Overview

The 1 kVA dry-type 3-phase autotransformer is designed to provide safe and efficient voltage transformation from 120V to 240V or 220V. Supporting both 50Hz and 60Hz systems, this industrial autotransformer is ideal for global applications. Constructed with H-class insulated enameled copper wire, high-permeability silicon steel sheets, and reinforced terminal connections, the unit offers excellent magnetic performance, low loss, and strong overload capacity. Other input and output voltages (120V, 190V, 230V, 240V, 400V, 415V, 480V, etc.) can be customized according to project requirements, making it a flexible solution for diverse industrial power distribution systems.

1 kVA three-phase autotransformer feature

Feature

  • H-Class Enameled Wire Coil Winding: Coils are wound with H-class insulated enameled wire, ensuring tightly arranged, skip-free turns. This construction minimizes no-load current and reduces core losses for energy-efficient operation.
  • Silicon Steel Sheet Core for Superior Magnetic Performance: The built-in silicon steel sheet core provides high magnetic permeability, low magnetic loss, and an elevated heat dissipation coefficient, contributing to long-term thermal stability and consistent transformer performance.
  • Electrophoresis-Treated Clamps with Safety-Focused Design: Clamps are processed using electrophoresis technology, resulting in burr-free edges and rounded corners that prevent mechanical damage during installation. The corrosion-resistant finish extends service life in demanding industrial environments.
  • Wide Industrial Application Compatibility: Suitable for use with CNC production equipment, SMT machines, printing machines, electrical discharge machines, laser cutting machines, plastic molding machines, medical monitoring systems, etc.

FAQ

Q1: What is the difference between a 3-phase autotransformer and an isolation transformer?

A 3-phase autotransformer uses a single continuous winding for both input and output voltage transformation, making it more compact and cost-effective. An isolation transformer has separate primary and secondary windings and provides electrical isolation. For voltage conversion applications like 380V to 220V step-down, an autotransformer is typically more economical and efficient.

Q2: Can this 1 kVA autotransformer support other voltage combinations?

Yes. Besides the standard 380V to 220V/200V, other voltages such as 120V, 230V, 240V, 400V, 415V, or 480V can be customized. Please confirm your input/output voltage and frequency requirements before ordering.

Q3: Is this dry-type autotransformer suitable for continuous industrial operation?

Yes. With H-class insulated copper windings, silicon steel core, and reinforced terminals, this 3-phase autotransformer is designed for stable long-term operation in CNC machines, automation systems, and laboratory equipment.
