In Reply to: 2.5 KVA 'filter' transformer. some advice please... posted by Rtype on April 27, 2003 at 09:49:15:
So long as the transformer in your amp is rated to pull less than 2.5 KVA, you won't have any more draw on the circuit than you already do, so i would not worry about in-rush current.As a side note though, i would check into the core size of the isolation transformer being used. Some transformers have much smaller cores than others and saturation can become a problem. To avoid this, i would not pull more than 75% of the rated power from an isolation transformer with 60% - 66% offering even more headroom / less potential for hysterisis distortion to occur.
If you can find one "master" transformer that will EASILY support your whole system's power demands, that is the way to go. You can then filter again as individual components ( primarily digital ) need it. This approach minimizes "back wash" i.e. cross contamination of "digititus" flowing back into the other components that have already been filtered by the "master" transformer. Filtering of the digital gear can be done using a much smaller, less costly device that are more suitable for such small loads. Sean
