Product Description
The three-phase isolation transformer is a critical component for various power supplies and electrical equipment. It is manufactured using high-quality materials and advanced technology to ensure complete electrical insulation between the primary and secondary sides. This design ensures that a short circuit on the primary side does not affect the secondary side, protecting sensitive downstream equipment.
Beyond voltage transformation, these transformers isolate the third harmonic of the power grid. With primary and secondary copper foil shielding, they effectively prevent grid harmonics from interfering with the equipment. It is particularly suitable for import and export equipment ranging from 0.1KVA to 1600KVA, operating under AC 50/60Hz with input/output voltages up to 1600V.
