Product Description
DC 12V 24V Fan Stepless Speed Regulation Board PWM Temperature Control Speed
The main performance characteristics of this governor:
1. Double temperature probe, two independent temperature detection and speed regulation,
which do not affect each other.
2. Suitable for all types of 12V/24V-2, 3, 4 wire fans.
3. The temperature sensor has an extension cable, which is more convenient to use and
more sensitive to control.
4. Fixed mode: the starting temperature is fixed at 30 degrees, and the full temperature
is 50 degrees.
5. Adjustable mode: The starting temperature can be adjusted to 10 degrees at the lowest,
and the maximum can be adjusted to 50 degrees (full speed temperature = starting
temperature +20 °C)
6. Industrial design, suitable for a variety of complex industrial / outdoor environments
7. Super power, each fan can be connected to 5A current
8. Ultra-low power consumption, the value of the power consumption is <0.1 watt. When the
fan is turned off, the governor only consumes 0.006A current, which greatly saves energy.
Special Note: The maximum temperature of the temperature probe is 110 degrees. Above this
temperature, the probe will be damaged! !
Wiring port:
No. 1 (12+): DC 12V/24V power positive terminal
No. 2 (12-): DC 12V/24V power supply negative wiring port
No. 3 (Fan1+): The first DC fan positive terminal port
No. 4 (Fan1-): The first DC fan negative wiring port
No. 5 (Fan2+): The second DC fan positive terminal port
No. 6 (Fan2-): second DC fan negative wiring port
The position marked on the 7th is the temperature sensor interface No. 2.
The position marked on the 8th is the temperature sensor interface No. 1.
The 9th position is the LED indicator: POW is the power light, L1 is the first working
indicator of the fan, and L2 is the working indicator of the second fan.
About the potentiometer at position 10:
No. 10 is the temperature adjustment potentiometer. When the governor works in the
adjustable mode, turn this potentiometer to adjust the fan start & full speed
temperature.
(W1 adjusts the first temperature control, W2 adjusts the second temperature control)
When the governor is shipped from the factory, the default setting is fixed temperature
mode, that is, the governor is fixed to 30 degrees to start the fan, and the 50 degree
fan is full speed.
If you need to use the temperature adjustable mode, you need to open the outer casing of
the governor and turn the switch to the A position (S1 corresponds to the first
temperature control and S2 corresponds to the second)
Instructions
1. Connect the power supply and fan wiring according to the interface description.
2. Plug the temperature probe into the governor and fix the metal part of the probe to
the hot part.
3. Turn on the power, the governor will adjust the fan speed according to the temperature
detected by the temperature probe.
4. Use of fixed mode and adjustable mode
4.1: Fixed mode, when the speed switch is in the F position, the temperature range of the
governor is fixed at 30 low speed start fan, 50 degree fan full speed, at this time
adjusting the 10th potentiometer is useless
4.2: Adjustable mode, the speed switch is in the A position, and the temperature range of
the governor is set by the potentiometer No. 10
4.2.1: At the time of shipment, the potentiometer of No. 10 has been adjusted to the
position of the minimum starting temperature (10 degrees, the corresponding full speed
temperature is 30 degrees)
Slowly rotate the potentiometer of No. 10 clockwise, the temperature range of the
governor will increase slowly. After one rotation, the starting temperature of the
governor will change to 50 degrees, and the corresponding full speed temperature is 70
degrees.
This governor has a maximum drive current of 5A, which means it can be connected to two
5A fans at the same time.
When multiple fans need to be connected, as long as the total current of the connected
fans is less than 5A, there is no limit!
Application range:
This governor is fully industrial-grade and suitable for industrial and outdoor
environments.
1. Energy saving and noise reduction of outdoor chassis and cabinet fans
2. Machine room fan energy saving noise reduction
3. Desktop computer\assembly machine fan noise modification
4. Other temperature control speed application
Size: 9.5*5*3CM
