Q
Why the input voltage marked on the spec. sheet is 88~264 VAC while the label on the power supply sa
A
During safety verification process, the agency will use a stricter standard -- �10%(IEC60950 uses +6%, -10%) of the input voltage

 range labeled on the power supply to conduct the test. So, operating at the wider input voltage range as specified on the spec. sh

eet should be fine. The narrower range of input voltage labeled on the power supply is to fulfill the test standard of safety regulatio

n and make sure that users insert input voltage correctly.
