Low Voltage Distribution Transformers

Rex Power Magnetics designs and manufactures a complete range of low-voltage distribution transformers engineered for safety, performance, and long-term reliability. Our transformers are used throughout commercial, industrial, and institutional power systems to provide efficient voltage transformation, electrical isolation, and power quality improvement.
Each unit is built with precision-wound conductors, high-grade electrical steel, and robust insulation systems to ensure low losses, excellent voltage regulation, and quiet operation. Designed and tested to meet or exceed CSA and UL standards, Rex transformers are known for their durability, flexibility, and consistent performance across a wide range of applications.
The product family includes:

• General Purpose Isolation Transformers – Provide electrical isolation and voltage transformation for safe, reliable power distribution.
• Drive Isolation Transformers – Protect variable frequency drives (VFDs) and connected equipment from transients and harmonic disturbances.
• Autotransformers – Offer compact, efficient voltage conversion where isolation is not required.
• K-Factor Rated Transformers – Handle the harmonic currents produced by non-linear loads, minimizing overheating and maintaining system efficiency.
• Harmonic Mitigating Transformers – Utilize advanced winding configurations and phase-shifting designs to cancel harmonic distortion and improve power quality.
• Encapsulated Transformers – Feature resin-encased windings for superior protection against dust, moisture, and corrosive contaminants.

Rex low-voltage distribution transformers are available in a variety of voltage combinations, kVA ratings, and enclosure types to meet diverse installation requirements. Custom-engineered designs are also available to accommodate unique electrical, environmental, or footprint specifications.

With decades of proven performance in industrial, commercial, and institutional applications, Rex Power Magnetics low-voltage distribution transformers combine superior materials, precise engineering, and exceptional reliability — delivering efficient, long-lasting solutions for modern power systems.
