Description


new 1 PCS AVC Fan BN17569B24U DC24V 3.72A 175*69mm 4-wire centrifugal fan turbofan

The new AVC Fan BN17569B24U is a compact, efficient Turbofan fan designed for industrial applications with reliable performance.

The new 1PCS AVC Fan BN17569B24U DC24V 3.72A 175*69mm 4-wire centrifugal fan Turbofan is a compact and efficient industrial fan designed for high-performance Turbofan applications. It operates at 24V DC, providing a reliable power supply for industrial settings. The fan features a robust 4-wire construction and dimensions of 175mm x 69mm, ensuring optimal space utilization. Perfect for use in industrial equipment, this fan is built to handle demanding tasks with precision and reliability.

AVC BN17569B24U 24V DC Centrifugal Cooling Fan

The AVC (Asia Vital Components) BN17569B24U is a heavy-duty, high-performance backward-curved centrifugal fan (turbofan) designed for demanding industrial cooling applications. Measuring 175mm in diameter and 69mm in height, this fan leverages a robust 24V DC motor drawing 3.72 Amps to generate exceptional airflow and high static pressure, making it ideal for systems with high air resistance.

Equipped with a standard 4-wire interface, this fan offers advanced thermal management capabilities. It supports PWM (Pulse Width Modulation) for precise, dynamic speed control, allowing the system to scale cooling based on real-time thermal loads, thus saving energy and reducing acoustic noise. The integrated tachometer (FG) signal provides vital speed feedback to the host controller to instantly detect stalls and prevent catastrophic equipment overheating.

Industrial Applications & Thermal Advantages

Unlike standard axial fans that simply push air in a straight line, backward-curved centrifugal fans pull air in from the center and exhaust it radially at a 90-degree angle. This design creates vastly superior static pressure.

  • Telecommunication Cabinets: Pushing cold air through densely packed server racks, thick dust filters, and narrow heat exchanger fins where standard fans would stall.
  • Power Electronics: Cooling massive heatsinks on Variable Frequency Drives (VFDs), solar inverters, and battery energy storage systems (BESS).
  • High Power Draw Considerations: At 3.72 Amps (nearly 90 Watts), this fan requires a dedicated, robust 24V power supply and heavy-duty switching relays or MOSFETs if controlled directly.

Engineering Tool: Enclosure Cooling Airflow (CFM) Calculator

Determine if the cooling capacity of your fans is sufficient for your electrical cabinet. Enter the total heat dissipated by the electronics inside the enclosure and your target temperature limits to calculate the minimum required airflow in CFM and m³/h.

Wiring & Troubleshooting FAQ

1. Can I use this 4-wire fan if my power supply only has 2 wires (+ and -)?
Yes. If you only connect the 24V Positive (VCC) and Ground (GND) wires, leaving the PWM and FG wires disconnected, the fan will default to spinning continuously at 100% full speed. Ensure you properly insulate the unused PWM and FG wires to prevent short circuits.

2. The fan is running, but the motherboard reports a "Fan Stall/Failure" alarm.
This issue involves the Tachometer (FG) wire. The FG pin outputs a square wave pulse (typically 2 pulses per revolution) to indicate speed. If the fan spins but triggers an alarm, either the FG wire is severed, or the motherboard requires a "pull-up resistor" to correctly read the open-collector output of the fan's FG signal.

3. Why is the fan vibrating heavily and making a loud whining noise?
Centrifugal fans like the BN17569B24U operate at high rotational speeds. Heavy vibration is typically caused by a buildup of dust or debris unevenly coating the curved blades, ruining the delicate dynamic balance of the impeller. Clean the blades thoroughly. If the vibration persists with a metallic whining noise, the internal dual ball bearings are worn out, and the fan must be replaced immediately to prevent catastrophic failure.
