DC Fans

DC Fans are a type of axial flow fans that are powered by direct current. They are used in a variety of applications, from cooling electronic components and regulating temperature in medical and industrial equipment to providing air circulation in and cooling of avionics.

1-NPL/603-1341 Application Field

1-NPL/603-1341 DC fans are designed to range in motor speed from a low of 2000 RPM to a maximum of 6000 RPM. The fan provides high static pressure along with low sound levels through its multiple speed capability. It is designed for cooling of power supplies, data processing equipment, telecommunications systems, medical equipment, industrial automation systems, automotive electronics, and avionics.

Working Principle

The 1-NPL/603-1341 DC fan has a brushless motor with permanent magnets, and the speed of the fan is adjusted by varying the voltage applied to the winding of the motor. The fan blades of the fan are made of an impact-resistant plastic material, which allows for a more efficient air flow. The fan also has a built-in electronics module to control the speed of the fan, which is adjustable through a voltage signal.The fan is designed to be powered by either an AC or DC power source. The power source used to power the fan affects the rotor speed, which in turn affects the air flow of the fan. When operating on an AC power source, the fan will achieve its best performance at lower voltage input and at higher voltage input the rotor speed will be reduced, providing lower air flow. When operating on a DC power source, the fans\' best performance is achieved with higher voltage input, and the rotor speed will decrease as the voltage input is decreased. The 1-NPL/603-1341 fan also features an active air-flow control system that prevents the fan from stalling when the air pressure increases. When the air pressure in the fan increases, the internal pressure sensor in the fan will detect this and the fan will automatically adjust its speed to maintain the appropriate air flow. This ensures that the fan does not overheat or cause air cooled components to become overheated due to inadequate air flow. In addition, the fan is designed to have minimum vibration when operating. This is achieved by its distinctive radial steel frame design and rubber dampening to reduce any noise and vibration created by the fan. The fan also features an integrated tachometer, which allows for the fan speed to be monitored and controlled for improved efficiency.

Conclusion

The 1-NPL/603-1341 DC fan is designed for a variety of applications, from cooling electronics and medical and industrial equipment to providing air circulation and cooling of avionics. Its brushless motor with permanent magnets allows for stall-free performance, while its integrated tachometer lets you monitor and adjust the fan speed for optimum efficiency. Its radial steel frame and rubber dampening design work to reduce vibration and noise, and its active air-flow control system provides the necessary air flow needed to cool components and keep them from overheating.
