Product Information "Regenerative High Voltage Grid Simulator | IT7900H Series"
ITECH IT7900H Series
Regenerative High-Voltage Grid Simulator
100% Current Absorption/Regeneration, up to 1050 V L-N (700 V L-N), up to 900 kVA in Parallel Operation
The IT7900H Series is a regenerative, programmable four-quadrant grid simulator that can also be used as a power amplifier for testing all types of grid-connected products. With energy-saving regeneration, the units support a wide range of applications.
Examples include PCS, energy storage systems, microgrids, BOBC (V2X), and power hardware-in-the-loop simulation (PHiL).
The IT7900H Series offers two variants with 700 V L-N (1200 V L-L) or 1050 V L-N (1818 V L-L). Power can be expanded up to 900 kVA via parallel operation.
In addition to a touchscreen with a clear UI, the series provides arbitrary waveform editing functions to simulate a wide range of grid disturbances.
