SUNON EEC0381B2-000U-A99 supports industrial equipment with DC brushless axial fan airflow. It is intended for installations where predictable air exchange is central to equipment stability.
A documented PWM input allows system demand to regulate speed, supporting part-load energy use and acoustic control. A smooth inlet and outlet transition reduces avoidable turbulence, helping preserve useful cooling capacity and manage installed sound.
System designers selecting EEC0381B2-000U-A99 should account for filter loading, then schedule replacement-fit checks in equipment qualification. This approach links equipment cooling needs with practical procurement and service decisions. Verify mounting, connector and airflow direction against the replacement space.
Stock and lead time can change. Confirm the exact suffix, quantity, and delivery date with the supplier before ordering.
The listed speed is 2600 rpm. Confirm frequency, control method, and duty point for the installed system.
Verify supply, wiring, obstructions, impeller movement, and protection status. Use the model datasheet before replacement or repair.
Yes. The worksheet lists up to 64.8 Pa; compare it with the system curve.
The worksheet lists 5.1 W input. Check supply capacity and operating conditions before commissioning.
It is listed for telecom cabinets, base stations, and network equipment. Check dimensions, airflow, pressure, and the installation environment against the actual equipment.

The 120 × 120 × 38 mm EEC0384B2-000U-A99 brings 48 VDC DC axial fan cooling to telecom cabinets, base stations, and network equipment. Up to 197.1 m³/h is its most prominent listed performance figure. Review its equipment fit during noise-control planning. Confirm environmental protection for the ordered version.
