Frequently Asked Questions

What is SUNON MEC0381V1-000U-A99?
MEC0381V1-000U-A99 is a SUNON MagLev MEC-series brushless DC axial cooling fan with a 120 x 120 x 38 mm housing, 12 VDC rated voltage and precision Vapo bearing system.

What is the rated voltage of MEC0381V1-000U-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. The connected power supply should meet the equipment's electrical requirements.

What are the dimensions of MEC0381V1-000U-A99?
The nominal dimensions are 120 x 120 x 38 mm. The manufacturer drawing specifies a 120 ±0.5 mm square frame, 38 +0.5/-0 mm thickness and eight 4.3 ±0.3 mm mounting holes with 105 ±0.3 mm center spacing.

What is the rated current?
The exact SUNON manufacturer specification states 833 mA rated current and 958 mA maximum current at the specified operating conditions.

What is the power consumption?
SUNON specifies 10.0 W rated power consumption and 11.50 W maximum power consumption. Some distributor listings display different power values; the manufacturer's exact-model specification D12017130G-05 is the reference used here.

What is the rated fan speed?
The manufacturer specifies 3100 RPM with a tolerance of ±10% at the rated supply voltage. This is the documented high-speed V1 configuration within the MEC0381 series.

What airflow does MEC0381V1-000U-A99 provide?
SUNON specifies 138 CFM, approximately 234.5 m³/h, under its published airflow test conditions. The operating airflow inside equipment depends on the resistance of the ventilation path.

What is the maximum static pressure?
The manufacturer specifies 0.36 inH2O, approximately 89.7 Pa. The applicable manufacturer catalog includes an airflow-versus-static-pressure curve for evaluating system cooling requirements.

What bearing system does MEC0381V1-000U-A99 use?
The fan uses SUNON's precision Vapo bearing system. The manufacturer identifies a 70000-hour life expectancy at 40°C, 65% relative humidity and a 90% confidence level under laboratory reliability test conditions. This figure is not an unconditional service-life guarantee.

What is the acoustical noise level?
The exact manufacturer specification identifies 48 dB(A). SUNON measures fan noise under free-air conditions in a semi-anechoic chamber with a microphone positioned one meter from the fan intake. Noise in an installed enclosure may differ.

How is MEC0381V1-000U-A99 electrically connected?
The manufacturer drawing specifies two UL 1007 24 AWG DC power leads, red positive and black negative, with a wire length of 330 ±15 mm and a stripped end length of 5 ±0.3 mm. The standard A99 configuration has no dedicated PWM or speed-feedback lead. The manufacturer advises against PWM switching of the power or ground connection. Automatic restart and polarity protection are included.

What should be checked before ordering MEC0381V1-000U-A99?
Confirm the complete SUNON model number, 12 VDC supply, 833 mA rated current, 10 W rated power, 3100 RPM speed, 138 CFM airflow, 0.36 inH2O static pressure, Vapo bearing system, 120 x 120 x 38 mm frame, 105 mm mounting-hole center spacing, airflow direction and two-wire electrical connection. MEC0381V2-000U-A99 and MEC0381V3-000U-A99 have lower speeds and different airflow and power ratings. MEC0382V1-000U-A99 requires 24 VDC, while EEC0381B1-000U-A99 uses dual ball bearings. These models should not automatically be substituted without confirming electrical, mechanical and cooling-performance compatibility.
