Product Information "Regenerative grid simulator | IT7900 Series"
ITECH IT7900 Series
Programmable Regenerative Four-Quadrant Grid Simulator
Power: Up to 165 kVA, Voltage: 350 V, Current: Up to 990 A
The IT7900 Series represents the latest generation of programmable four-quadrant grid simulators and can be used to test a wide range of grid-tied devices.
Advanced SiC semiconductor technology delivers high power density in a compact footprint.
The series provides 6 kVA in a 1U chassis. In master/slave parallel operation, output power scales up to 960 kVA.
Multiple operating modes support diverse test requirements, including single-phase, three-phase, anti-phase, and multi-channel operation.
In addition to supplying sensitive applications with precise AC power, the IT7900 Series can simulate distorted voltage waveforms, disturbance signals, and grid faults.
