Remote voltage sensing of minor rails makes the best regulation ever seen on a kw PSU. As well as, of course, the perfect DC output quality similar to X series.
Good luck everyone!
Well, for a double forward topography PSU, high frequency noise is common when it is trying to response to a transient load. The buzzing sounds would be louder if resonance is close to the natural frequency of electrical components in the PSU at some special loading watts. It does not...
