Pacific Power Source has expanded its AGX, RGS and RLS regenerative AC/DC test platform families with higher power density modules, extended scalability and improved high-frequency load performance. The updated systems are designed for testing EV chargers, V2G equipment, energy storage systems, solar inverters and other high-power electrification hardware.

The expanded platform now features 24 kW per 4U module, scaling to 216 kW per cabinet, 432 kW in parallel cabinet configurations, and three-phase setups up to 1.296 MW. Current capability runs to 48 Arms per phase across 45 Hz to 200 Hz, with new load optimization options for high-frequency testing in load mode.

The three product lines serve different test needs. The AGX is an all-in-one regenerative AC/DC power source that handles sourcing, electronic loading and current source operation in AC, DC, AC+DC and DC+AC modes. The RGS is a grid simulator supporting IEEE 1547.1 and UL 1741 compliance testing for solar inverters, EV chargers, energy storage and distributed energy resources. The RLS is a four-quadrant regenerative load for realistic testing of power conversion equipment, batteries and renewable energy systems.

All three are built on SiC power stages and return more than 90% of absorbed energy back to the facility grid—a significant operating cost reduction when you’re testing 150 kW+ EV chargers or MW-scale storage systems at sustained load. The SmartSource Suite control platform handles test automation, custom waveform generation, compliance testing and real-time measurement through a browser-based interface.

“With up to 24 kW in just 4U and systems scaling to 1.296 MW, customers can achieve higher power levels in a smaller footprint while preserving a common regenerative platform architecture,” said Herman Vaneijkelenburg, Product Director at Pacific Power Source.
