E41X20/5W Power transformer 12v-0-12v

Dual-Output Center-Tapped Design: Features a 12V-0-12V AC step-down output (5W rated power), providing symmetric dual-rail AC power essential for driving operational amplifiers and dual-supply circuits.

Mains AC Step-Down Conversion: Efficiently steps down AC mains voltage (220V AC, 50/60Hz) to low-voltage 12V AC outputs with stable voltage regulation.

Pure Sinusoidal Output Waveform: Delivers clean, un-chopped AC power with minimal electromagnetic interference, making it ideal for sensitive analog audio preamps and signal processing boards.

Pre-Stripped Lead Wires: Flexible, color-coded primary (red) and secondary (blue) wire leads facilitate quick soldering or screw-terminal connections.

Durable EI-Core Construction: High-permeability laminated steel core wrapped with insulated copper windings ensures robust thermal performance and continuous operational duty.

Core & Construction Style: High-efficiency laminated silicon steel EI-core with copper coil windings and protective insulating tape.

Contact & Connection Style: Pre-stripped insulated wire lead connections (Red: Primary Mains AC; Blue: Secondary Center-Tapped AC 12V-0-12V).

Technical Specifications:

Model: E41X20 (5W).

Input Voltage: AC 220V (50/60Hz).

Output Voltage: AC 12V--0--12V (Center-Tapped).

Rated Power: 5W.

Mounting: Dual side flange mounting tabs with screw holes.

Color: Silver metallic core with yellow coil wrap and red/blue leads.

Usage Advice: Keep total continuous circuit power draw within 5W. Ensure the primary high-voltage AC leads are properly insulated inside project enclosures.

Maintenance: Mount securely using side flanges to prevent mechanical vibration noise. Keep free of dust accumulation and moisture.

Essential Component for Dual-Rail Audio Circuits: Position as the primary step-down power transformer for DIY audio preamplifiers, operational amplifier power supplies (+15V / -15V or +12V / -12V rectified DC), active tone controls, and measurement instruments.

Highlight Center-Tapped Flexibility: Emphasize its 12V-0-12V center-tapped secondary winding that easily creates symmetrical dual positive/negative power rails with a bridge rectifier setup.

Recommended Cross-Sell Add-ons: Pair with AC220-9V Transformer For NY-D01 100A/40A Spot Welding Controller Board, AC to DC 1N4007 full bridge rectifier module, TDGC Meter Display Variac 0-250V Single Phase 2KVA AC Regulator, and ESD antistatic mat 50x40CM PCB Welding Mat.
