AC 220V to 12V/24V Power Transformer 10W 50Hz EI Core Single Phase
AC 220V Single Phase Power Transformer – 10W, 50Hz, 12V/24V Output
This compact and reliable single-phase power transformer steps down AC 220V input to a selectable AC 12V or 24V output, making it an essential component for low-voltage electronics, lighting circuits, control systems, and DIY electrical projects. Built with full copper winding and a fire-retardant nylon bobbin, it delivers stable, long-lasting performance in a small footprint.
Made in Mainland China.
Key Features
- Stable Voltage Conversion: Converts AC 220V input to AC 12V or 24V output (model/configuration dependent) with rated 10W power at 50Hz.
- EI Core Construction: High-quality EI laminated core ensures efficient magnetic flux and minimal energy loss during operation.
- Fire-Retardant Nylon Bobbin: The transformer bobbin is manufactured from fire-retardant nylon material, contributing to a safer and more reliable build.
- Full Copper Winding: Pure copper wire provides excellent electrical conductivity, high-temperature resistance, and long-term durability.
- Vacuum-Impregnated Insulation: Each unit undergoes vacuum insulating varnish treatment, enhancing both insulation performance and structural integrity.
