Power Supply Transformers

Toroid offers a variety of standard design power supply transformers for single primary, dual primary, solid-state, multi-voltage and power supplies. With the industry’s largest selection of rectifier transformers, our customers are usually able to find a standard product to fit their needs. In the event you need different specifications, we can easily modify a standard product or give you a custom design with the same quick turnaround time.

To learn more about rectifier transformers, please visit our Technical Topics section.

Power Supply Transformers

We offer numerous Power Transformers in the toroidal design. For your convenience, we have added the expected DC output, should the transformer be rectified. The DC output is calculated with a standard full-wave bridge rectifier with a large capacitor. Any of these primaries can be easily used to configure custom secondaries at a reduced cost compared to a full custom design. This is the typical DC data when transformer supplies bridge rectifier with large filter capacities. UL/CSA Recognized.

These multi-voltage rectifier transformers are designed to work with user-provided components per schematic shown.  Note that the rated operating voltage for each component must be larger than the voltage shown in the diagram, and diodes and regulators must be rated to handle the DC current actually used. Capacitor sizes should be at least 7,000µF per ampere DC used.  Supplied with metal washer and rubber pads at no extra charge.
