Our 1-Phase to 3-Phase Step-Up Transformer is engineered to provide stable three-phase output for locations where 3-phase grid power is not available. With input options of 110V/120V/220V and output voltages of 380V/400V/440V, this transformer delivers reliable power conversion for a wide range of industrial and commercial applications.

Built with high-quality copper windings, advanced insulation systems, and strict quality-control standards, it ensures high efficiency, low noise, and long service life. This transformer is ideal for CNC machinery, industrial motors, air compressors, pumps, and equipment requiring stable 3-phase voltage.

Whether for factories, workshops, farms, or remote sites, this step-up voltage converter provides a cost-effective and safe solution to upgrade from single-phase to three-phase power.

1.The PKNY Three Phase Transformer is a versatile voltage converter designed to efficiently and reliably convert single-phase 110v, 120v, and 240v voltage inputs to three-phase 380v, 400v, and 440v voltage outputs. This makes it ideal for a wide range of applications where three-phase voltage is required, including industrial, commercial, and residential settings.

2.The transformer is equipped with an autotransformer, which means it can provide the same primary and secondary winding voltages when operated on a single-phase input. This results in improved current supply and effectiveness, as the transformer can operate independently and does not require a null winding.

3.The AHK model transformer is designed with a toroidal coil structure, which enhances power efficiency and reduces noise compared to conventional parallelogram or E-I cores. This makes the transformer quiet in operation, ensuring minimal distraction and interference in the surrounding environment.

4.The transformer is manufactured in Anhui, China, adhering to strict quality control standards and safety regulations. This ensures that customers receive a high-quality product that meets international standards and performs reliably under various conditions.

5.The PKNY brand is known for providing high-quality electrical products, and their Three Phase Transformer is no exception. The product's comprehensive attribute selection allows users to easily identify the appropriate voltage conversions based on their specific needs, ensuring a customized and efficient solution for voltage conversion requirements.
