EFB0812EH-R00 Delta 12V 0.42A 80x80x25mm DC Axial Fan

Description

The Delta EFB0812EH-R00 is a high-performance 80 mm DC axial fan designed for intensive thermal management in server environments and industrial automation. Operating on a 12 VDC supply, this unit is characterized by a high-torque motor drawing 0.42 A, enabling it to maintain a stable speed of 5000 RPM under significant system backpressure. The -R00 specification features a dedicated three-wire configuration with an integrated Locked Rotor Sensor, providing a critical diagnostic signal for system safety monitoring. Built with a dual ball bearing system and UL 94V-0 flame-retardant materials, the EFB0812EH-R00 ensures long-term reliability and high airflow efficiency. Its robust construction and standardized 80 x 80 x 25.4 mm dimensions make it an ideal replacement and OEM component for mission-critical networking hardware and power supply cooling systems across an ambient temperature range of -10 °C to +70 °C.
