Frequently Asked Questions

What is SUNON PMD1212PMB1-A?
PMD1212PMB1-A is a SUNON PMD-series DC brushless axial cooling fan featuring a nominal 120 x 120 x 38 mm frame, 12 VDC rated supply and precision dual ball bearing construction. The documented standard part number is PMD1212PMB1-A.(2).GN.

What is the rated voltage of PMD1212PMB1-A?
The manufacturer specifies 12 VDC for PMD1212PMB1-A.(2).GN. Its operating voltage range is 6-13.8 VDC, and the starting voltage is 6 VDC at 25°C.

What are the dimensions of PMD1212PMB1-A?
The nominal dimensions are 120 x 120 x 38 mm. The manufacturer drawing identifies a 120 ±0.5 mm square frame, 38 ±0.5 mm thickness, eight mounting holes with 4.3 ±0.3 mm diameter and 105 ±0.3 mm mounting-hole center spacing.

What is the rated current?
The exact manufacturer specification states 1600 mA, equivalent to 1.60 A, at the 12 VDC rated supply. SUNON specifies a tolerance of ±15% for rated current and power.

What is the power consumption?
SUNON specifies 19.2 W rated input power for PMD1212PMB1-A.(2).GN. A suitable DC power supply must account for the fan's electrical requirements and any additional equipment load.

What is the rated fan speed?
The manufacturer specifies 4200 RPM with a tolerance of ±10%. This is the documented performance rating for the PMD1212PMB1-A.(2).GN configuration.

What airflow does PMD1212PMB1-A provide?
The manufacturer specifies 190 CFM, approximately 322.8 m³/h. This is the free-air performance reference; actual airflow in an installed system depends on the resistance of the cooling enclosure and airflow path.

What is the maximum static pressure?
SUNON specifies 0.65 inH2O, approximately 161.9 Pa. The manufacturer catalog includes an airflow-versus-static-pressure characteristic curve for assessing system operating points.

What bearing system does PMD1212PMB1-A use?
The manufacturer specifies a precision dual ball bearing system. This bearing construction is documented for the standard PMD1212PMB1-A.(2).GN configuration.

What is the acoustical noise level?
SUNON specifies 54 dB(A). The manufacturer measures noise in a semi-anechoic environment with the fan operating in free air and the microphone positioned one meter from the intake. Actual installed noise may vary with airflow restrictions and mounting conditions.

How is PMD1212PMB1-A electrically connected?
The standard manufacturer specification shows two UL 1007 24 AWG DC power leads, with red positive and black negative. The mechanical drawing specifies a 300 ±10 mm lead length. The standard version does not provide a separate tachometer or PWM control wire. SUNON identifies optional R-Type rotation detector and F-Type frequency generator configurations with different part-number extensions.

What should be checked before ordering PMD1212PMB1-A?
Confirm the complete SUNON part number, including the (2).GN extension or any additional functional suffix, 12 VDC supply, 1.60 A rated current, 19.2 W power, 4200 RPM speed, 190 CFM airflow, 0.65 inH2O static pressure, precision dual ball bearings, 120 x 120 x 38 mm housing, 105 mm mounting-hole spacing, airflow direction and wire termination. PMD1212PMB2-A is a lower-speed 12 VDC version rated at 14.4 W and 170 CFM, while PMD2412PMB1-A requires 24 VDC. R-Type and F-Type configurations also differ electrically from the standard two-wire model. Verify mechanical, electrical and functional compatibility before selecting a replacement.
