Toroidal Products for Medical Equipment and Applications

Select a Toroid Medical Grade Isolation Transformer for Proven Reliability and Power

Our Experience

Medical equipment requires transformers to meet strict reliability and safety standards. We specialize in toroid medical grade isolation transformer models that will last the life of your equipment, continually providing proven protection and power.

Our Solutions

Our standard toroid medical grade transformer series is designed for a 120/240 V, 50/60 Hz input, and they’re equipped with dual 120 V outputs. We offer various VA power ratings ranging from 100 to 5000 VA. This line carries UL/c-UL recognition to applicable standards. Furthermore, Amgis has obtained a CB Test Certificate to IEC 60601-1 3rd edition for this line, which allows our products to be incorporated in medical products intended for use in Europe.

We have also developed a line of enclosed toroid medical grade isolation transformer for North American applications. Our MEDBOX medical isolation transformer product line has obtained a UL listing, a testament to the dependability of our transformers. The MedBox products are designed for a 120 V, 60 Hz input and are equipped with various 120 V outputs, depending on product power rating. We have five VA power ratings readily available: 300 VA, 600 VA, 900 VA, 1200 VA and 1800 VA.

In addition to our standard line of medical grade products, we can also design a custom medical grade toroidal transformer to meet your specific input and output requirements.

A medical-grade toroidal transformer is an electrical isolation device specifically designed for use in patient-connected medical equipment. These transformers are built to meet strict safety and regulatory standards, such as UL 60601-1 and IEC 60601-1, which govern leakage current, insulation, and reliability. Their toroidal (doughnut-shaped) core minimizes electromagnetic interference (EMI) and audible noise, key considerations in hospital and clinical environments.

Category: Medical

UL 60601-1 is a safety standard that outlines the requirements for electrical medical equipment used in patient care. It governs aspects such as insulation, leakage current, mechanical strength, and flammability. Compliance with UL 60601-1 is essential for manufacturers who want to sell their medical devices in the U.S. and many global markets.

Toroidal transformers are used in a wide range of diagnostic, monitoring, and therapeutic equipment, including:

  • MRI and CT scanners
  • X-ray and ultrasound systems
  • Patient monitors
  • Infusion pumps and dialysis machines
  • Surgical tools and imaging consoles

These transformers support stable, clean power delivery and protect patients and equipment from electrical faults.

Category: Medical

Toroidal transformers offer several technical and functional advantages that make them ideal for medical applications, including:

  • Low electromagnetic interference (EMI): The closed-loop core design minimizes radiated noise that can disrupt sensitive medical electronics.
  • Compact size: Their efficient core geometry allows for smaller footprints, ideal for portable or space-constrained medical devices.
  • Superior efficiency: Lower core losses translate into less heat generation, helping maintain equipment longevity and performance.
  • Quiet operation: With reduced mechanical hum, toroidal transformers are ideal for environments requiring minimal audible noise, such as operating rooms and intensive care units.
  • Enhanced safety: Their design supports lower leakage currents, essential for patient-connected devices.
Category: Medical

Electrical isolation is critical in medical environments to protect patients and caregivers from dangerous leakage currents or equipment malfunctions. This is especially important in:

  • Patient-connected devices, where even low-level current can pose serious risks.
  • Diagnostic and imaging equipment, which requires precise, interference-free power.
  • Emergency and critical care settings, where equipment failure can be life-threatening.

Isolated transformers, such as those from Amgis, help ensure compliance with UL 60601-1 standards and promote safer, more reliable operation.
