The IT7900E series is a programmable, four-quadrant grid simulator
It is also a four-quadrant power amplifier, which can be used to test various grid-connected equipment.
For example, PCS, energy storage system, microgrid, BOBC (V2X), PHiL, etc.
With advanced SiC technolgoy, a single unit of IT7900E can realize the anti-islanding protection test through islanding mode(RLC settable).
Besides, the power density of IT7900E series is very high, 6kVA in 1U, 15kVA in 3U. After parallel connection, the power can be extended to 960kVA at most.
Rich operating modes meet various test requirements of single-phase, three-phase, reverse-phase and multi-channel.
In reverse mode, the voltage can be extended to 200% of the rated voltage.
The strong arbitrary waveform editing function can simulate various power grid disturbance waveforms, making it an ideal choice for testing and R&D laboratories.
