5V 5A Switching Power Supply (25W)

A 5V 5A switching power supply is designed to convert 110V or 220V AC into a stable 5 volts DC with a current capacity of 5 amps, providing up to 25 watts of power. This type of power supply is typically used for low-voltage, high-current applications, such as:

• Raspberry Pi clusters or SBCs

• LED strip lighting

• USB hubs or charging stations

• Small DC-powered gadgets and circuits

• Microcontroller-based projects (Arduino, ESP32, etc.)

Thanks to its switching technology, it operates with high efficiency, typically above 85%, and remains cool and compact even during continuous use. Unlike bulky linear power supplies, a 5V 5A SMPS uses high-frequency switching transistors and filtering components to deliver clean, regulated power while minimizing size, weight, and heat.

It usually includes protection features like over-voltage, over-current, short-circuit, and over-temperature protection, making it ideal for both hobby electronics and embedded systems.
