Help re: wiring a balanced iso transformer

[croy00]

I am using the Signal M4L series. I want to wire it for balanced power. I have an okay level of knowledge, but not enough to feel comfortable wiring this up without some more expert input. It seems like I have to use the M4L-3, and wire into the secondary, and out of the primary. But, maybe that's not necessary? Any input would be appreciated. Thanks for any advice you can provide.

Do you have a link to a data sheet?

The data sheet I found showed a dual 115V primary and a single 115V secondary.

If you wired this one backwards, you would have a balanced 230V secondary.

It may be the wrong version of the transformer. So can any of these be wired for balance power? The M4L series is on page 6 of Singal's catalog.

The M4L-1, M4L-2 & M4L-3 transformers have only a single secondary winding with no center-taps.
So no it can't be used for balanced power.

Thanks for looking. I really appreciate it.

The advantages of a balanced transformer over an isolation transformer in the real world are much smaller than advertised.
