The IT7900E High Voltage Series is designed for high-power applications, capable of handling voltages up to 1050 VL-N and power up to 126 kVA per unit. The unit is equipped with regenerative energy recovery, which helps to feed back the generated power to the grid, reducing electricity costs and the need for cooling systems.

The master-slave parallel operation feature allows users to scale the system's power up to 900 kVA without compromising performance or accuracy. The unit offers AC, DC, and AC+DC output modes and supports three-phase output for comprehensive testing of grid-connected systems.

With its built-in oscilloscope, users can conduct real-time analysis of voltage, current, and phase relationships with the ability to trigger waveforms and display up to 6 oscilloscope curves simultaneously. The harmonic simulation functionality enables users to simulate power grid disturbances such as voltage sags, frequency variations, and phase jumps.
