Toroidal core transformers deliver high efficiency, compact size, and exceptionally low noise with minimal stray magnetic fields, thanks to their nearly ideal magnetic path. Standard designs range from fractional VA up to 30 kVA, with working voltages up to 1 kV and frequencies from 47–400 Hz (higher available by special design).
Noratel custom-designs toroidal transformers in a wide variety of forms — from flat, low-profile units to tall, cylindrical types — to suit practically any application. For specialist requirements, 3-phase toroidal transformer “banks” from 15 VA up to 90 kVA can also be supplied.
Applications
Toroidal core transformers are often chosen for high-performance, low-noise environments, including:
- Medical equipment
- Audio systems
- Precision instrumentation
- Industrial automation
- security applications
