AMETEK California Instruments Sequoia 45 kW AC/DC Regenerative Grid Simulator

Overview

The AMETEK Sequoia 45 kW is a full four-quadrant, fully regenerative AC power source designed to simulate various power line conditions and disturbances. This advanced grid simulator is used for testing solar inverters, online UPSs, Vehicle-to-Grid systems, wind turbine systems, avionics power systems, and power compliance test solutions. The system combines compactness and functionality in a floor-standing chassis with flexible single and three-phase AC or single-channel and multi-channel DC power capabilities.
