What is ADDA AD0612LB-D9B?
ADDA AD0612LB-D9B is a 12 VDC brushless axial cooling fan with a 60 x 60 x 15 mm frame, dual ball bearing design, PWM input and FG output.
What voltage does AD0612LB-D9B require?
The manufacturer specifies a nominal voltage of 12 VDC and an operating voltage range of 11.4-12.6 VDC.
What are the dimensions of AD0612LB-D9B?
The fan frame measures 60 x 60 x 15 mm, with 50 x 50 mm mounting-hole spacing and 4.4 mm mounting holes according to the manufacturer drawing.
What is the rated current and power consumption?
The datasheet specifies 0.12 A rated current and 1.44 W rated power at 100% duty cycle. It separately lists 0.07 A measured current and 0.84 W measured power.
What is the rated fan speed?
The manufacturer specifies 3500 RPM ±10% at the rated voltage and 100% PWM duty cycle.
What is the airflow rating of AD0612LB-D9B?
The specified free-air flow is 16.990 CFM, equivalent to 0.480 m³/min. Airflow in an installed enclosure depends on system resistance.
What is the static pressure rating?
The manufacturer specifies 0.087 inH2O, equivalent to 2.209 mmH2O, under the stated test conditions.
Does AD0612LB-D9B support PWM speed control?
Yes. The manufacturer datasheet documents a blue PWM input with a 30%-100% operating duty cycle range. It states that the fan runs at rated speed if no PWM signal is connected.
Does the fan provide a speed-monitoring output?
Yes. The documented four-wire configuration has a white FG signal lead for speed monitoring, alongside red positive, black negative and blue PWM leads.
What bearing type does AD0612LB-D9B use?
The manufacturer specification identifies a dual ball bearing system. The documented operating temperature range is -10°C to +70°C.
What is the specified noise level?
The ADDA datasheet lists a nominal noise level of 28.5 dB(A), with a specified maximum of 32.5 dB(A), measured under the manufacturer test conditions.
What should be checked before ordering AD0612LB-D9B?
Confirm the full model number, 12 VDC power supply, 60 x 60 x 15 mm dimensions, mounting holes, four-wire arrangement, PWM and FG connections, and airflow requirements. Compare the supplied fan configuration with the equipment wiring because product listings may describe different wiring variants.
