Description
The Sunon EEC0382B1-000U-A99 (also known as EEC0382B1000UA99) is a heavy-duty industrial DC brushless tubeaxial cooling fan engineered in a standard 120 x 120 x 38 mm (4.72 x 4.72 x 1.50 in) form factor. Powered by a 4-pole, 2-phase brushless DC motor running on 24 VDC, it delivers an aerodynamic airflow of 138.0 CFM (234.5 m³/h) with a maximum static pressure of 0.36 in H₂O (89.6 Pa) at 3100 RPM while consuming just 9.2 W. Built with flame-retardant UL 94V-0 PBT thermoplastic housing and impeller, the assembly utilizes a high-precision dual ball bearing system rated for 70,000 hours of continuous duty. Integrated electronics provide automatic locked-rotor restart recovery within 10 seconds alongside reverse polarity protection, with power delivered via 330 mm UL1007 24 AWG wire leads.
Key Features
- High-Flow Aerodynamics: Delivers 138.0 CFM of forced air and 0.36 in H₂O static head for dense electronic enclosures.
- Precision Ball Bearings: Heavy-duty dual ball bearing system provides 70,000 hours of continuous L10 service life at 40°C.
- Flame-Retardant PBT: Robust UL 94V-0 thermoplastic frame and impeller resist industrial thermal degradation and mechanical impact.
- Intelligent Motor Safety: Integrated automatic restart circuit resets within 10 seconds of rotor release, paired with polarity protection.
- Broad Voltage Window: Flexible 10 to 27.6 VDC input range accommodates industrial bus fluctuations with low 10 VDC starting threshold.
