Why do we custom isolation transformers? Flexibility is the key advantage, among the others. Here we list a few options and actually there are more than meet the eye.
Other than input voltage adaptation, and output voltage tuning, custom isolation transformers can have multiple inter-isolated outputs by having separate secondaries with different (or the same) VA to cater for different gears that have different power consumption, and input voltage requirements. Inter-isolated means the secondaries are shielded from interfering from each other rather than affecting each other for quieter operations, on top of being shielded from the primary / incoming mains.
Above is a super flexible isolation transformer where user can fine tune to 16 combination of voltages, step-up, down, or equal. The step can be 10V-step as what's shown above, or 5V-step, or 20V-step, up to user's requirement.
Other than the above, another example would be to have multiple secondaries with multiple VAs and voltage requirements, connected to several output sockets so that user can connect to source, pre-amplifier, power amplifier, DAC, AV equipment, and etc. Outputs can be balanced or unbalanced, or both.
Another even more extreme case is, in a single chassis fully built isolation transformer system, internally it can have multiple physically separated isolation transformers, each supplying to a single socket to the external world. This would save space by taking up only 1 rack space than multiple, and yet have the beauty of each equipment connecting to a separate isolation transformer.The possibilities are limitless.
