I've currently got one running at 225V in to a 5k load so ~45mA (~11W) and it's happy with that; hardly warm.

I think the info that comes with them talks about enhanced cooling being required at some point. It's a RU7088R fet doing the work.

Given that these units run at 75kHz, I suppose a "proper job" is required to enclose them such that noise is kept low?
