Frequently Asked Questions

What is SUNON KDE1212PMS1-6A?
KDE1212PMS1-6A is a SUNON traditional KDE-series brushless DC axial cooling fan with a nominal 120 x 120 x 38 mm frame, 12 VDC rated supply and lubricated sleeve bearing. Its published rated power is 6.8 W.

What is the rated voltage of KDE1212PMS1-6A?
The SUNON KDE catalog specifies 12 VDC. A distributor lists an operating voltage range of 10.2-13.8 VDC. An older manufacturer specification for the related KD1212PMS1-6A identifies an 8 VDC starting voltage, but that starting value was not independently confirmed for the exact KDE designation.

What are the dimensions of KDE1212PMS1-6A?
SUNON's KDE catalog lists nominal dimensions of 120 x 120 x 38 mm. A related KD1212PMS1-6A manufacturer drawing shows a 119.5 ±0.5 mm square housing and 38.5 ±0.5 mm depth. These detailed measurements belong to the KD-labeled document, so exact KDE mechanical tolerances should be confirmed when replacement fit is critical.

What is the rated current?
The KDE manufacturer series catalog and supporting distributor data specify 0.57 A, or 570 mA, for KDE1212PMS1-6A. The related KD model has the same published current rating.

What is the power consumption?
The published input power is 6.8 W at 12 VDC. The rating appears in SUNON's KDE Traditional System Motor catalog and is independently repeated in distributor references for the model.

What is the rated fan speed?
SUNON specifies 3000 RPM. The related KD1212PMS1-6A datasheet and distributor information indicate a rated-speed tolerance of ±250 RPM. Other versions such as KDE1212PMS2-6A and KDE1212PMS3-6A have different rated speeds.

What airflow does KDE1212PMS1-6A provide?
The SUNON manufacturer catalog specifies 107 CFM, approximately 181.8 m³/h. This is a catalog performance value; actual airflow in equipment depends on the ventilation path and system resistance.

What is the maximum static pressure?
The published maximum static pressure is 0.30 inH2O, approximately 74.7 Pa. The fan should be selected by comparing its airflow and pressure characteristics with the cooling system's operating requirements.

What bearing system does KDE1212PMS1-6A use?
The fan uses a lubricated sleeve bearing, as identified in the SUNON KDE catalog and the related manufacturer specification. The KDE1212PMB1-6A is a different dual-ball-bearing version and has different speed, airflow, pressure and noise values.

What is the acoustical noise level?
SUNON's catalog specifies 41 dB(A). The related KD manufacturer specification describes free-air acoustic testing in a semi-anechoic chamber with a microphone positioned one meter from the fan intake. Installed equipment noise may differ.

How is KDE1212PMS1-6A electrically connected?
Exact-model commercial listings describe a two-wire fan. A related KD manufacturer drawing specifies UL 1007 24 AWG leads with red positive and black negative wiring. A KDE-series distributor references approximately 300 mm leads. Because connector details and exact lead length were not independently established from an individual KDE datasheet, verify the actual fan assembly and equipment wiring before connection.

What should be checked before ordering KDE1212PMS1-6A?
Confirm the complete SUNON KDE1212PMS1-6A model number, 12 VDC supply, 0.57 A rated current, 6.8 W power consumption, 3000 RPM speed, 107 CFM airflow, 0.30 inH2O static pressure, lubricated sleeve bearing, nominal 120 x 120 x 38 mm dimensions and two-wire electrical connection. Also verify the mounting-hole pattern, lead length, connector termination and airflow direction. KDE1212PMS2-6A and KDE1212PMS3-6A have lower speed and airflow ratings. KDE1212PMB1-6A uses a ball bearing system, and KDE2412PMS1-6A requires 24 VDC. The similar KD1212PMS1-6A designation shares key published performance values but should not automatically be treated as an identical mechanical part without inspection and specification matching.
