Seems like a lot of those PDs have a high pitched whine. Maybe a bad batch of some component. I assume the original was an older off the shelf model and the replacement is fresh from the factory.

Aside from vendor performance...
One of the great differences between made in China and made in the USA electrical and electronics is that products made in the USA get tested before they are wrapped in cellophane. Even John Marles, of Megawatt who uses far east parts in his products, but circuit boards made in Texas, tests his products before shipping. So does Meanwell, from Taiwan.
I mention this, not to criticize but to try and educate. I know of no company that sells converter products that have been operationally tested before shipping. Big companies use circuit testing that probe individual switching and control circuits. Be prepared to be the "Finished Product Guinea Pig". It is the hood ornament of our times and we have to live with it. But live with it as wisely as possible.
