At TMetrix, we’re committed to enabling rigorous, flexible, and future‑ready power testing solutions. Our RLS Series Regenerative AC/DC Load Simulator, from Pacific Power Source, delivers on all counts—supporting complex waveform emulation, massive scalability, and energy recovery in a compact footprint that modern test labs demand.
Redefining Electronic Load Simulation
Using cutting‑edge silicon carbide (SiC) power conversion technology, the RLS Series delivers up to 21 kVA/kW in just a 4U rack—one of the highest power densities available today. Multiple units can be paralleled, scaling seamlessly up to 189 kVA/kW per cabinet, or 252 kW with dual‑cabinet configurations—and even beyond in three‑phase systems up to ~756 kW.
But power density is just the beginning. What really sets the RLS apart is its 4‑quadrant AC/DC operation, allowing engineers to simulate both sourcing and sinking of energy, control power factor, and exact power profiles—including harmonics, interharmonics, inrush, and transient conditions—with extreme precision.
Key Features You Can’t Overlook
- Regenerative Efficiency: Returns over 90% of absorbed energy back to the grid, slashing energy loss and facility HVAC costs during extended testing cycles or burn‑in applications.
- Universal AC/DC Support: Handles AC and DC loads across single, split, or three-phase configurations, and even supports simultaneous AC + DC operation per phase or channel.
- Wide Voltage & Frequency Envelope: Operates from 350 VAC line-to-neutral / 606 VAC line-to-line, or ±500 VDC, with frequency coverage from 15 Hz to 1,200 Hz for lab versatility.
- Full Galvanic Isolation: Safeguards the test system and DUT with isolation across inputs, outputs, and between channels.
- Smart Control & Automation: The embedded SmartSource Suite browser interface enables remote control, waveform programming, scope display, and analog/digital I/O integration via LAN, USB, GPIB, or RS‑232.

Where RLS Series Shines
- Electric Vehicle (EV) & Grid‑Tied Power Testing:
Test EV chargers, onboard chargers (OBCs), V2G/V2H systems, EVSE cables, and solar/grid-tied inverters under real-world dynamic load conditions. Simulate grid distortion, inrush currents, or regenerative feedback scenarios with confidence. - Energy Storage & UPS Validation
Characterize battery-powered systems, ESS units, UPS systems, and PDUs in both AC and DC modes. The RLS’s dynamic capabilities support transient discharge tests and compliance validation against IEC and UL standards for energy equipment. - Aerospace & Specialized Power Electronics
With its tight waveform capture, harmonic controls, and broad profile programming, RLS is ideal for testing power converters in aerospace, defense, or industrial applications—simulating extreme or non-linear load events as required.
