Hi all,
I have 2 transformer sitting around doing nothing. They are both 117v/500VA, dual secondary, same manufacturer, one is 50-0-50 and the other is 40-0-40.
Is it feasible to connect the the primary of the 40v transformer to the secondary of the 50v transformer. The objective is to get a 17dc output.
Thank you for the help.

You can get 17V RMS rectified DC but it won't be smooth.
Adding capacitor smoothing would give 24V DC (17*1.4).
For 17V DC smoothed you would want 12V from the transformer.
Or add a regulator. https://www.ebay.co.uk/itm/20361779...qZHDw1cnGZbogbclEWKa+6s4jx|tkp:Bk9SR_i21q29YQ

Very simple answer: No! No even hardly rational way to do that. Sell both and get one that does fit your need.
Such attempts would be futile: the usable output power would be ridiculous compared to the 1,000VA of the combined transformers. Think of the bulk, weight and power efficiency.
You'd be better buying a cheap, switching wall-wart from Asian origin, even if it is less durable.
You should not launch a Saturn V rocket from Florida circling the moon to drop a package in Hawaii.
Oh, they did so?
(Several times!)

So to get a 16.6666V AC RMS connection?
The practical cap-input rectifiers are "peak catchers" The peak of 16.6V RMS is 23.57V. So maybe 21V, 22V of DC. Not the 17V DC you seek.
Practicality is one thing...
Not knowing what you're doing without learning the basics of electronics is another.
Of course, wasting time on learning is all the rage these days.
Thread is now closed to further replies. Post #3 together with the advice given by others to obtain a suitable transformer for the project at hand is really the most suitable option.
