Product Overview
The Barrier-Type Isolation Transformer is a high-safety power solution engineered by Apex Electrics. Based on Faraday’s Law of Electromagnetic Induction, it achieves voltage transformation through the turn ratio of primary and secondary coils (Vp/Vs = Np/Ns). By incorporating high-strength insulation barriers between windings, it provides complete galvanic isolation, effectively suppressing harmonics and transient surges to protect sensitive equipment.
Key Features
✅ Superior Galvanic Isolation: Physical barriers ensure zero electrical connection between input and output, enhancing personnel and equipment safety.
✅ Low Loss & High Efficiency : Utilizing high-permeability grain-oriented silicon steel, we minimize Eddy Current Loss and Hysteresis Loss.
✅ Advanced Insulation : Class F or H insulation materials with epoxy resin casting, providing excellent moisture and flame resistance.
✅ Noise Suppression: Integrated electrostatic shielding reduces common-mode noise, ideal for data centers and medical sites.
