PWM 4-Wire Fan Temperature Controller Speed Governor For PC Fan/Alarm DC 5V-12V
Popular

Product Introduction
Description
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'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 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
