Description
Delta EFC1748DG is a 48VDC 172x172x51mm Axial Fan optimized for high-density thermal management in industrial environments with extreme system impedance. This heavy-duty cooling solution features a sophisticated dual ball bearing architecture and a high-torque DC motor designed for continuous operation at 1.84A. The aerodynamic impeller is engineered for maximum structural rigidity to maintain stability at high RPMs, effectively reducing thermal impedance in restricted airflow paths. Delivering 110.4W of cooling power, this unit integrates 4-wire PWM speed control for precise thermal regulation, ensuring optimal efficiency in variable frequency drive (VFD) systems and large-scale server deployments.
