DC 5V 12V PWM Temperature Controller Denoised Speed Controller Governor Board Module ON/OFF For PC Fan/Alarm With Wire Cable

Description: note: 1. This controller can only control 5V or 12V standard 4-wire PWM fans. The fan speed is controlled by PWM signal. The actual speed of the fan is affected by the design 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: DC 5V or 12V (board working range D.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: 25KHZ Vpp=3.3V Temperature probe model: 50K B=3950 Circuit operating temperature: -10℃ to 60℃ Probe temperature resistance: small blackhead 120℃, ring probe 110℃ 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 Description: 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 change of the fan is affected by the design of the fan itself. Can't adjust the speed of 2-3 wire ordinary fan. 2. This controller participates in power control, and the circuit cannot be connected to the reverse polarity! If the connection is reversed, the circuit board safety bit "F" position may be burnt Basic parameters: Working voltage: DC 12V (board working range DC 9.5-15V) Control fan current: no more than 1.2A (larger current fan can be controlled by external relay) Circuit consumption: no more than 20mA PWM signal mode: 25KHZ Vpp=5V Temperature probe model: 50K B=3950 Circuit operating temperature: -10℃ to 60℃ Probe temperature resistance: small blackhead 120℃, ring probe 110℃ 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 turn off 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 Description: 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. Please pay attention to the positive and negative polarity of the wiring! If the connection is reversed, the circuit board "FUSE bit" may be burnt Basic parameters: Working voltage: DC 5-12V (board working range D.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: 50K B=3950 Circuit operating temperature: -10℃ to 60℃ Probe temperature resistance: small blackhead 120℃, ring probe 110℃ 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 operating voltage range: D.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 About shipping
