ITECH Electronics has introduced the IT7900 regenerative grid simulator, a programmable grid simulator and 4-quadrant AC source.
The IT7900, which is designed to test grid-tied inverters, includes a built-in RLC anti-islanding load, a grid simulator and a power meter in one unit. Users can configure parameters such as RLC, active power and reactive power of each phase to simulate linear and non-linear grid loading. The built-in power meter can measure harmonics, power factor, crest factor and more.
The unit features power outputs from 5 kVA to 960 kVA. The company says the IT7900 is power-regenerative—about 90% of the power generated by DUTs can be fed back to the AC grid.
