I think the lower-current ones are probably conventional supplies, but they're not linear (I don't know of any AC to DC supplies in common usage that are).

I'd look for a better-quality power supply. How much current does your module require?

The module's current rating is 500mA--I'm not sure why they sell it with a 2.2 amp supply.

Is there a company that makes high-quality/low noise 12VDC/1000mA supplies?
