DC Fans

DC fans are mainly utilized in environments where direct current (DC) power is available. DC fans are available in complete air flow ranges, ranging from ultra-low air flow to very high air flow. DC fans typically use armature voltage control, allowing power density to be adjusted based on the voltage, or duty cycle. Some DC fans also include intelligent electronics, including temperature, speed, and airflow control circuitry.The 9WB1412H501 is a DC fan from Yunboshi. It is designed to provide high-speed operation and stability in critical cooling or ventilation applications. It features a brushless motor for low noise and energy efficiency.The 9WB1412H501 has a wide range of applications, including thermal management, ventilation, cooling, and static pressure applications. It is typically used in HVAC and industrial applications, including air conditioners, medical equipment, electrical panels, and server and network systems.The 9WB1412H501 operates at a voltage of 12V and has a maximum air flow rating of 400CFM. It has a current rating of 1.3A and provides three operating speeds of High, Mid, and Low. It includes a DC brushless motor for low noise and high voltages for extended continuous use. It’s also designed to provide high airflow and high static pressure capabilities.The working principle of the 9WB1412H501 is based on the DC Brushless Motor (BLDC) design. BLDC motors are designed to operate without brushes, which eliminates the need to replace them because of wear or damage. The motor consists of multiple pairs of windings placed on the stator, which is located inside the fan. The windings are energized in sequence when the fan is in operation and the armature is forced to rotate due to the interaction of the electric and magnetic field. This is then magnified by the blades of the fan, thus providing the required air flow.The 9WB1412H501 also includes a speed control module, allowing users to adjust the speed and ventilation of the fan. The speed control module includes signal monitoring circuitry, a signal-processing logic block, and a speed control output stage. This setup allows the fan to automatically adjust its speed based on the load or temperature of the system, thus providing improved efficiency and reliability.The 9WB1412H501 also features an over-temperature alarm and shutdown circuit, which provides improved protection against overheating. This feature helps to protect the fan from accidental or deliberate damage. It also helps to conserve energy and reduce noise levels.Overall, the 9WB1412H501 is a versatile and reliable DC fan, designed to provide high airflow, high static pressure, low noise, and reliable operation in critical cooling or ventilation applications. It features a brushless motor, speed control circuitry, and an over-temperature alarm and shutdown circuit, making it an ideal choice for a variety of applications.
