Product type
A toroidal transformer is a type of electrical transformer that has a doughnut-shaped core made from magnetic materials such as silicon steel or ferrite. This design allows for a more efficient magnetic field, resulting in lower losses and improved performance compared to traditional laminated transformers. Toroidal transformers are typically used in applications where space is limited and low electromagnetic interference is desired.
| Core material | Silicon steel or ferrite |
| Power ratings | From a few VA to several kVA |
| Input voltage | From 120V to 480V |
| Output voltage | Customizable, typically from 6V to 240V |
| Frequency | 50Hz to 60Hz |
| Efficiency | Typically above 90% |
When selecting a toroidal transformer, consider the required power rating and voltage levels for your application. Specify the input and output voltages, as well as the frequency of operation. It's also important to check for efficiency ratings and any specific certifications that may be necessary for your industry. Quantities can vary based on your project needs, so be clear about your requirements when requesting a quote.
