DC Fans: OD4010-05LS02A Application Field and Working Principle

DC Fans find a variety of applications, from cooling computers through to moving air in hazardous or tight environments which make AC fans unsuitable. This article will explore the application field and working principle of one such DC fan, the OD4010-05LS02A.

Application Field of the OD4010-05LS02A

The OD4010-05LS02A comes with a 2.54mm x 10.16mm frame, making it suitable for use in various types of electronics. This is an important factor when considering the application field of this fan. It is suitable for use in the following areas:

• Computer cooling systems
• Networking equipment
• Office electronics
• All designs that require a high airflow/high pressure rating
• Industrial control systems and automation
• Automotive electronics

The OD4010-05LS02A boasts a powerful airflow rate of up to 52.65CFM and a static pressure of up to 2.11mmH2O. This makes it ideal for use in more demanding applications such as telecommunications systems. It also supports PWM speed control for quieter operation during idle periods.

Working Principle of the OD4010-05LS02A

The OD4010-05LS02A is a four-wire DC fan that delivers efficient cooling and reliably steady operation. This device contains a pair of magnets located in the hub of the fan, within the rotor. An electric circuit is then used to control the speed of the fan motor, which in turn moves the magnets. As the magnets rotate they generate an alternating current within the circuit, which changes as the magnets pass by the coils of the circuit. This allows the circuit to accurately measure the speed of the fan and then adjust it according to the set requirements.The OD4010-05LS02A also supports voltage control. This is achieved using a voltage detector circuit which measures the voltage supplied to the fan and adjusts the speed accordingly. This is useful for applications that require the fan to regulate itself according to temperature or system usage.

Conclusion

The OD4010-05LS02A is a reliable and versatile DC fan, suitable for a wide range of applications. Its powerful airflow rate and static pressure rating make it well-suited to more demanding environments, such as telecommunications systems. Its four-wire configuration provides efficient speed control and voltage regulation, making it an ideal choice for applications that require a fan to self-adjust according to temperature or system usage.
