Galvanic Isolation, Low Noise & Harmonic Protection

XinHuan dry-type isolation transformers provide absolute electrical separation between primary input and secondary output circuits. Designed for critical medical IT power supplies, CNC machine tool control cabinets, and sensitive industrial automation.

Galvanic Separation

Eliminates ground loops and neutral-to-ground noise voltage.

Ultra-Quiet < 35 dBA

Vacuum pressure impregnated (VPI) / toroidal low acoustic noise.

Medical IT (IEC 60364)

Leakage current <200 µA with integrated PT100 temperature sensors.

Universal Voltage Step

480V/380V/240V/220V to 220V/110V/48V/24V voltage matching.
