PPST Solutions adds 800 VDC testing to AI data center portfolio

PPST Solutions expanded its AI data center power testing lineup with the EA-ELR 21000 Dynamic Test System from EA Elektro-Automatik, extending support from AC grid simulation to 800 VDC architectures. The move targets the rising need to validate high-power, high-efficiency power chains for AI data centers as racks and distribution systems move to higher-voltage designs.

Why it matters: - AI data centers are shifting toward higher-voltage DC architectures that need more testing across conversion, distribution, stability and reliability. - The expanded portfolio is built to support testing from the utility grid to AI server racks, including emerging ±400 V and 800 V DC systems. - Regenerative AC and DC test setups can reduce energy use and cooling load during sustained high-power validation.

What happened: - PPST Solutions announced an expansion of its AI data center power testing portfolio with the EA-ELR 21000 Dynamic Test System from EA Elektro-Automatik, a division of Tektronix. - The company made the announcement on Nov. 3, 2026, in Irvine, California. - The portfolio now combines Pacific Power Source AC power sources, grid simulators and regenerative AC loads with EA bidirectional DC power supplies and regenerative DC electronic loads.

The details: - The expanded test coverage spans the full AI data center power chain, from AC utility input and AC-DC conversion to high-voltage DC distribution, 800 V DC systems, power shelves, 48–54V / 12V distribution and AI server racks. - The EA-ELR 21000 Dynamic Test System is designed for high-power, high-dynamic testing of emerging ±400 V and 800 V DC power architectures. - The system uses 30 kW regenerative electronic load modules rated up to 1,000 V and 80 A. - The platform scales to 240 kW per rack and up to 1.92 MW of test capacity. - Pacific Power Source AC RGS Series grid simulators can reproduce programmable voltage, frequency and transient conditions. - Those AC tools can be used for AI server PSU testing, AC-DC rectifier testing, grid disturbances, voltage sag/swell/interruption testing, ITIC curve testing, power quality, efficiency and three-phase conversion testing. - PPST Solutions can pair programmable AC input simulation with DC loading to evaluate input/output performance, conversion efficiency, dynamic load response, regulation, transient response, protection and endurance. - EA bidirectional DC power supplies and regenerative electronic loads support DC-DC converters, power shelves, intermediate bus converters, DC distribution equipment and protection systems. - EA DC test systems support 48–54V rails used close to AI compute hardware for validating high-current stages. - Pacific Power Source AC grid simulators can provide controlled AC input conditions for solid-state transformer and high-power conversion testing, while EA DC sources and regenerative loads exercise the DC side. - EA bidirectional DC power supplies and battery test systems can support battery cycling, battery emulation, BESS validation, backup power testing, dynamic response, efficiency and endurance.

Between the lines: - PPST Solutions is positioning itself around the full AI data center power stack instead of a single test segment. - The combination of AC simulation and regenerative DC testing suggests a push toward more integrated validation for higher-power, more efficient infrastructure. - The collaboration with EA Elektro-Automatik dates to 2018, showing this expansion builds on an existing partnership rather than a one-off product addition.

What's next: - PPST Solutions is directing engineers to speak with an application engineer about AI data center power testing requirements. - The company says it can help teams build test systems for everything from component and power supply validation to rack-level and megawatt-class infrastructure testing. - The expanded offering is likely to matter most as AI infrastructure operators adopt higher-voltage distribution schemes and need broader validation across the power path.

The bottom line: - PPST Solutions is broadening its AI data center testing portfolio to cover the move from AC grid simulation to 800 VDC infrastructure, aiming to support the next generation of high-power AI power systems.
