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