Description

The 12038VA-24Q-FM is a premium-grade, original engineering DC axial cooling fan designed for high-demand thermal management in industrial inverters and automated control systems. Engineered for precise thermal regulation, this 120x120x38mm unit features advanced 4-wire PWM (Pulse Width Modulation) speed control, allowing dynamic RPM adjustment based on real-time system temperature. This ensures optimal cooling efficiency while minimizing acoustic noise and power consumption. With guaranteed technical compatibility for standard 24V DC architectures, this component offers a reliable drop-in replacement with minimal lead time for critical maintenance cycles.

Industrial Application Scenario
The 12038VA-24Q-FM is specifically engineered for variable frequency drives (VFDs), high-capacity solar inverters, and CNC machine control cabinets. In a heavy-duty industrial inverter application, the 4-wire PWM interface connects directly to the drive’s logic controller. As the insulated-gate bipolar transistors (IGBTs) generate fluctuating heat loads during motor acceleration and deceleration, the fan dynamically scales its airflow up to 5.1 m³/min. This closed-loop thermal management prevents thermal throttling, extends the lifespan of critical semiconductor components, and reduces idle power draw, ensuring continuous operation in harsh manufacturing environments.

Fans Maintenance and upkeep

1. The use environment should always be kept clean and tidy, the surface of the fan should be kept clean, there should be no sundries in the inlet and outlet air outlets, and the dust and other sundries in the fan and pipes should be cleaned regularly;

2. The fan can only operate under the condition that it is completely normal, and at the same time, it is necessary to ensure that the capacity of the power supply facilities is sufficient and the voltage is stable.

3. During the operation of the fan, if it is found that the fan has abnormal sound, the motor is seriously heated, the shell is live, the switch trips, and cannot be started, it should be stopped immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan, and a test run should be carried out for about five minutes after the overhaul to confirm that there is no abnormal phenomenon before starting the operation;

4. The fan should be stored in a dry environment to avoid moisture on the motor. When the fan is stored in the open air, there should be defensive measures. In the process of storage and handling, the fan should be prevented from bumping to avoid damage to the fan.
