Hi all,

I’m working on a project and was just curious because I can’t find a definitive answer on connecting the earth with the transformer. At the moment we have the 2 x 25v secondary’s in series to give 1 x 50v and was wondering if the series join should be connected to the chassis ground?

I can provide a diagram of how the transformer is connected if it will allow you to understand what I mean.

Kind regards,
Oliver

The secondary GND reference for that supply is purely optional and as already mentioned, depends whether the subsequent circuitry will require or need it.
At that voltage, the need for Gnd ref would be for other than safety, noise - shielding etc.
Max.
