Product information "Regenerative Grid Simulator | IT7900E Series"
ITECH IT7900E Series
Programmable, regenerative 4-Quadrant Grid Simulator
Power: up to 231 kVA, Voltage: 350 V, Current: up to 1155 A
The IT7900E series is a programmable four-quadrant grid simulator and power amplifier that can be used to test various grid-connected equipments. The advanced SiC technology provides a high power density of 15 kVA in a 3U unit. When connected in parallel in master/slave mode, the power can be extended up to 1 MVA. Multiple operating modes meet different test requirements from single-phase, three-phase, reverse-phase and multi-channel. With the function for generating arbitrary signals, various waveforms, interference signals and grid disturbance waveforms can be simulated.
Applications of the regenerative grid simulators IT7900E series
- Energy storage systems (ESS)
- Energy conversion systems (PCS)
- Intelligent charging of electric vehicles (BOBC, V2X)
