do you need to use both seconderies on toroidal

[Gads]

help
need to purchase transformer, can i buy one rated higher and just use one
secondary output if the volt and amps of one output meets my needs?
I posted earlier but no real answer, this is basicly my main question.
thanks

Hey Gads;
Yes, only use the output you need whcih supplies the correct voltage to drive your motors. Just blank (cut and heatshrink or tape or cap) the unused secondary. Don't short them together!!!!
However, as an option, you can use both secondaries, if they are the same voltage, and up your maximum current! If you attempt this, however, make sure that the secondaries are phased appropriately. There is a thread somewhere that covers this procedure. It's pretty simple but BE CAREFUL . This stuff will turn you into a french fry in a heartbeat!

Hi

Do you want the simple answer? .
The simple answer is YES you can do that.

then you have a spare secondary to use for whatever.

Gads:

If both secondaries are of the same voltage and are wound with wire of the same size, then you can use one secondary at 1/2 the VA rating of the transformer.

Also being a toroid has nothing to do with the answer.
