DC Fans

DC fans, or direct current fans, are fans that operate by leveraging direct current power from a variety of sources, including from battery power in automobile applications, from solar power sources, and even from recessed light fixtures. They are used in a variety of applications, ranging from cooling components, to providing air circulation in enclosed spaces, to providing electrical current to power small motors. DC fans come in a range of sizes and shapes, and vary by fan speed, airflow, noise level, and power consumption.

4715KL-04W-B20-E00 application field and working principle

The 4715KL-04W-B20-E00 is a DC fan specifically designed for keeping electronic components cool. It features a sleeve bearing motor that is quiet and reliable and low power consumption with a low noise level. The fan has a 4-wire structure, with each wire controlling different features of the fan: PWM, Powering On/Off, Tachometer, and Ground. The fan can be adjusted to three fan speeds depending on the application, using Pulse-Width Modulation (PWM). The fan is also rated UL, CE, and TUV, providing additional safety and peace of mind.

In terms of working principle, the basic steps include the following: 1) electricity is input into the motor from a power source, which produces a magnetic field; 2) the magnetic field engages with the fan blades, causing the fan to rotate; and, 3) air is drawn into the fan and expelled in the direction of the arrow on the fan housing.

Conclusion

The 4715KL-04W-B20-E00 DC fan is a reliable and safe choice for keeping electronic components cool. It features a quiet and reliable motor, low power consumption, and low noise level. The fan\'s four-wire structure offers users flexibility in controlling fan speeds and powering on and off. It is also UL, CE, and TUV certified, providing additional safety and peace of mind.
