ITECH IT7915P-350-90 Regenerative Grid Simulator

Overview

The ITECH IT7915P-350-90 is a 15 kVA high-performance regenerative grid simulator from the IT7900P series. Utilizing advanced SiC (silicon carbide) technology, it provides an all-in-one solution for power testing with the ability to function as a regenerative grid simulator, four-quadrant power amplifier, and four-quadrant AC/DC electronic load. The compact modular design achieves 15 kVA in 3U form factor with regenerative capability to feed power back to the grid, reducing operational costs and heat dissipation.
