ITECH IT7900H Series
Regenerative High Voltage Grid Simulator
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. Due to the energy-saving regenerative power supply, the devices have many applications. Examples include PCS, energy storage systems, microgrids, BOBC (V2X) and high-performance hardware loop simulation (PHiL).
The IT7900H series offers two variants with a voltage of 700 V/L-N (1200 V/L-L) or 1050 V/L-N (1818 V/L-L). The output can be extended to 900 kVA through parallel operation.
In addition to a touchscreen with a concise user interface, the series has functions for processing arbitrary signals, which can be used to simulate a wide range of grid faults.
