The Chroma 61800 series of 3U-high regenerative grid simulators offers three models with power ratings of 9kVA, 12kVA, and 15kVA, and includes single-phase and three-phase operation. With output voltage ranges up to 350V and 606V, each model can achieve 700V with a single-phase 3-wire setup. Users can increase output power by configuring up to three units in parallel. The Chroma 61809/61812/61815 models are regenerative, providing a complete energy-saving solution. The power generated by the DUT during the test can be efficiently fed back to the grid, rather than dissipated as heat, which protects the environment and lowers the cost of operation.
