California Instruments Sequoia Series | Regenerative AC Grid Simulator

The California Instruments Sequoia Series is a programmable regenerative grid simulator designed for advanced AC and DC power testing applications. It operates with a frequency range of 16 Hz to 1,000 Hz, offers power outputs from 15 kVA to 90 kVa, and supports dual voltage ranges of 0–166 V and 0–333 V line-to-neutral, with optional ranges up to 715 V. Featuring advanced waveform generation, high-speed transient simulations, and regenerative energy recovery the Sequoia is ideal for renewable energy testing, power compliance, avionics, shipboard systems, and R&D environments. The Sequoia Series complies with international standards for power quality and grid simulation, making it suitable for testing equipment under various conditions.
