withstand voltage of AC DC power module
Generally no. A 3 kVAC input across the input AC terminals will be applied directly to the filter, rectifier, and input-side switching/control circuitry, almost certainly causing damage.
The 3 kVAC rating is given for the insulation between input and output sides (&quot;I/P-O/P&quot;), meaning that the device is rated to not fail when 3 kVAC is applied across its input/output isolation boundary (i.e. the transformer and feedback optoisolator) while the line-neutral or line-line input voltage is within the 85-305 VAC range.
