AC 220V to 12V/24V Power Transformer 5W EI Core Copper Wire
AC 220V to 12V/24V Power Transformer 5W EI Core Copper Wire
AC 220V to 12V/24V Single Phase Power Transformer – 5W EI Core, Full Copper Wire
This compact and dependable single-phase power transformer is built for stable, long-lasting voltage conversion in a wide range of electrical and electronic applications. Whether you need a reliable 12V or 24V AC output from a 220V AC supply, this 5W transformer delivers consistent performance backed by quality construction materials.
Key Features
- Reliable Voltage Conversion: Converts AC 220V input to AC 12V or 24V output (select your preferred configuration), making it suitable for powering control circuits, sensors, and low-power electronic devices.
- Full Copper Wire Windings: Premium full copper wire is used throughout, offering superior conductivity, high-temperature resistance, and long operational life compared to aluminium-wound alternatives.
- Fire-Retardant Nylon Bobbin: The EI core is wound on a fire-retardant nylon bobbin, adding an important layer of safety and structural integrity to the assembly.
- Vacuum-Impregnated Insulation: Each unit undergoes vacuum impregnation with insulating varnish, enhancing moisture resistance, dielectric strength, and overall durability.
- Compact Form Factor: At just 43 × 41 × 36 mm, this transformer fits neatly into enclosures, control panels, and DIY electronic projects without taking up unnecessary space.
- Simple Wiring Identification: Red wire = input; Blue wire = output — clear colour coding for fast, error-free installation.

Frequently Asked Questions
Q: What output voltage options are available for this 5W power transformer?
A: This AC power transformer is available in two output configurations — AC 12V or AC 24V. Please select your preferred output voltage when placing your order, as this is set during manufacturing and cannot be changed after purchase.
Q: Is this transformer suitable for 50Hz and 60Hz mains supplies?
A: This transformer is rated for 50Hz operation. If your local mains supply runs at 60Hz, please verify compatibility with the application before use, as the output voltage and performance characteristics may vary slightly at different frequencies.
Q: How do I identify the input and output wires on this transformer?
A: Wiring is colour-coded for easy identification: the red wire is connected to the AC input (220V), and the blue wire is the AC output (12V or 24V). Always ensure the mains supply is disconnected before making any wiring connections.
Q: What makes this transformer safe for enclosed or panel installations?
A: The transformer uses a fire-retardant nylon bobbin and is treated with vacuum-impregnated insulating varnish, which significantly improves its insulation quality, moisture resistance, and structural durability — making it well-suited for installation inside enclosures and control panels.
