Current Stability |
1. When the grid fluctuation is 1%, the three-phase high current generator output current below 500A has a stability of 0.5%FS, i.e., fluctuation within ±5A. When output current is 500A to 800A, stability is 1%FS, i.e., fluctuation within ±10A. When output current is 800A to 6300A, stability is 2%FS, i.e., fluctuation within ±20A. 2. When the grid is stable, the three-phase high current generator output current stability is 0.5%FS, i.e., fluctuation within ±5A. 3. The above current stability is measured after the device has been in use for a period and reached thermal equilibrium. |
