Y23 Range Transformers

Y23 Standard Range Toroidal Transformers
AVEL's newest range the Y23 Range offers an even broader selection of ready-made toroidal power transformers, spanning 15 to 1000VA. The Range has a polyester tape finish with hardware supplied with dish mounting, nut bolt, washer and two compression pads. This style of finish has proven to be Avel's most popular method of constructing toroidal transformers for modern-day electronics. This is the most inexpensive way to meet J.I.T. schedules by purchasing "off the shelf" from the wide range of toroids that follow.

Y23 Range transformers carry a notable package of agency standards.  Our unique double-insulated primary leads eliminate an assembly step required by many safety standards.

If your requirement falls outside our Standard Range, please review our Custom Designs area, or contact us to receive a quote on a custom design.
