Product Feature:
1. The product is made of high-quality materials with guaranteed quality
2. Ultra small size design, 12V four wire PWM fan intelligent temperature control governor that can forcibly shut down the fan
3. MCU control, accurate setting, automatic saving, support for manual operation
4.49 temperature zone combinations, 3 shutdown modes, and 3 signal modes
5. Stable product performance and long service life
Product Introduction:
1. This controller can only control a 12V standard 4-wire PWM fan. The fan speed is controlled through PWM signals, and the actual speed change of the fan is affected by the fan's own design. Unable to adjust speed for 2-3 wire ordinary fans
2. This controller is involved in power control, and the circuit cannot be connected in reverse! If connected in reverse, it may burn out the fuse position "F" on the circuit board
Product parameters:
Working voltage: DC12V (board working range DC 9.5-15V)
Control fan current: not exceeding 1.2A (larger current fans can be controlled through external relays)
Circuit self consumption: not exceeding 20mA
PWM signal mode: 25KHZ Vpp=5V
Temperature probe model: 50K B=3950
Circuit operating temperature: -10 ℃ to 60 ℃
Probe temperature resistance: small black head 120 ℃ circular ring probe 110 ℃
Board size: 36mm * 13mm * 9mm (excluding interface), fan interface extends 7mm
Factory default settings: Basic speed regulation output Po=20%, acceleration temperature Tu=30 ℃, temperature control range Td=5 ℃ (35 ℃ full speed), Tu-2 ℃ (28 ℃), fan shutdown, signal forward mode
Note:
1. The fan current should not exceed 1.2A
2. The controller does not participate in speed measurement
Explanation of signal mode setting:
Forward mode: used for conventional fans, with PWM forward variation and a full output value of 100
Reverse mode: used for conventional reverse timing fans, PWM changes in reverse, with a full output of 0
Reverse 80% mode: used for special reverse timing fans, with reverse variation and a full output of 20
Board working voltage range: DC9.5-15V
Abnormal status indication:
No output "1" light flashing quickly: the power supply voltage is too low
No output "3" light flashing fast: power supply voltage too high
