Description

DC 5V/12V 4 Wire PWM Computer CPU Fan Temperature Speed Controller Module 40cm Ring/10cm Dot Temperature Sensor Probe

Note:

1. This controller can only control 5V or 12V standard 4-wire PWM fans. The fan speed is controlled by PWM signals. The actual speed change of the fan is affected by the design of the fan itself. Can not adjust the speed of 2-3 wire ordinary fan, can not cut off the fan power, can not completely turn off the fan.

2. Please note that the power supply voltage must match the fan voltage.

Parameter:

Working voltage: DC 5V or 12V (board working range DC 4.5-16V)

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 cannot 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

Package Included:

1 * DC 5V/12V PWM Fan Controller Module Temperature Sensor Probe
