Transformer 220V 0-12V (2A)

Specifications

1. Primary Voltage:
   • The transformer’s primary winding is designed to be connected to a 220V AC power supply, which is standard in many regions globally.
2. Secondary Voltage:
   • The output from the secondary winding can vary from 0V to 12V AC. This variable output is useful in applications where different voltages within this range may be needed.
3. Current Rating:
   • With a maximum current output rating of 2A, this transformer can support devices or circuits drawing up to 2 amperes of current without risk of overheating or damage.
4. Winding Configuration:
   • The transformer consists of two windings: the primary (input) and secondary (output). The winding ratio between these two determines the voltage step-down capability.
5. Core Material:
   • Typically constructed using a laminated silicon steel core or ferrite core, which helps reduce energy losses from heat and improves efficiency.
6. Physical Design:
   • This transformer may come in various physical forms, including encapsulated models for enhanced safety or open-frame designs for easier integration into projects.
7. Safety Features:
   • The transformer provides electrical isolation between the high voltage and low voltage sides, which is essential for safety to prevent electrical shock hazards.

Applications

• Power Supply for Low-Voltage Devices: Commonly used to power various low-voltage electronic devices, such as sensors, controllers, and circuits that operate at reduced voltages.
• LED Lighting: Widely used in applications requiring illumination, particularly in LED strips or similar lighting solutions where a 12V input is needed.
• Battery Charging: Can be utilized in charging circuits for 12V or lower batteries, making it suitable for automotive or other rechargeable battery applications.
• Hobby and DIY Projects: Perfect for electronics hobbyists and makers looking to build or experiment with low-voltage circuitry, allowing for projects that require adjustable voltage inputs.
• Low-Voltage Appliances: Useful in powering small appliances that require 12V AC input, facilitating operation without the need for complex regulators or converters.

Important Considerations

• Load Management: Ensure that the total load connected to the transformer does not exceed 2A, to avoid overheating and potential failure.
• Thermal Protection: Adequate ventilation should be in place to prevent overheating during operation, especially if high loads are consistently used.
• Voltage Regulation: For applications that demand stable and precise voltage levels, additional voltage regulation devices (like voltage regulators) may be necessary, as transformers can produce slight variations in output depending on the load.
• Compliance: Always check the transformer against local safety standards to ensure safe operation, especially in commercial or widely distributed applications.

This transformer serves as a versatile component for a diverse range of applications requiring efficient and safe voltage conversion from a standard 220V AC supply down to 0-12V, particularly in low-power scenarios.
