AD5024UB-D7F ADDA 24V 0.12A 50mm DC Axial Fan

Description

The ADDA AD5024UB-D7F is a high-performance compact DC Axial Fan with dimensions of 50 x 50 x 15 mm. Driven by a precision Brushless DC Motor, this 5015 series model is engineered as an intelligent localized cooling solution operating on a nominal 24 VDC. It delivers a reliable maximum airflow of 14 CFM (23.8 m³/h) at a rated speed of 5500 RPM. With a rated current of 0.12 A and a power input of 2.88 W, it is specifically designed to provide steady thermal regulation for power electronics in space-constrained industrial environments. This specialized 4-wire version includes both a tacho signal for monitoring and a PWM input for precise variable speed control. Featuring a premium dual-ball bearing system and a 7-blade aerodynamic impeller, the AD5024UB-D7F provides mission-critical durability (70,000 h @ 40 °C) for industrial inverters, localized hot-spot cooling on driver boards, and compact power modules.

Application
The AD5024UB-D7F is primarily utilized as a specialized inverter cooling fan for localized heat dissipation in frequency drives and high-density power modules. Its 15 mm slim profile is a critical design choice for mounting within the restricted internal cavities of inverter cabinets, where it is often used to cool IGBT gate drivers or internal control power supplies. The 4-wire configuration allows the inverter’s control logic to use PWM signals to dynamically adjust the fan speed based on real-time temperature, reducing energy consumption and noise during low-load periods. The 5500 RPM operation generates 0.17 inAq of static pressure, sufficient for forcing air through secondary heat sinks, while the dual-ball bearing system ensures a service life of 70,000 hours, ensuring the operational stability of mission-critical 24V industrial automation and power systems.
