5V12V/12V 4-wire /2-3wire PWM fan temperature control speed controller DIYReference description:
5V12V 4-wire PWM fan temperature control speed controller
note:
1. This controller can only control 5V or 12V standard 4-wire PWM fan. The fan speed is controlled by PWM signal, and the actual speed of the fan is affected by the wind.
The design influence of the fan itself. Can't adjust the speed of 2-3 wire ordinary fan, can't cut off the power of the fan, can't turn off the fan completely.
2. Please note that the power supply voltage must match the fan voltage.
Basic parameters:
Working voltage: DC5V or 12V (board working range DC4.5-16V)
Control the fan current: the plug-in board does not exceed 3A (a larger current fan can be achieved through an external power cord)
Circuit self-consumption: no more than 20mA
PWM signal mode: 25KHZVpp=3.3V
Temperature probe model: 50KB=3950
Circuit operating temperature: -10℃ to 60℃
Probe temperature resistance: small black head 120°C ring probe 110°C
Board size: 29mm*13mm*9mm (without interface), the fan interface extends 7mm and can be sleeved with a diameter of 12 heat shrinkable tube
Factory default setting: basic speed control output Po=20%, acceleration temperature Tu=30℃, temperature control interval Td=5℃ (35℃ full speed), signal forward mode.
note:
1. The pin current on the board should not exceed 3A
2. The controller does not participate in speed measurement
3. The controller does not control the fan power
Signal mode setting instructions:
Forward mode: used for conventional fans, PWM positive changes, full output value is 100
Reverse mode: used for conventional reverse timing fan, PWM reverse change, full output is 0
Reverse 80% mode: for special reverse timing fans, reverse change, full output is 20
12V 4-wire PWM fan temperature control speed controller
Product introduction:
note:
1. This controller can only control the 12V standard 4-wire PWM fan, and control the fan speed through the PWM signal. The actual speed of the fan is set by the fan itself.
计impact. Can't adjust the speed of 2-3 wire ordinary fan.
2. This controller participates in power supply control, and the circuit cannot be connected with reversed polarity! If the connection is reversed, the circuit board safety bit "F" position may be burnt
Basic parameters:
Working voltage: DC12V (board working range DC9.5-15V)
Control fan current: no more than 1.2A (larger current fan can be controlled by external relay)
Circuit self-consumption: no more than 20mA
PWM signal mode: 25KHZVpp=5V
Temperature probe model: 50KB=3950
Circuit operating temperature: -10℃ to 60℃
Probe temperature resistance: small black head 120°C ring probe 110°C
Board size: 36mm*13mm*9mm (without interface), the fan interface extends 7mm
Factory default settings: basic speed control output Po=20%, acceleration temperature Tu=30°C, temperature control interval Td=5°C (35°C full speed), Tu-2°C (28°C) to stop the fan, signal
Forward mode.
note:
1. The fan current cannot exceed 1.2A
2. The controller does not participate in speed measurement
Signal mode setting instructions:
Forward mode: used for conventional fans, PWM positive changes, full output value is 100
Reverse mode: used for conventional reverse timing fan, PWM reverse change, full output is 0
Reverse 80% mode: for special reverse timing fans, reverse change, full output is 20
Board working voltage range: DC9.5-15V
Abnormal status indication:
No output "1" light flashes quickly: power supply voltage is too low
No output "3" light flashes quickly: power supply voltage is too high
2-3 wire can shut down 5V-12V fan temperature control speed controller
Product introduction:
note:
1. This controller supports 2-3 wire fan temperature control and speed regulation with DC 5V-12V current not exceeding 0.9A, through smooth voltage reduction control, and supports low temperature shutdown of the fan power.
2. Please note that the power supply voltage must match the fan voltage!
3. For wiring, please pay attention to the positive and negative polarity of input! If the connection is reversed, the circuit board "FUSE bit" may be burnt
Basic parameters:
Working voltage: DC5-12V (board working range DC4.6-13.5V, over-range protection)
Control fan current: 0.1-0.9A (lower than 0.1A fan control effect is poor)
Circuit self-consumption: 10-30mA
Temperature probe model: 50KB=3950
Circuit operating temperature: -10℃ to 60℃
Probe temperature resistance: small black head 120°C ring probe 110°C
Board size: 54mm*13mm*8mm (without interface), the fan interface extends 7mm
Factory default settings: basic speed control output Po=35%, acceleration temperature Tu=30°C, temperature control interval Td=5°C (35°C full speed), and the fan does not shut down when the temperature is low.
note:
1. The fan current cannot exceed 0.9A
2. The controller does not participate in speed measurement
3. Do not connect the reverse polarity!!
Board working voltage range: DC4.5-13.5V
Abnormal status indication:
No output "1" light flashes quickly: power supply voltage is too low
No output "3" light flashes quickly: power supply voltage is too high
