Rex Power Magnetics designs and manufactures a comprehensive range of reactors and filters engineered to improve power quality, protect electrical equipment, and extend system life. Our products are built to perform reliably in demanding industrial environments where non-linear loads, switching devices, and high-frequency transients place stress on motors, drives, and transformers.
Reactors and filters play a critical role in conditioning power by reducing harmonics, mitigating voltage spikes, and limiting current surges. Each Rex unit is custom-engineered using precision-wound conductors, high-grade magnetic materials, and robust insulation systems to ensure stable performance, low losses, and long operating life.
The product family includes:
- AC Line and Load Reactors – Installed on the input or output of variable frequency drives (VFDs) and motor controllers, these reactors improve drive performance, reduce harmonic distortion, and protect sensitive equipment from voltage and current transients.
- Motor Guarding Transient Filters – Designed to protect motors and cables from steep dv/dt waveforms and reflected-wave transients produced by modern switching drives. These R-L filters suppress voltage spikes, reduce insulation stress, and enhance the reliability of VFD-fed motors.
Rex reactors and filters are available in a wide range of voltage classes, current ratings, and enclosure types, with designs tested to meet or exceed CSA, UL, and IEEE standards. Our engineering team works closely with customers to deliver optimized solutions for power conditioning and equipment protection.
Built for durability, efficiency, and precision, Rex Power Magnetics reactors and filters ensure dependable operation and improved system performance in today’s power-electronic-driven environments.
