Scavenging transformers to "bridge"

[Paulr]

Hi all,

I have an EI transformer out of an APC 600 ups that I have scavenged that gives 2 single secondaries of 14 & 26 volts when used in reverse. If I get another broken UPS of the same model off e-bay I am looking to wire them as a 26-0-26. Can anyone see any problems with this?

Also I am assuming (hoping) that both secondaries are similar VA ratings to allow them to be used in various models i.e. 14v for the smaller units & 26 for the larger units with 2 batteries in series.

The thing weighs a few kilos so should be able to source a few amps for a 35v supply for a P3a.

Any advice appreciated as all my hobbies are funded on a shoestring until their merits are proven to "THE BOSS"

Cheers
