DC Fans

The 9CRA0412G402 is a type of DC fan and is widely used across numerous industries for various applications. As with any fan, the 9CRA0412G402 functions by creating air flow, which can provide cooling or ventilation solutions. This fan makes use ofPulse Width Modulation (PWM) control to achieve the desired air flow as well as its noise level.

Application Field

The 9CRA0412G402 is primarily used in several industrial and commercial settings with a need for quiet cooling solutions. This fan is often used in electronics cooling such as telecommunications, computer servers, data centers, industrial motor control systems, and military electronic systems. It is also used in medical applications, such as laboratory equipment, hospital beds, incubators, and medical instrumentation. Furthermore, the fan is also suitable for use in HVAC systems, as well as for ventilation purposes.

Working Principle

The 9CRA0412G402 works by using the spinning action of its blades to draw in and expel air in a cycle. This action is controlled by the use of PWM control input. PWM control is a method in which voltage is modulated on and off in rapid pulses of varying widths. It works by turning the voltage on or off based on a set frequency and duty cycle. This allows for the fan to be controlled precisely and be adjusted to generate the desired level of air flow.The speed of the fan is determined by the applied voltage. An increase in voltage will increase the speed and a decrease in voltage will result in a decrease in speed. The 9CRA04123G402 operates between 4.5 and 13.8 volts and has a maximum speed of 4000 RPM. The fan is rated to produce a maximum airflow of up to 58.7 CFM and a maximum static pressure of up to 2.38 mmH2O.The 9CRA0412G402 is a quiet fan with an inaudible noise rating of 20.3 dBA during its maximum RPM operation. This makes it ideal for use in quiet environments and is well-suited for cooling and ventilation purposes. The fan also includes TTL monitoring and tachometer functions and is UL, CSA, TUV, CE, and RoHS compliant.In conclusion, the 9CRA0412G402 is a versatile DC fan that is ideal for many industrial and commercial applications. It makes use of PWM control to achieve the desired air flow and noise level, and is rated for up to 4000 RPM of airflow and up to 58.7 CFM of static pressure. The fan is also quiet and compliant with numerous safety certificates.
