The CORTEX AC Series (formerly PRE / PRE20 Series) is a rack-mount regenerative 4-quadrant programmable AC power source and grid simulator. A single unit works as an AC/DC source and as an AC/DC (RLC) load with energy regenerated to the grid, for testing grid-tied inverters, on-board chargers, EVSE, aerospace 400 Hz equipment and IEC 61000 immunity.
