Medical Isolation Transformers — IT System for IEC 60364-7-710
Medical isolation transformers supply medical IT (unearthed) power systems in operating theaters and critical medical areas per IEC 60364-7-710, providing galvanic isolation so a first insulation fault does not interrupt power. Single-phase and three-phase dry-type designs with electrostatic shielding, low leakage current, and insulation monitoring compatibility for patient safety.
Key Features
- Galvanic isolation for medical IT (unearthed) systems
- Compliant with IEC 60364-7-710 medical location requirements
- Electrostatic shield between windings reduces leakage current
- Single-phase and three-phase dry-type designs
- Low inrush and low noise for clinical environments
- Compatible with insulation monitoring devices (IMD)
Applications
- Operating theaters and ICU
- Medical imaging and critical care
- Dental and veterinary treatment rooms
- Hospital laboratories
Selection Guide
Location group
Confirm Group 2 medical location per IEC 60364-7-710 for IT system requirement.
Monitoring
Pair with an insulation monitoring device (IMD) for fault indication.
Shielding
Specify electrostatic shielding for low leakage current near sensitive equipment.
- Frequently Asked Questions
Why do medical areas need an IT system?
An IT (unearthed) system with an isolation transformer means a first insulation fault does not trip the supply, so life-support equipment keeps running and the fault is only signaled by the insulation monitor — required by IEC 60364-7-710 for Group 2 medical locations.
What does the isolation transformer do?
It provides galvanic isolation between the supply and the medical circuit, limiting fault current and enabling continuous operation on a first fault.
Single-phase or three-phase?
Single-phase for smaller treatment rooms and imaging; three-phase for larger operating theater loads.
