Three Phase Medical Isolation Transformer (IT Isolation Power Supply)

The Three Phase Medical Isolation Transformer (IT isolation power supply) is designed to provide clean, fully isolated power for critical medical environments where patient safety and equipment reliability are essential. By separating the input and output electrically, it effectively reduces grid interference and helps prevent fault propagation, delivering a pure and stable power supply for medical distribution systems. The solution is ideal for operating rooms, Intensive Care Units (ICU), delivery rooms and neonatal intensive care units (NICU), as well as dedicated power distribution for medical equipment. Built with high quality coils and a cold rolled silicon steel core, it offers strong magnetic permeability, lower loss, and dependable long term operation. For enhanced hospital comfort, the system supports ultra low operating noise (≤40 dB(A) within 1 meter, typical configuration), meeting quiet room requirements. The product is highly configurable: rated capacity commonly ranges from 3.15 kVA to 10 kVA (customizable), with wide input/output options from 1 V to 500 V (customizable) and 50/60 Hz frequency. Typical features include insulation resistance ≥500 MΩ, dielectric strength around 2500 VAC/min, self cooling design, and selectable protection grades (IP00 open type; IP20 available for complete systems with customizable chassis protection). It supports unattended operation and short time overload capability (e.g., 2× rated current for 1 minute, application dependent), with insulation class options such as Class F or Class H and controlled temperature rise (e.g., F ≤100K, H ≤125K). Designed for reliability, the expected service life can reach 20 years under normal operating conditions.
