AC 220V to 12V/24V Power Transformer 2W EI Core 50Hz

AC 220V to 12V/24V Single-Phase Power Transformer – 2W EI Core, Full Copper Wire

This compact yet robust single-phase power transformer efficiently steps down AC 220V input to either AC 12V or 24V output, making it an ideal solution for low-voltage electronic projects, control circuits, and DIY electronics builds. Built with full copper winding wire and a fire-retardant nylon bobbin, it delivers consistent, stable power conversion in a small, durable footprint.

Why Choose This Transformer?

• Reliable Voltage Conversion: Steps AC 220V input down to AC 12V or 24V output (choose your configuration), with a 2W rated power at 50Hz frequency.
• Full Copper Wire Windings: Pure copper wire offers excellent conductivity, high-temperature resistance, and long-lasting durability compared to aluminum alternatives.
• EI Core Construction: The traditional EI laminated core design ensures low magnetic flux leakage and steady, efficient power transfer.
• Fire-Retardant Nylon Bobbin: The bobbin is made from fire-retardant nylon for added safety and structural reliability during continuous operation.
• Vacuum-Impregnated Insulation: Each transformer undergoes vacuum impregnation with insulating varnish, improving both insulation integrity and resistance to moisture and vibration.
• Simple Color-Coded Wiring: Red wire = input (220V AC); Blue wire = output (12V or 24V AC) — easy to connect with no guesswork.

Frequently Asked Questions

Q: What is the output voltage of this AC power transformer — 12V or 24V?

A: This transformer is available in two output configurations — AC 12V or AC 24V. Please select your desired output voltage option when ordering. Both versions accept AC 220V as the input voltage at 50Hz frequency.

Q: Is this transformer suitable for use with DC circuits?

A: This is an AC-to-AC step-down transformer. It outputs AC voltage (12V or 24V AC), not DC. If your application requires DC voltage, you will need to add a rectifier and filter circuit after the transformer output.

Q: What is the rated power, and will it work for my low-voltage control circuit?

A: The transformer has a rated power of 2W, making it well-suited for small, low-power control circuits, indicator lights, signal relays, and similar low-draw electronics applications that require a compact, reliable 220V step-down solution.

Q: How are the wires connected on this transformer?

A: The wiring is color-coded for ease of installation: the red wire connects to the AC 220V input, while the blue wire connects to the AC output (12V or 24V). Always ensure power is fully disconnected before making any wiring connections.
