AB09005HX180B00 ADDA 5V 0.50A DC Centrifugal Blower Fan

Description

The ADDA AB09005HX180B00 is a high-performance industrial DC Centrifugal Blower with dimensions of 97 x 94 x 18 mm. Driven by a precision 4-pole Brushless DC Motor, this model is engineered as an intelligent localized cooling solution operating on a nominal 5 VDC. It delivers a powerful airflow performance driven by a rated current of 0.50 A and a power input of 2.5 W. Featuring a specialized centrifugal turbine design, it is optimized to generate high static pressure (0.58 inAq) to exhaust heat through narrow lateral paths. This specialized 4-wire version includes both a tacho signal for monitoring and a PWM input for precise variable speed control. Equipped with a premium dual-ball bearing system, the AB09005HX180B00 provides mission-critical thermal management for slim-profile industrial inverters, networking hardware, and compact automation systems.

Application
The AB09005HX180B00 is primarily utilized as a specialized inverter cooling fan for slim-profile frequency drives and compact power modules, where air must be pulled from the surface and exhausted through a side vent. Its centrifugal turbine design is essential for these applications because it can maintain a high static pressure of 0.58 inAq, forcing air through the high-impedance internal channels common in miniaturized industrial hardware. The 4-wire configuration allows the inverter’s control board to use PWM signals to dynamically adjust the fan speed based on real-time temperature, reducing energy consumption and noise during low-load periods. Beyond inverters, this 5V blower is deployed in high-density networking switches and medical diagnostic tools where the combination of compact 18mm thickness and active speed control is required for precision thermal regulation.
