TFA0412DN-AC3E Delta 12VDC 1.05A 40x40x28mm Axial Fan

Description

Delta TFA0412DN-AC3E is a high-performance axial cooling fan measuring 40 x 40 x 28 mm, operating at a nominal 12 VDC with a rated current of 1.05 A. The unit features a robust dual ball bearing system and a 4-wire interface supporting PWM speed control and tachometer output. Constructed with a UL 94V-0 rated plastic frame and impeller, the fan utilizes a brushless DC motor to deliver high static pressure and concentrated airflow. The internal mechanism is designed for continuous operation in high-impedance environments, incorporating locked rotor protection and polarity protection to ensure hardware integrity.
