Current Stability |
I. 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 between 500A and 800A, stability is 1%FS, i.e., fluctuation within ±10A. When output current is between 800A and 6300A, stability is 2%FS, i.e., fluctuation within ±20A. II. When the grid is stable, the output current stability of the Three-Phase High Current Generator is 0.5%FS, i.e., fluctuation within ±5A. III. The above current stability is measured after the device has been in use for a period and reached thermal equilibrium. |
