Frequently Asked Questions

What is SUNON MEC0251V1-000U-A99?
MEC0251V1-000U-A99 is a SUNON MagLev MEC-series brushless DC axial cooling fan featuring a 120 x 120 x 25 mm housing, 12 VDC rated voltage and precision Vapo bearing system.

What is the rated voltage of MEC0251V1-000U-A99?
The manufacturer specifies 12 VDC, with an operating voltage range of 6-13.8 VDC and a starting voltage of 6 VDC at 25°C.

What are the dimensions of MEC0251V1-000U-A99?
The nominal dimensions are 120 x 120 x 25 mm. SUNON's mechanical drawing specifies a frame width of 120 ±0.5 mm and a mounting-hole center spacing of 105 ±0.3 mm.

What is the rated current?
The exact-model SUNON specification identifies 451 mA rated current and 519 mA maximum current. Some distributor specifications use rounded current figures.

What is the power consumption?
SUNON specifies 5.4 W rated power consumption and 6.22 W maximum power consumption. Some distributors round the rated power to 5.5 W.

What is the rated fan speed?
The manufacturer specifies 3100 RPM with a tolerance of ±10% at the rated supply voltage.

What airflow does MEC0251V1-000U-A99 provide?
The SUNON manufacturer datasheet specifies 108.2 CFM, approximately 183.8 m³/h, under its published performance test conditions.

What is the static pressure rating?
The maximum static pressure is 0.28 inH2O, equivalent to approximately 69.7 Pa.

What bearing system does MEC0251V1-000U-A99 use?
The manufacturer specifies a precision Vapo bearing system within the SUNON MagLev product range.

What is the acoustical noise level?
The manufacturer specifies 44.5 dB(A). Actual noise in an installed enclosure may vary because of mounting conditions, airflow restriction and surrounding equipment.

How is MEC0251V1-000U-A99 electrically connected?
The manufacturer drawing specifies two DC power leads using UL 1007 24 AWG wire. Red is positive and black is negative, with a specified lead length of 330 ±15 mm. The standard two-wire configuration does not provide a separate PWM control or tachometer lead. SUNON advises against using power-line or ground-line PWM speed control.

What should be checked before ordering MEC0251V1-000U-A99?
Confirm the complete SUNON model number, 12 VDC supply, 0.451 A rated current, 5.4 W power consumption, 120 x 120 x 25 mm dimensions, 105 mm mounting-hole spacing, Vapo bearing, two-wire electrical connection, lead polarity, airflow direction and cooling requirements. Do not automatically substitute MEC0251V2-000U-A99, MEC0252V1-000U-A99 or other MEC-series versions without checking their electrical, performance and mechanical specifications.
