The product will be upgraded constantly, the appearance and color may be changed, please don`t mind. And take a consideration before place the order if you have request for color or appearance.
Metal fan blade blower, rated voltage is DC36V high power 25W. But this fan needs two sets of power supply to run, the red wire is for power supply to the control IC (+5V), the brown wire is for power supply to the motor, (+12V)-(+36V), the black wire is for the second power supply The common negative pole of , and the white line is the feedback signal FG, which can be left unconnected.
Note: The red wire is connected to +5V, the brown wire is connected to +36V, and the black wire is the common negative pole of the two sets of power supplies. The voltage of the red wire is strictly prohibited to exceed +5V, and the positive and negative poles are strictly prohibited.
Brown wire: +36V, the main power supply for the motor
Red line: +5V, is the power supply to the control IC
Black line: the common negative pole of the two groups of power supplies
White line: FG, feedback signal, no wiring if left open.
Note: The voltage of the red wire is strictly prohibited to exceed 5V, the brown wire is the positive pole of the motor power supply, the applicable voltage is (+12V)-(+36V), the black wire is the common negative pole of the two sets of power supplies, and the positive and negative poles are also strictly prohibited to be wrongly connected. Wrong wiring will burn the driver board.
This fan can adjust the main power voltage of the motor (DC12V-36V), and the voltage regulation can adjust the speed of the motor, that is, adjust the air volume of the fan. But there is another way, the voltage of the motor remains the same, that is to adjust the baffle, and use the baffle to block the size of the air inlet to change the air output of the fan. The smaller the air inlet, the smaller the air volume.
Fan weight: 780 grams
We adjust the air inlet to the maximum, then adjust the voltage of the motor (brown line), and measure the current of the fan at different voltages:
Voltage: DC12V, Current: 0.5 A
Voltage: DC24V, Current: 1.05 A
Voltage: DC36V, Current: 1.6 A
Reminder: the red wire is for power supply to the control IC, the voltage is +5V, the brown wire is for power supply to the motor, the voltage is +36V, the black wire is the common GND of the two groups of power supplies, it is strictly forbidden to connect the wrong wire, it will burn Bad driver board.
