California Instruments Sequoia SQ0090 Regenerative AC Grid Simulator

The California Instruments Sequoia SQ0090 is a regenerative AC grid simulator with 90 kVA/90 kW three-phase output, supporting AC, DC, and AC+DC modes as well as regenerative sink and optional electronic load operation. It offers dual AC voltage ranges (0–166 Vrms and 0–333 Vrms line-to-neutral), DC output up to 440 V, and frequency range from DC to 550 Hz (up to 905 Hz with option). The system features 250 Arms maximum current per phase, 85% typical efficiency, remote control interfaces, and built-in harmonic analysis. It is designed for grid simulation, renewable energy, compliance, and automated test applications.
