Frequently Asked Questions

What is SUNON MF50151VX-B02U-G99?
MF50151VX-B02U-G99 is a SUNON MagLev-series DC centrifugal cooling blower. Commercial references describe a nominal 50 x 50 x 15 mm housing and a three-wire configuration, while an equipment safety report documents its 12 VDC, 2.04 W rating.

What is the rated voltage of MF50151VX-B02U-G99?
The complete model is listed at 12 VDC in DEKRA test report 3409237.50A and in several exact-model replacement listings. Its exact operating voltage range was not independently established.

What are the dimensions of MF50151VX-B02U-G99?
Exact-model suppliers identify 50 x 50 x 15 mm nominal dimensions. Because the centrifugal housing includes an outlet and mounting tabs, compare the installed blower's overall dimensions, mounting-hole positions and exhaust opening rather than relying on nominal size alone.

What is the rated current?
A supplier lists 0.17 A, or 170 mA. This is consistent with the independently documented 12 VDC and 2.04 W electrical ratings. A separate current rating in a complete SUNON B02U-G99 datasheet was not located.

What is the power consumption?
The documented value is 2.04 W. It appears in a DEKRA IEC 60335-2-29 equipment test report identifying the complete MF50151VX-B02U-G99 model, as well as in commercial replacement-part listings.

What is the rated fan speed?
One exact-model supplier specifies 6300 RPM. This is a supplier-reported speed, not a separately verified exact-model SUNON performance specification. The manufacturer catalog lists 6200 RPM for MF50151VX-1B00U-A99, which is a different configuration.

What airflow does MF50151VX-B02U-G99 provide?
The DEKRA safety test report lists 5.4 CFM, approximately 9.18 m³/h, for the complete model. Some sellers publish conflicting airflow figures. The 18.6 CFM figure sometimes associated with MF50151VX applies to a different axial fan configuration and should not be assigned to this centrifugal blower.

What is the maximum static pressure?
An exact-model static pressure rating was not independently verified. SUNON lists 0.97 inH2O for the related MF50151VX-1B00U-A99 blower, but that specification should not automatically be applied to B02U-G99.

What bearing system does MF50151VX-B02U-G99 use?
The V designation indicates SUNON's Vapo bearing system under the manufacturer blower model numbering scheme. The exact customer-specific bearing construction has not been separately confirmed in an individual B02U-G99 datasheet.

What is the acoustical noise level?
One exact-model supplier lists 33 dB(A), but an individual SUNON acoustic specification for B02U-G99 was not found. Related blower configurations may have different sound ratings, so the seller figure should be treated as provisional.

Does MF50151VX-B02U-G99 support speed feedback?
Yes. The manufacturer defines G99 as automatic restart with an F-type frequency generator output, and exact-model replacement suppliers describe a three-wire configuration with a yellow FG lead. The standard G99 code does not specify a dedicated PWM speed-control input. Confirm connector pin assignments, FG voltage levels and signal requirements before installation.

What should be checked before ordering MF50151VX-B02U-G99?
Confirm the complete SUNON MF50151VX-B02U-G99 part number, 12 VDC supply, 2.04 W rating, 0.17 A supplier-listed current, nominal 50 x 50 x 15 mm housing, mounting-tab positions, radial air outlet, three-wire connection, connector configuration and FG signal requirements. For a DeWALT DCB118 charger, check the charger type, production revision and existing fan assembly against the equipment service documentation. The related MF50151VX-1B00U-A99 centrifugal blower and MF50151VX-10000-G99 axial fan differ in electrical or airflow characteristics and should not automatically be substituted.
