Toroidal Transformers – Tortech’s Toroidal transformers meet modern day requirements for a smaller size, low magnetic interference field transformer. Small size and weight (approximately 50% of conventional transformers), extremely low in noise and low stray magnetic field make the toroidal transformer ideal for compact power supplies.

Due to the variety of Toroidal Transformers that we offer, the wiring colours can differ between our transformers. From this, we have detailed the circuit diagrams for our Transformers below. Please inspect the colours of the wires from your transformer and match it to the correct transformer wiring diagram. Also please note that each transformer winding has a start (S) and finish (F) as labelled in the diagrams.

  1. Danny

    Audio hobbiest here and have been buying these toroids in small quantities from tortech for many years! (20+)
    Well made and better quality then others and has warranty, which has been my biggest concern as i onsell these as a component in my equipment.

  2. Peter J (verified owner)

    No hassle purchase and prompt shipping. Extremely well made toroid and the best in Australia…. quality product.

  3. Sam

    I have ordered some designed custom toroids previously and have been happy with them.
    I could not get them wound anywhere else, so exceptionally greatful that you are actually able to make them!

  4. Jeff

    I keep the guys at Tortech busy!! Thankyou again for my custom toroids. I use these in a testing environment and i was pleased you were able to make them to my specifications in what was a short time frame. Kamal there is very helpful, thankyou mate.

  5. Stan

    Thank-you for including mounting places and bolts, these are essential !! also a handy note if you ring these guys they do volume prices which i only recently found out.

  6. Marcus Richardson (verified owner)

    Bought a small 80W toroid with two separate 25V secondaries.
    An excellent product. However it would have been good if accompanied by a description of the four colored secondary windings wires to help in connecting them either as two separate secondaries, two secondaries in parallel (twice the current), two in series (double voltage), or one combined winding with centre tap.
    It took me a fair amount of time with my multimeter measuring resistances and voltages to work this out for myself.
