Kewell A2000: Regenerative AC Grid Simulator with Source and Load Functions
An inverter must operate reliably under more than just stable grid conditions. How does it respond to voltage fluctuations or when feeding power back into the grid? The Kewell A2000 Series enables engineers to test these operating conditions. As a bidirectional AC grid simulator, it supplies the device under test (DUT) with programmable AC power. In regenerative electronic AC load mode, it absorbs power and feeds it back into the utility grid.
For functional and grid compliance testing, the A2000 varies voltage and frequency to simulate voltage dips, grid interruptions, and three-phase voltage unbalance. Programmable voltage profiles, harmonics, and interharmonics allow complex grid disturbances to be reproduced under consistent test conditions.
In load mode, the A2000 simulates different electrical load conditions to assess the DUT's response. The NG 470 V and NG-HV 900 V versions also provide RLC load models. Its modular design and SiC semiconductor technology support a range of power requirements. Choosing between the NG, NG-HV, and PG versions depends on the required voltage range and available functions.
Alternative Products
For a compact AC/DC solution combining source and load functions, consider the Kewell G9000 Series. For lower-power bidirectional AC testing up to 18 kVA, the Kewell G6000 Series is an alternative.
