DC Fans: Overview

DC fans (DC stands for direct current) are a type of fan driven by electric motors that use direct current to produce rotational force. They are a reliable, energy-efficient choice for a variety of applications, and they are slightly more efficient than their AC (alternating current) counterparts. DC fans also tend to have faster start-up times, higher airflows, and higher static pressures than AC fans.

9S0912M401: Application Field and Working Principle

The 9S0912M401 DC fan from Sunon is a high-quality, reliable solution for cooling electronics and small machines. It is a small, 9 cm x 9 cm fan that can be used in a variety of applications, including cabinets, electronic enclosures, and vehicle air conditioning systems.

This fan runs on a 24VDC power supply and has a dual-ball bearing system for improved efficiency and reliability. The maximum fan speed is 11,500 RPM, with a maximum airflow of 57.3 CFM and a maximum static pressure of 3.12 mm H2O. It has a low noise level of 28 dBA at maximum speed, making it ideal for noise-sensitive applications.

The fan\'s working principle is based on a set of copper windings and two permanent magnets. When current passes through the copper windings, the resulting electromagnetic forces cause the fan to rotate. This rotation drives the blades of the fan, which move the air to create a cooling effect. The fan is also equipped with a thermostat, which can be set to regulate the speed of the fan, allowing it to be adjusted according to the ambient temperature.

Advantages of 9S0912M401

The 9S0912M401 fan offers a number of advantages over other DC fan models. It is a high-quality fan with a long lifespan, thanks to its durable construction and dual-ball bearing system. It is also energy-efficient, with a low power consumption of only 4.3W, making it ideal for energy-conscious applications. In addition, the fan is relatively quiet, with a noise level of only 28 dBA, making it suitable for noise-sensitive applications.

The fan also offers a number of features designed to make installation and maintenance easier. It is designed to be easily mounted to most surfaces, and it has a modular design that can be quickly modified to fit different application needs. The fan is also RoHS certified, meaning it is safe to use in almost any application.

Conclusion

The 9S0912M401 DC fan from Sunon is an ideal choice for cooling electronics and small machines.
