12V 2A Switching Power Module

The 12V 2A Switching Power Module is an advanced and reliable power supply designed using switching technology to deliver electrical energy to various devices with high efficiency and minimal loss. Unlike linear power supplies, which regulate voltage by generating excessive heat, this 12V 2A Switching Power Supply uses a switching regulator that continuously alternates between fully on and fully off states. This approach reduces energy loss, extends component lifespan, and allows for a smaller, lighter design compared to linear supplies.

The 220V to 12V 2A Switching Power Supply Module operates with an AC input range of 85–264V and a frequency of 47–63Hz. It provides a 12V DC output with a maximum current of 2A, suitable for powering various electronic devices. The output voltage can be adjusted within ±10%, and the module includes advanced protection systems such as short-circuit, overload, and overvoltage protection. In the event of a fault, the protective circuit activates and restores normal operation once the issue is resolved.

The 12V 2A Power Module features a startup time of less than 2 seconds at 120V AC and less than 1 second at 230V AC. Output hold time after input loss is at least 10ms at 120V AC and 20ms at 230V AC. Dielectric strength between different sections—input to output and input to chassis—is 1500V AC for 1 minute and 500V DC for 1 minute, demonstrating high safety and build quality.

The 12V Switching Power Module is designed for a wide range of applications, including powering personal computers, mobile chargers, industrial tools, security systems, railway equipment, and various lighting systems. Its compact design and high reliability make it ideal for both industrial and home projects. Additional advantages include high efficiency, stable operation under varying environmental conditions, and the ability to work in temperatures from 10°C to 50°C with 20–90% humidity (non-condensing).

These features allow the module to perform reliably in industrial and moderately harsh environments. If you are looking for a 12V 2A Switching Power Module that is affordable, durable, and fully safe, this product is an excellent choice. Its combination of advanced technology, comprehensive protections, and versatile capabilities makes it a popular option among professionals and electronics enthusiasts alike.
