EFB1212ME, EFB1212HHE, EFB1248LE, EFB1212HE, EFB1224VHE specifications

Delta Electronics is known for its innovation and efficiency in the field of thermal management, primarily through its advanced cooling fan solutions. Among its array of products, the EFB series stands out with models such as the EFB1248SHE, EFB1248VHE, EFB1224ME, EFB1248HE, and EFB1212SHE. Each model boasts distinct features tailored to meet varying cooling requirements across different applications.

The EFB1248SHE operates on a voltage range of 48V and is designed to deliver an impressive airflow, making it suitable for high-performance computing environments. It is equipped with a ball bearing system that ensures longevity and reliability, crucial for mission-critical applications. The fan operates quietly, an essential characteristic for data centers where noise control is a priority.

Similarly, the EFB1248VHE model also utilizes a 48V power supply but offers a higher airflow capacity compared to the EFB1248SHE. This model is built to tackle the cooling needs of high-density server racks and other demanding applications. It features Delta's patented aerodynamic design, which enhances its performance while minimizing turbulence and noise.

The EFB1224ME model operates at 24V, providing versatility for designs that require lower voltage while still delivering considerable airflow. The fan is designed for effective thermal dissipation, ensuring that electronic components remain within optimal temperature ranges and enhancing overall system reliability.

On the other hand, the EFB1248HE is engineered for environments that require robust cooling capabilities. With advanced PWM control technology, this fan efficiently adjusts its speed based on thermal demand, resulting in energy savings and lower operating costs. The compact design and modular structure of the EFB1248HE allow for flexible integration into various systems.

Lastly, the EFB1212SHE operates at a lower voltage of 12V, making it ideal for applications where space is limited but cooling is still critical. With its lightweight design and effective airflow mechanics, this fan provides an excellent solution for consumer electronics and compact server systems.

In summary, Delta Electronics’ EFB series encompasses a range of models designed for superior cooling performance, reliability, and energy efficiency. With technologies like advanced aerodynamics, intelligent speed control, and durable bearing systems, these fans are ideal for high-demand applications across various industries, ensuring that electronic systems operate smoothly and efficiently.
