12-0-12 12V 0.5A Center Tapped Step Down Transformer

Description

A 12-0-12 12V 0.5A center-tapped step-down transformer is an electrical component designed to reduce AC voltage levels. It has a primary winding and two secondary windings, each providing 12V AC output. The key feature is the "center tap" on the secondary winding, creating a 0V reference point. This allows for both positive and negative 12V outputs, making it useful for various electronic circuits.   

Key Features

• Center-Tapped: Provides both positive and negative 12V outputs.
• Step-Down: Reduces input voltage to 12V AC.   
• Voltage/Current Rating: 12V 0.5A indicates the output voltage (12V) and maximum current (0.5A) per secondary winding.   
• Electrical Isolation: Provides isolation between the primary and secondary windings, enhancing safety.   
• Compact Size: Typically small and lightweight, suitable for various applications.

Specifications (Typical Values)

• Primary Voltage: 240V AC (may vary depending on region)
• Secondary Voltage: 12V AC (each winding)
• Secondary Current: 0.5A (each winding)   
• Frequency: 50/60Hz   
• Isolation Voltage: 1500V or higher
• Efficiency: Typically around 80-90%

Applications

• Audio Amplifiers: Providing dual-polarity power supplies.
• Power Supplies: Used in various electronic devices requiring ±12V DC power.
• Laboratory Equipment: For various electronic testing and experimentation.
• Hobby Electronics: In DIY projects and electronic circuits.
