Introduction
DC Fans are designed to be used in a variety of applications, from desktop and laptop computers to industrial machines and HVAC systems. The 2810KL-04W-B79-P50 is one such type of DC fan.
Application
The 2810KL-04W-B79-P50 is a four-wire DC fan, which makes it ideal for use in telecommunication and computing applications. The fan is particularly suited for those applications requiring a high airflow rate with a low noise level. It is also capable of operating at wide fluctuations in temperature without compromising its performance. The four wires from the fan enable a variety of control options, including the ability to change the fan speed based on the temperature within the system, providing a higher level of system cooling efficiency by spinning the fan faster when the temperatures start to rise.
Design
The 2810KL-04W-B79-P50 is a non-metallic, sleeve bearing type fan. It is constructed with a sturdy frame made of flame-retardant plastic, which is highly resistant to both heat and vibration. The fan has an airflow rate of 40 CFM and a static pressure rating of 0.10 in H2O, which makes it an effective cooling solution for most applications. The fan has a voltage range of 12 V to 15 V and a current rating of 0.17 A. It is rated to operate at a temperature range of -20 to 70 degrees Celsius.
Specifications
The 2810KL-04W-B79-P50 is a dual ball bearing fan, which offers a long service life of up to 50,000 hours, depending on the application and environment. The fan features an integrated 68mm x 68mm x 25mm aluminum heatsink that helps dissipate heat from the system more efficiently. It also includes a 4-pin PWM connector and a three-speed manual switch. The fan is IP68 compliant and has a noise level of 21dBA at 12V.
Working Principle
The 2810KL-04W-B79-P50 is a DC fan which is powered by a direct current (DC) power supply. The power supply supplies the fan with energy which is then converted into mechanical energy which is used to spin the blades of the fan. The fan has three speed settings that can be adjusted depending on the cooling requirements of the system. Depending on the settings, the fan can spin at speeds of 3850 RPM, 2600 RPM, or 1600 RPM. The fan can also be controlled by pulse width modulation (PWM) signals, which is an efficient way of regulating the fan’s speed and power consumption, thereby improving the system’s cooling performance.
Advantages
The 2810KL-04W-B79-P50 is an efficient and reliable fan. It is capable of running at a wide voltage range with no degradation in performance. The fan is also quiet due to its low noise level. Additionally, it is energy-saving as it has an integrated aluminum heatsink that helps dissipate heat and reduces the power consumption. The fan also features an IP68 rating, making it resistant to dust and moisture, providing a higher level of reliability in a wide range of environments.
Conclusion
The 2810KL-04W-B79-P50 is a reliable DC fan that is specifically designed for use in telecommunication and computing applications. With its wide voltage range, low noise level, PWM control, and dust and moisture resistance, it is ideal for a variety of applications where cooling is key. The fan is also energy-saving due to its integrated aluminum heatsink, which helps dissipate heat more effectively. Overall, the 2810KL-04W-B79-P50 is an ideal choice for those looking for an efficient and reliable cooling solution.
