THB1548EG-00V5A Delta

Description

The Delta Electronics THB1548EG-00V5A is an ultra-high-performance 48VDC axial fan with dimensions of 172 x 150 x 51 mm, specifically engineered for extreme thermal management in high-density industrial and telecommunications infrastructure. As part of the THB high-static pressure series, this side-cut round frame fan features a robust aluminum housing and a specialized high-speed impeller (UL 94V-0), optimized for maximum aerodynamic throughput and superior pressure resistance. It operates at a rated speed of 7,500 RPM, delivering a massive air flow of 524.37 CFM (890.3 m³/h) and a peak static pressure of 3.047 inH₂O (758.8 Pa). Equipped with a precision dual ball bearing system and PWM control functionality, the THB1548EG-00V5A ensures a reliable service life under demanding conditions. This model is characterized by its exceptional power-to-airflow ratio and integrated speed monitoring, making it a critical component for 5G base stations, server storage systems, and high-wattage industrial power conversion units.
