to 86.4kW in a 37U cabinet.

The key aspect is dynamic performance. This series supports ultra-high-speed dynamic ramp-up of 150A/μs, capable of accurately simulating rapid current transitions in scenarios such as AI server power supplies and GPU power supplies. In response to the trend of low voltage and high current for AI GPU power supply, a special ultra-low voltage and high current solution of 60V/2400A/6kW is provided. Additionally, the 1.5 times short-term overpower capability effectively copes with instantaneous peak impacts, avoiding over-provisioning equipment for extreme operating conditions.

Another domestic manufacturer, Aikesi Cyber, is also accelerating its layout. Its PRL series of high-dynamic feedback loads has completed the construction of a MW-level AIDC test platform, utilizing a modular cluster parallel architecture. When multiple units are connected in parallel, they can support MW-level computing power cabinets and whole-station high-power power system testing. This series of products also features high dynamic feedback capabilities, with a dynamic response time of up to 5μs and a comprehensive feedback efficiency of over 80%. This effectively addresses the issues of severe heating and high grid capacity requirements associated with traditional consumption-type loads.

The window for domestic substitution has opened, and the testing paradigm is undergoing an upgrade

The breakthrough in MW-scale electronic loads signifies not only an enhancement in power level but also an upgrade in testing paradigm from 'testing electrical appliances' to 'testing energy systems'. Megawatt supercharging piles often interact with energy storage, photovoltaics, and power grids, making V2G (Vehicle-to-Grid) a standard feature. The testing equipment itself must also possess bidirectional capabilities - it can act as a load to absorb energy, as a power source to feed back energy, and also simulate batteries and power grids. This places higher demands on the integration level and data closed-loop capability of the testing system.

In this round of technological iteration, the rapid response of domestic manufacturers has become a highlight. From the five major performance leaps of the ADEKS IT8100A/E series to the MW-level AIDC test platform of the Aikesi Cyber PRL series, domestic test equipment not only matches international giants in power levels, but also forms differentiated advantages in key indicators such as high dynamic response and energy feedback efficiency. As industry observers have said, the core competitiveness of charging module test equipment in the next three years lies not in single-point accuracy, but in system integration and data closed-loop.

The advent of high-power electronic loads entering the MW-level era is not only a result of the push from AI and the new energy industry, but also a landmark milestone marking the progression of domestic testing equipment towards the high-end. In this testing revolution, domestic manufacturers who are the first to secure a technological foothold are poised to occupy a more significant position in the global power electronics testing market.
