Safety Isolating v Isolating Transformers

Les Spiteri
Anybody able to explain the difference to me as I hear both terms used?
  • I see centre-tapped maybe the difference with this being a safety isolating.

  • Whereas 0-110V is simply isolating?


And when and where would an application suit either? Normally these days all control panel transformers are 0-110Vac for control although quite often when you debug older panels you will see Centre Tapped ones?

    EN 61558-2-6  (safety isolation) double insulated and fail safe design including thermal fuse.

     EN 61558-2-4  (just isolation) lower test limits. Need not be fail to safe, any old double wound construction.

    Different symbol  there is a shield outline around the two circles.
