Low Frequency Transformer EI28 Power Transformer with Casing 120V AC 60Hz 8V 200mA

1.Product Description

This EI28 low-frequency power transformer adopts the classic EI type silicon steel core structure and is equipped with a metal shielding shell, effectively suppressing electromagnetic interference and ensuring stable operation. Its primary winding supports a standard North American mains input of 120V AC 60Hz, which can safely reduce the voltage to 8V AC and provide a maximum DC output capability of 200mA. It is very suitable for use in low-power devices, circuit boards, or as a low-voltage power supply for various electronic productions, with the advantages of sturdy structure, high efficiency, and safe isolation.

1. * * Safe and reliable, isolated and protected**
Using the principle of physical electromagnetic induction for voltage conversion, achieving complete electrical isolation between the input (primary) and output (secondary) circuits. This means that the output end is not directly connected to the dangerous mains power, which can effectively prevent the risk of electric shock and provide safety protection for the backend circuits and equipment.

2. * * Metal shell, strong anti-interference ability**
Equipped with a dedicated metal casing, it not only provides sturdy mechanical protection to prevent collision damage, but more importantly, it plays a good role in electromagnetic shielding. It can effectively suppress the interference of the transformer's own magnetic field on external circuits, while also blocking the influence of external noise and improving the stability of equipment operation.

3. * * Classic EI type iron core, balancing efficiency and cost**
It is made by stacking traditional EI-28 specification silicon steel sheet iron cores. Silicon steel sheets have the characteristics of high magnetic permeability and low loss, ensuring high energy conversion efficiency at 50/60Hz power frequency. EI28 is an industry standard size that balances performance and manufacturing costs, with strong versatility and easy installation and fixation.

4. * * Clear rated power, designed specifically for low-power devices**
The output specification is 8V AC/200mA, and the calculated rated power is * * 1.6 watts (VA) * *. This design makes it highly suitable for low-power scenarios, such as powering microcontroller development boards (Arduino), small audio preamplifiers, LED strips, low-power sensors, or as an auxiliary power source for other circuits.

5. * * Plug and play, compatible with standard mains power**
The primary winding is designed to be directly connected to the standard North American and other regional power supply of * * 120V AC 60Hz * *, without the need for additional conversion or complex settings. It can be used out of the box, making it convenient and fast to obtain a safe low-voltage AC power supply, simplifying the user's development and application process.
