Product Description

The R-Type transformer features a continuously wound, non-cut core made from grain-oriented silicon steel, resulting in a circular cross-section that delivers exceptional electromagnetic performance. Specifically engineered for medical equipment, this transformer operates with near-zero noise and ultra-low leakage flux—critical for sensitive diagnostic and life-support devices.

Its cylindrical coil design minimizes copper losses, reduces temperature rise, and achieves efficiency exceeding 97%. The primary and secondary windings are wound on separate flame-retardant PBT bobbins, ensuring high dielectric strength and complete electrical isolation, meeting stringent medical safety standards. Compact, lightweight (30% smaller than EI types), and quiet, it is the preferred power solution for patient monitoring systems, infusion pumps, and imaging equipment.

✔ Magnetic Circuit Performance: Seamless R-shaped silicon steel core structure effectively reduces iron loss, making the product more energy-saving.

✔ Near-Silent Operation: The gapless wound core effectively absorbs magnetostrictive stress, ensuring a quiet environment for operating rooms.

✔ High Efficiency: Achieving over 97% efficiency, reducing thermal stress on adjacent components in compact enclosures.

✔ Safety Standards: High-standard insulation processes ensure high dielectric strength, meeting strict medical safety requirements.
