Comprehensive Product Overview

Deep dive into the engineering, applications, and specifications of our Hot Selling Wide Use 200 Kva 300kva 500kva 50hz Three Phase to Single Phase Isolation Transformer.

Versatile Power Phase Conversion

Experience reliable power conversion with our high-capacity Three Phase to Single Phase Isolation Transformers. Available in 200kVA, 300kVA, and 500kVA models, these units efficiently convert 3-phase power to single-phase while providing robust electrical isolation. Perfect for diverse industrial applications requiring clean, stable 50Hz power.

By utilizing an optimized, low-loss magnetic core and high-grade copper or aluminum windings, it guarantees reliable, continuous operation with minimal energy waste, even in the most demanding environments. This transformer is ideal for balancing loads when single-phase equipment must be powered from a three-phase supply.

  • True galvanic isolation protects sensitive electronics from common-mode noise and transients.
  • Available in high capacities (200kVA to 500kVA) to match heavy industrial load requirements.
  • Dry-type design requires minimal maintenance and poses no risk of fluid leakage.
3 Phase to 1 Phase Isolation Transformer Overview

Engineering Excellence at Every Level

Our isolation transformers are built utilizing state-of-the-art manufacturing processes to ensure maximum efficiency, durability, and operator safety.

Galvanic Isolation

True Galvanic Isolation

Electrically separates the primary and secondary windings, effectively blocking DC signals, high-frequency noise, and protecting equipment from ground faults.

High Efficiency Core

High-Efficiency Core

Constructed with premium cold-rolled grain-oriented silicon steel sheets, stacked with precision to minimize core losses and operational noise.

VPI Windings

Precision VPI Windings

Vacuum Pressure Impregnated (VPI) windings provide superior dielectric strength, excellent heat dissipation, and high resistance to environmental moisture and dust.

Versatile Industrial Integration

The 3-phase to 1-phase isolation transformer is essential for providing clean, stable, and safe power to localized systems. It is particularly useful when you need to power large single-phase loads from a three-phase supply while minimizing phase unbalance.

Industrial Heating & Welding: Powering large single-phase induction heaters or welding equipment from a standard factory 3-phase grid.
Medical & Laboratory Facilities: Ensuring isolated, highly stable voltage to safeguard sensitive diagnostic instruments and analytical equipment.
Data Centers & IT Infrastructure: Preventing ground loops and electrical interference in critical server and communication networks.
