Product Information

The SUNON KD4812PMB2-6A is a brushless DC axial fan for equipment that provides a compatible 48V DC cooling supply. Its 120mm square format and 38mm nominal depth make it suitable for consideration in replacement or new enclosure designs where the mechanical fit, power rating and airflow requirement agree with the equipment specification.

At its rated operating point, the catalogue lists 2800rpm, 127CFM airflow, 0.28 inch H₂O static pressure and 7.7W power consumption. Airflow and maximum static pressure describe different ends of the fan performance range; they are not delivered simultaneously. Restrictive vents, filters and close obstructions affect the airflow obtained after installation.

Check the complete label and lead or connector arrangement on the supplied unit against the equipment before installation, including the required polarity. This fan requires 48V DC and must not be connected directly to AC mains. No PWM control, speed-feedback output or specific mating connector is promised for this listing. A power supply, adapter, guard and installation hardware are not documented as included; arrange compatible accessories separately as needed.
