RLS Series

The RLS Series is a regenerative 4-quadrant AC and DC electronic load designed to simulate real-world load conditions for testing power generating and conversion equipment. It delivers exceptional power density up to 21kW in a compact 4U chassis with scalability to 252kW, features galvanic isolation between channels, and operates across a wide input voltage range of 350Vac L-N/606Vac L-L or ±500Vdc without requiring range switching. The RLS Series is ideal for testing EV chargers, solar inverters, energy storage systems, UPS products, and aerospace power equipment while returning energy back to the grid for maximum efficiency.
