Center Tapped Step Down Transformer 220V 18V-0-18V / 9V 2A
The Center Tapped Step Down Transformer 220V 18V-0-18V / 9V 2A is a laminated EI-core power transformer designed for AC voltage conversion in audio amplifiers, analog power supplies, DIY electronics projects, rectifier circuits, and industrial control systems. The transformer converts standard 220VAC mains voltage into multiple low-voltage AC outputs suitable for dual-rail and auxiliary power applications.
Features:
- 220VAC primary input operation.
- Multi-tap center-tapped secondary winding.
- 18V-0-18VAC center-tapped output.
- Additional 9VAC intermediate taps.
- 2A maximum output current.
- Laminated EI-core transformer construction.
