PFE0381BX-Q04C-S99 SUNON 12VDC 51.6W 140x38mm Axial Fan

Description

The SUNON PFE0381BX-Q04C-S99 is a high-performance axial cooling fan measuring 140 x 140 x 38 mm, engineered with a nominal voltage of 12 VDC and a high power consumption of 51.6 W. This unit features a robust dual ball bearing system and a 4-wire interface supporting Pulse Width Modulation (PWM) for precise speed control and an Auto Restart function for operational safety. Constructed with a thermoplastic PBT frame and impeller, the fan delivers a maximum airflow of 297.9 CFM and a static pressure of 1.18 inch-H2O at a peak rotational speed of 6800 RPM. The internal motor architecture utilizes SUNON’s brushless DC technology, drawing a rated current of 4.3 A to maintain high-velocity thermal displacement in high-impedance environments.
