• Multiple outputs or isolated windings
• Shielding for EMI suppression
• Enclosures or open-frame formats
• Temperature ratings and insulation classes
• Custom leads, connectors, or terminations
• Certifications (UL, cUL, IEC, medical-grade, etc.)

We work directly with your engineering team to align specs with your exact needs.

Custom toroidal transformers are used across a wide range of industries, including:

• Medical devices and diagnostic equipment
• Data centers and telecom infrastructure
• Audio amplifiers and high-fidelity systems
• Industrial automation and control systems
• Renewable energy systems (solar, wind, battery storage)
• Oil and gas applications

Amgis serves all these industries with specialized engineering support and ISO-certified production.

Toroidal transformers offer several advantages over traditional laminated-core transformers:

• Higher efficiency: Reduced core losses and tighter magnetic coupling
• Lower audible noise: Especially important in medical and audio applications
• Compact size and weight: Ideal for space-constrained enclosures
• Minimal electromagnetic interference (EMI): Reduces risk of interference with nearby electronics
• Better thermal performance: Lower heat output for extended component life

These benefits make toroidal designs especially popular in audio, medical, industrial, and telecom systems.

A custom toroidal transformer is designed and built to meet your specific electrical, physical, and regulatory requirements. Unlike standard off-the-shelf models, these transformers are engineered with unique:

• Input and output voltages
• Power ratings and frequency (e.g., 50/60 Hz)
• Footprint dimensions
• Mounting configurations
• Thermal and environmental tolerances

Custom toroidal transformers are ideal for applications where precise performance, space efficiency, or noise reduction is critical.
