Key Specifications:

✔ Input Voltage: 220V AC (50/60Hz) ✔ Output Voltage: 12V-0-12V AC (center-tapped, 24V total) ✔ Current Rating: 1A (per 12V winding, 0.5A if using full 24V) ✔ Power Capacity: 12VA (12V × 1A) ✔ Winding Material: Copper (low-loss, high-efficiency) ✔ Core Type: Laminated Iron Core (reduces hum/noise) ✔ Insulation Class: Class B (130°C) – Heat-resistant enamel coating ✔ Mounting: Vertical or horizontal chassis mount (with fixing brackets)

Features & Benefits:

• Center-Tapped Design – Enables full-wave rectification (requires 2 diodes instead of 4).

• Dual Voltage Output – Use 12V AC (half winding) or 24V AC (full winding).

• Low Noise & Vibration – Robust core minimizes buzzing.

• Overload Protection – Safely handles brief current surges.

Typical Applications:

• Power Supplies – For ±12V DC circuits (after rectification/filtering).

• Audio Amplifiers – Dual-rail voltage for op-amps, preamps.

• Battery Chargers – Low-current charging circuits.

• DIY Electronics – Bench power supplies, Arduino/Raspberry Pi projects.

Wiring Guide:

• Primary (Input): Connect 220V AC to the two input wires.

• Secondary (Output):

  • 12V AC: Use 0V (center tap) + 12V (for half voltage).

  • 24V AC: Use both 12V ends (ignore center tap).

• Rectification: For DC output, add a bridge rectifier (or two diodes for CT full-wave).

Safety Notes:

⚠ High Voltage Risk – Ensure proper insulation and grounding. ⚠ Do Not Overload – Exceeding 1A may cause overheating. ⚠ Use a Fuse – Recommended on the primary side (e.g., 250mA slow-blow).
