PPST Solutions, a leading provider of high-power AC and DC power test solutions, announced the expansion of its AI data center power testing portfolio.
IRVINE, CA, UNITED STATES, November 3, 2026 /EINPresswire.com/ — PPST Solutions, a leading provider of high-power AC and DC power test solutions, announced the expansion of its AI data center power testing portfolio with the addition of the EA-ELR 21000 Dynamic Test System from EA Elektro-Automatik, a division of Tektronix.
Building on a collaboration established in 2018, this latest evolution enhances PPST’s ability to support breakthrough innovation in key growth markets—from aerospace and defense, electric vehicles, energy storage and Vehicle-to-Grid (V2G), renewable energy, and AI-driven power infrastructure. The expanded portfolio combines Pacific Power Source AC power sources, grid simulators and regenerative AC loads with EA bidirectional DC power supplies and regenerative DC electronic loads to support testing across the evolving AI data center power architecture—from the AC utility grid and AC-DC power conversion through high-voltage DC distribution, 800 V DC systems, power shelves, 48–54V / 12V distribution and AI server racks.4
As AI computing power requirements continue to increase, data center power architectures are evolving to support higher power density and more efficient power distribution. Emerging ±400 V and 800 V DC architectures create new requirements for validating high-power conversion, distribution, dynamic response, stability and reliability.
“AI data center power is evolving rapidly, and testing needs to evolve with it,” said Peter O’Brien, VP Americas Sales & Marketing at PPST Solutions. “By combining Pacific Power Source AC grid simulation with EA high-power DC sources and regenerative loads, PPST Solutions can support testing across the power conversion chain—from AC grid conditions through high-voltage DC distribution and down to the power levels serving AI compute.”
Testing Across the AI Data Center Power Chain
PPST Solutions offers AI data center test solutions from rack to infrastructure, testing every power conversion component across the power chain.
Regenerative Testing for High-Power AI Infrastructure
Regenerative AC and DC test systems return absorbed energy to the facility or grid rather than dissipating it entirely as heat, reducing energy consumption and cooling burden during sustained high-power testing.
• AC Grid Simulation for AI Data Centers
Pacific Power Source AC RGS Series grid simulators can reproduce programmable voltage, frequency and transient conditions. Applications include 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.
• AC-DC Power Supply Testing
PPST Solutions can combine programmable AC input simulation with DC loading to evaluate input/output performance, conversion efficiency, dynamic load response, regulation, transient response, protection and endurance.
• 800VDC Power Distribution Testing
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. It uses 30 kW regenerative electronic load modules rated up to 1,000 V and 80 A, with systems scalable to 240 kW per rack and up to 1.92 MW of test capacity.
• DC-DC Converter and Power Shelf Testing
EA bidirectional DC power supplies and regenerative electronic loads provide programmable source and load capabilities for DC-DC converters, power shelves, intermediate bus converters, DC distribution equipment and protection systems.
• 48/12V AI Server OCP Rack Power Shelf Testing
48–54V rails remain an important high-current stage closer to AI compute hardware. EA DC test systems provide regenerative loading and bidirectional power capabilities for validating this stage.
• Solid-State Transformer and High-Power Conversion Testing
Pacific Power Source AC grid simulators can provide controlled AC input conditions, while EA DC sources and regenerative loads can exercise the DC side of high-power conversion systems.
• Battery Back-Up (BBU) Power Testing
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.
