Agilent/Keysight SL1820A

The Agilent/Keysight SL1820A is a regenerative DC emulator engineered for high-power testing of EV battery systems and EVSE equipment. This SiC-based instrument delivers 90 kW base power with expandable configurations up to 180 kW or 270 kW, and supports system paralleling to 1.5 MW. It operates bidirectionally, sourcing power to simulate battery behavior during charging and sinking regenerative energy back to the grid, delivering 96% efficiency in both modes while reducing operational cooling costs.
