The characteristics and applications of American standard linear power supplies

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.28
In electronic devices and systems, the power supply is a very important component, responsible for providing the electrical energy required for the normal operation of the equipment. There may be differences in power specifications and standards among different regions and countries, among which American linear power supply is a common power specification widely used in regions such as the United States and Canada. This article will introduce the characteristics, applications, and differences between American standard linear power supplies and other power supply specifications.

The characteristics of American standard linear power supply

American standard linear power supply is a power supply that converts alternating current into direct current, and its characteristics mainly include the following aspects:

1. High safety: The American standard linear power supply adopts linear regulator technology, which has lower output ripple and noise, and also has good overload protection function, making it safer and more reliable to use.

2. High efficiency: The conversion efficiency of American standard linear power supplies is generally above 80%, and their operating temperature is low, which is conducive to extending the service life of the power supply.

3. Small size and light weight: The size and weight of American standard linear power supplies are relatively small, making them easy to carry and use.

4. Moderate price: Compared to other types of power supplies, American linear power supplies are more affordable and suitable for use in general consumer electronics products.

The application of American standard linear power supply

American standard linear power supplies are widely used in various electronic devices and systems that require direct current, such as communication equipment, computers, medical devices, industrial control equipment, etc. Due to its safety, reliability, high efficiency, small size, and light weight, American linear power supplies are particularly favored in portable and mobile devices.

Differences from other power supply specifications

1. Difference from switch mode power supply: Switch mode power supply is an efficient power conversion scheme, but its working principle is different from American standard linear power supply. The switching power supply adjusts the output voltage through a high-speed switching circuit, so its volume is small, but the ripple and noise are relatively large. The American standard linear power supply adopts linear regulator technology, which has lower ripple and noise, but larger volume.

2. Differences from European standard power supplies: European standard power supplies (such as CEE7/13) differ from American standard linear power supplies in terms of voltage and frequency. Therefore, it is necessary to pay attention to the power specifications and standards in different regions when using to avoid compatibility issues.

In short, American standard linear power supply is a safe, reliable, efficient, small in size, and lightweight power supply, widely used in various electronic devices and systems. Compared with other types of power supplies, American standard linear power supplies have lower ripple and noise, and are moderately priced, making them easy to meet the needs of general consumer electronics products. When using, it is necessary to pay attention to the power specifications and standards in different regions to ensure the compatibility and normal operation of the equipment.
