Pure Copper Winding Custom Toroidal Transformer for Audio and Medical Equipment
Product Overview

This custom toroidal power transformer is engineered for equipment that demands clean, stable and quiet power. Built with a continuously wound low-loss silicon steel toroidal core and 100% pure copper windings, it delivers high efficiency, low no-load loss, extremely low stray magnetic field and near-silent operation compared with conventional EI laminated transformers.

The unit shown is configured as Input 240V AC 50Hz / Output 30.0V AC 0.2A + 30.0V AC 0.2A (dual secondary). Input voltage, output voltage, VA rating, lead length and terminal type are all fully customizable to your drawing or specification. OEM & ODM orders are welcome, with samples available before mass production.

Key Features
  • Pure copper coil, voltage fully customizable – enameled copper wire only (no CCA), giving lower resistance, cooler running temperature and longer service life. Primary and secondary voltages are wound to your requirement.
  • Stable output voltage under load, minimal voltage drop – tight coupling and optimized turns ratio keep the output steady from no-load to full-load, protecting sensitive downstream circuits.
  • Multi-colored outgoing wires – each winding uses a different lead colour so primary, secondary and multiple windings can be identified instantly, reducing wiring errors and assembly time.
  • Low noise & low EMI – the closed toroidal magnetic path suppresses mechanical hum and radiated magnetic flux, ideal for audio and precision measurement applications.
  • Compact and lightweight – toroidal construction typically saves up to 50% of the volume and weight of an equivalent EI transformer, and mounts with a single centre bolt.
  • Safety-oriented construction – flame-retardant insulation tape, layer-to-layer insulation between primary and secondary, and optional thermal fuse / thermal protector.

Frequently Asked Questions
Q1: Can you make a transformer to my own specification?

Yes. Send us your input/output voltage, current or VA rating, frequency, dimension limit and lead requirements, and our engineers will provide a design proposal and quotation.

Q2: What is the advantage of a toroidal transformer over an EI transformer?

Higher efficiency, lower no-load loss, much lower audible hum and stray magnetic field, plus smaller size and lighter weight for the same power rating.

Q3: Can the transformer be supplied with certification documents?

Please tell us your target market and applicable standard; we will confirm the available certification and test reports for your specific model.

Q4: Do you accept small trial orders?

Yes, trial quantities are accepted so you can validate performance in your own equipment first.
