Custom T200 T235 T270 380V to 24V Toroidal Transformer for UPS and Inverters
High-performance toroidal transformer designed for 50/60Hz mains-powered equipment requiring safe, low-noise, and space-efficient step-down solutions.
Product Introduction
The Chipsen T270 is a high-power toroidal transformer built on a continuously wound grain-oriented silicon steel core. Featuring dual primary (0-115V AC) and dual secondary (0-28V AC) windings, this versatile unit can be configured for 115V or 230V mains input and can supply either a single higher-current rail or two independent isolated rails. The toroidal structure offers a lower profile, lighter weight, significantly reduced stray magnetic field, and virtually no mechanical hum compared to conventional EI laminated transformers.

Product Features
Toroidal core structure with no air gap, providing low core loss, low no-load current and high efficiency at full load
Very low audible noise - no loose laminations to vibrate, ideal for home, studio and medical environments
Low stray magnetic field, significantly below equivalent EI transformers, reducing interference with nearby circuits
Compact, low-profile shape with light net weight for easy integration into slim enclosures
Dual primary and dual secondary design covers both 115V and 230V mains with single or dual output rail configurations
Reliable isolation with separate primary and secondary layers, tested at 3000 V AC
Excellent thermal performance - round core dissipates heat evenly, maintaining temperature rise within 60 K
Full copper windings and quality silicon steel ensure long service life and stable electrical performance
Color-coded and sleeved flying leads reduce assembly time and wiring errors
100% electrical testing on every unit: turns ratio, no-load current, hi-pot and insulation resistance
