Unique True Torus Core Design

CSA, and UL Approvals

Customised Designs

Very Low Flux Leakage

High Efficiency

The SRT series is our latest development in toroidal transformers. They differ in design from traditional

toroidal transformers as the advanced core construction produces characteristics similar to that of R-

cored transformers. The improved rounded section of the core leads to a substantial reduction in flux

leakage, therefore vigorously improving the units performance.
