IT7905-350-30U

ITECH - IT7905-350-30U

The IT7900 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 the islanding mode (RLC settable), a single unit of IT7900 can realize the anti-islanding protection test. Besides, the power density of IT7900 series is very high, 15kVA in 3U. After parallel connection, the power can be extended to 960kVA at most.
