Descriptions
A "Ball bearing 48V 4 lead wires DC axial flow fan" is a type of cooling fan designed to operate with a 48-volt direct current (DC) power source.
Here's a breakdown of the description:
Ball Bearing: This fan uses ball bearings in its motor, which reduces friction, increases durability, and extends the operational lifespan of the fan. Ball bearing fans are known to be more reliable than sleeve bearing fans, especially in high-temperature environments.
48V DC: The fan operates on 48 volts of DC power, making it suitable for applications that use this voltage, such as industrial equipment, telecom devices, or other specialized electronics.
4 Lead Wires: It has four wires, which typically indicate a fan with advanced control or feedback mechanisms. The wires usually include power, ground, and control signals (like speed control via Pulse Width Modulation or tachometer feedback to monitor fan speed).
Axial Flow Fan: This type of fan moves air along the axis of the fan, meaning the airflow direction is parallel to the fan shaft. Axial flow fans are commonly used for ventilation, cooling, and air circulation in various electronic or mechanical systems.
Main Features
Ball Bearing System: The ball bearings allow for smooth operation and greater longevity, especially when the fan is used in environments with high heat or demanding conditions.
- 48V DC Power: The fan is compatible with 48V DC power systems, commonly found in industrial settings, telecom applications, and high-power electronics.
- 4 Lead Wires:
- Power and Ground: Two wires provide power and ground connections.
- Control (PWM): A wire for pulse-width modulation (PWM) allows you to adjust the fan speed for efficient cooling based on system requirements.
- Tachometer/Feedback: The fourth wire typically provides RPM feedback, letting the system monitor the fan’s performance in real-time.
- Axial Flow Design: The axial design provides high airflow with relatively low pressure, making it ideal for general cooling applications, such as in computers, server racks, industrial machinery, and telecom equipment.
- Efficient Cooling: Axial fans are designed to move air efficiently through electronics, helping to maintain temperature levels and prevent overheating.
- Durability: The combination of ball bearings and robust design ensures that the fan will have a long operating life, even under continuous or heavy use.
