The 20V 6.5A 130W switching power supply is a mid - range power - delivery device that strikes a balance between power output and energy efficiency. With a rated output voltage of 20 volts and a maximum current capacity of 6.5 amperes, resulting in a total power output of 130 watts, it is tailored to meet the power needs of a diverse range of applications.

In the realm of multimedia projectors, the 20V 6.5A 130W switching power supply plays a critical role. Projectors require a stable power source to drive their high - intensity lamps, cooling fans, and digital processing units. The 20 - volt output provides the necessary voltage for these components, while the 6.5 - ampere current capacity ensures that they receive sufficient power to operate without interruption. In the field of 3D printing, this power supply can power the extruder motors and heated beds of small - to - medium - sized 3D printers. The extruder motor needs a consistent electrical supply to precisely melt and extrude the printing material, and the heated bed relies on the power supply to maintain the appropriate temperature for optimal printing results.

Technologically, the 20V 6.5A 130W switching power supply utilizes advanced pulse - width modulation (PWM) technology. By adjusting the duty cycle of the switching signal, it can accurately regulate the output voltage and current, ensuring stable power delivery even under varying load conditions. The power supply also features a high - frequency switching design, which allows it to achieve an efficiency rate of up to 85 - 90%. This high efficiency not only reduces energy consumption but also minimizes heat generation, enabling the power supply to operate continuously without the risk of overheating. Additionally, it is equipped with multiple protection features, including over - voltage protection, over - current protection, and short - circuit protection, which safeguard both the power supply and the connected devices from potential damage.
