Description
Sunon EEC0382B2-000U-A99 (also known as EEC0382B2000UA99) is an industrial-grade 2-phase, 4-pole brushless DC tubeaxial cooling fan measuring 120 x 120 x 38 mm (4.72 x 4.72 x 1.50 in). Operating on a nominal 24 VDC supply with an operating envelope of 10 to 27.6 VDC, it delivers a rated rotational speed of 2600 RPM, an airflow capacity of 116.0 CFM (197.1 m³/h), and a static pressure of 0.260 in H₂O (64.8 Pa) at an acoustic noise level of 44.0 dB(A). Built with UL 94V-0 flame-retardant thermoplastic PBT frame and blades, the unit features a long-life precision ball bearing system, internal reverse polarity protection, and automatic locked-rotor restart recovery.
Key Features
- Industrial Aerodynamic Output: Generates a robust 116 CFM airflow and 0.26 in H₂O static pressure for high-impedance electronics enclosures.
- Dual Ball Bearing Assembly: Precision engineered ball bearing system ensures a continuous operating service life exceeding 70,000 hours at 40°C.
- Wide Operating Voltage: Accommodates DC inputs from 10 to 27.6 VDC with low power draw and smooth starting performance.
- Integrated Circuit Protections: Features automatic locked-rotor restart recovery within ten seconds alongside full internal reverse polarity protection.
- Flame-Retardant Construction: Built with rugged UL 94V-0 thermoplastic PBT housing and impeller for demanding industrial thermal management.
