Find the Right Toroidal Power Transformer for Your Application

01. What Power Rating Do I Need for My Application?

Choosing the right power rating is important for reliable transformer operation. Our toroidal transformer series covers a wide range from 20W to 1500W, including 20W, 30W, 40W, 50W, 70W, 90W, 120W, 150W, 200W, 240W, 300W, 400W, 500W, 1000W, 1200W and 1500W.

If you are unsure which rating is suitable, simply provide your equipment's input voltage, output voltage, load power and application, and we can help recommend a suitable solution.

02. Can You Customize the Toroidal Transformer to My Requirements?

Yes. We provide custom toroidal transformer solutions for different equipment and electrical requirements. Input voltage, output voltage, power rating, frequency, number of outputs, mounting method, dimensions and lead wires can be customized.

You can provide a drawing, electrical specifications or application requirements, and our engineering team can help develop a suitable transformer.

03. How Do I Choose the Right Input and Output Voltage?

The correct voltage configuration depends on your equipment's power supply and load requirements. We can provide different primary and secondary voltage configurations for various applications.

When requesting a quotation, please provide your input voltage, required output voltage, power rating and frequency. Our team can then recommend the appropriate toroidal power transformer.

04. Why Choose a Toroidal Transformer Instead of a Conventional Transformer?

A toroidal transformer uses a circular core and compact winding structure, offering advantages such as compact size, efficient power transfer, low mechanical noise and a clean appearance.

This makes toroidal power transformers particularly suitable for audio equipment, electronic equipment, industrial control systems, medical equipment and space-sensitive applications.

05. What Applications Are Toroidal Transformers Suitable For?

Our toroidal power transformers are suitable for a wide range of applications, including:

• Audio & Hi-Fi Equipment
• Industrial Control Systems
• Medical & Electronic Equipment
• Lighting Equipment
• Household Appliances
• Test & Measurement Equipment
• Power Supply Systems
• Electronic Control Equipment

Different power ratings and electrical configurations can be selected according to the application.

06. Can You Provide Samples Before Bulk Production?

Yes. Samples can be provided for testing and evaluation before mass production.

This allows customers to verify the transformer’s dimensions, mounting compatibility and electrical performance before placing a larger order.

For custom projects, samples can also be produced according to the agreed specifications.

07. What Information Do You Need to Quote a Toroidal Transformer?

To provide an accurate quotation, we recommend sending:

Power Rating → Input Voltage → Output Voltage → Frequency → Number of Outputs → Dimensions → Quantity → Application

If you do not have complete specifications, don't worry. You can simply tell us what equipment the transformer will be used in and what it needs to do, and we can help determine the required specifications.
