What is the trouble with multi-output power supply?
Requires trial sample in a short period after the specification is fixed.
Have to pay the cost of developing power supply and its initial-cost.
Have trouble on the spending cost and the time for applying the safety standards.
Have problem of CE marking for exporting to EU.
Have to spend time more for designing one's own products or system without power supply.
The standardization of power supply.
