12V PWM 4-Wire Temperature Control Speed Controller for PC Fan Chassis Cabinet Computer Fan Noise reduction

Note: This controller can only control the 12V standard 4-wire PWM fan and control the internal circuit speed of the 4-wire fan by outputting pwm signals without turning off the fan power without changing the fan voltage and cannot control 2-wire 3-wire and non-standard PWM fans

1. Input line: The red and black power cords are only welded with 12V positive and negative power cords for widely use
2. Temperature probe: The small black-headed wire is short and small and the heat capacity is low. It is suitable for testing narrow spaces and air temperature and the response is relatively fast. The ring probe is encapsulated in a ring metal head the ring diameter is 4.2mm suitable for screw mounting on the surface of the radiator or other heating objects.

Specification
Working voltage: DC12V can work in the range of 8-18V please pay attention to the fan withstand voltage
Current consumption: no more than 20mA
Fan interface: 2510-4P lacks 1 elbow (special interface for computer 4P fan)
Fan current: the interface can withstand 3A if you need to control a larger current fan please take the fan power cord separately
PWM output range: 10% -100
Working temperature: -10℃ to 60℃
Temperature probe parameters: NTC 50K B=3950
Probe temperature resistance: 120℃ for small black head 110℃ for ring probe
Board size: 34mm*19mm*11mm (excluding the extended interface) the fan interface extends 8mm
Factory default values ​​of the setting parameters: low speed 20% acceleration temperature 30°C acceleration width 5°C. Under this temperature setting holding the thermal probe with the palm of your hand will accelerate for a while and the probe will reach full speed within 2 minutes if it is clamped into the armpit.

This controller is designed as a combination of manual control and automatic temperature control:
1. It is purely manual when the temperature probe is not installed: single-click/double-click (the double-click speed should not be too fast) to increase/decrease the gear position. Each time you change the gear position and continue to run for 20 seconds the gear position will be automatically stored. Within 20 seconds the No. 2 indicator light will flash rapidly. When the flashing stops the gear position has been stored. When it is in a position where it cannot continue to increase/decrease the 3/1 indicator light will be on.
2. After installing the temperature probe use the manual speed adjustment speed as the initial low speed (bottom line speed). When the temperature exceeds the acceleration temperature the fan speed smoothly accelerates with the increase in temperature. When the temperature reaches or exceeds the sum of the acceleration temperature and the acceleration width (That is the temperature at full speed) the fan is at full speed.
