DC Fans are a kind of motor-driven fan, which is widely used in industry. It has the characteristics of simple structure, low power consumption, reliable operation, low operating noise, no spark, no heat effect, light weight, long service life and easy installation and maintenance. The 9CRA0412G502 is a kind of typical DC Fan.

The 9CRA0412G502 is mainly used in the industrial automatic control area. It has the characteristics of low noise, strong airflow, small volume and high air volume. It is designed for storage cabinets, outdoor heat exchangers, industrial enclosures, temperature control cabinets and other equipment driving, and it can also be used for outdoor installation to protect equipment from dust and moisture. Its maximum air flow is nearly 18 CFM, and it can achieve a maximum pressure up to 12.45-inch H 2 O.

Adopting brushless motor technology, which can reduce noise and temperature, and increase the service life of the fan. The motor consists of a set of electromagnetic coils, a permanent magnet mount and a PCB (printed circuit board). The rotor consists of a permanent magnet monolith mounted in the center of the rotor. Through winding current control, the stator creates an electromagnetic force that acts between the rotor and the stator, pushing the fan blades to produce rotation.

Generally, this kind of DC fan has two working modes which are DC voltage and PWM speed control. When used in DC voltage mode, the fan will constantly supply DC power, and it will not be affected by changes in the surrounding environment. However, when it is used in PWM speed control mode, the fan will read the signal of the PWM, and change its speed and power according to the signal, which can adjust its spinning speed accurately and reduce the power consumption.

In addition, the 9CRA0412G502 DC Fan has the features of reverse connection protection, over current protection, high temperature protection and waterproof protection, which can ensure the safe operation of the fan. It has a wide operating voltage range, and can work at a voltage of 8-13.2V; the standard terminal type is 0.187 inch (4.8mm), and the current, speed, and voltage can be customized.

The 9CRA0412G502 is a kind of DC fan widely used in the industry, with the features of low noise, strong airflow, and protection functions. It can be used to protect equipment from dust and moisture, and also can be used as a drive for industrial automatic control.
