DC Fans

DC fans offer a broad range of applications from industrial to medical to commercial use. They are designed to provide a range of airflow characteristics such as cooling and protection from environmental contaminants. DC fans operate by creating airflow using electric current driven by a motor. The 9G1212H402 model DC fan is a miniature, dual-bearing fan designed with a robust die-cast aluminum housing and a low profile profile. It features a high speed and low noise operation. It is suitable for use in a wide variety of equipment, including electronic cabinets, IT and communication equipment, medical equipment and telecommunications equipment.

Operation and Control

DC fans are driven by electric current in order to operate. The motor of a DC fan uses electric current converted from direct current (DC) power supply. The speed of the fan can be adjusted by varying the voltage that is fed to the motor. This provides control and flexibility to the user.

Working Principle

The working principle of a DC fan involves the motor being powered by an electric current. The current creates an electromagnetic field around the motor which interacts with the fan blades, creating movement in them. This action creates a low pressure area at the leading edge of the fan despite the relatively high pressure behind them. This low pressure then draws air or other fluids through the fan as the blades move.

Design Features

The design of a DC fan features multiple design elements that help it achieve the desired outcome. These can include the number of blades, the shape and size of the blade, the design of the motor, the fan power and speed, the blade type and size and the safety features. The 9G1212H402 DC fan is designed with a motor of 12VDC and a rated speed of 13500 rpm. It features a 4-wire PAB type connection, a die-cast aluminum housing, and a low profile profile. The fan has seven blades and is designed to operate on a temperature range of 0°C to +70°C. It has a rated power of 5.8W and an airflow of 15.65CFM along with an acoustic noise level of 44dB. The fan has protective features such as a rotor lock system and a reverse polarity protection. The rotor lock system provides protection to the motor against unexpected motor stall or fan Jam conditions. The reverse polarity protection helps to protect the fan from power supply malfunctions.

Applications

The 9G1212H402 DC fan is designed for cooling and protection from environmental contaminants. It is suitable for use in a wide variety of equipment, including electronic cabinets, IT and communication equipment, medical equipment and telecommunications equipment. The fan is small and lightweight, making it suitable for applications where space is at a premium. The fan’s low noise operation makes it particularly suitable for use in noise-sensitive applications. In conclusion, the 9G1212H402 DC fan is a miniature, dual-bearing fan designed with a robust die-cast aluminum housing and a low profile profile. It is suitable for use in a wide range of equipment, including electronic cabinets, IT and communication equipment, medical equipment and telecommunications equipment. The fan is driven by an electric current and operated by the speed varying voltage that is fed to the motor. The design features of the fan include a motor of 12VDC, a rated speed of 13500 rpm, a 4-wire PAB type connection, a die-cast aluminum housing, and a low profile profile. It is designed to operate on a temperature range of 0°C to +70°C with a rated power of 5.8W and an airflow of 15.65CFM and an acoustic noise level of 44dB. The fan also has safety features such as a rotor lock system and a reverse polarity protection.
