5. Taidacent 2510-4P 3P Manual 4 Wires 0-5V 12V Fan Speed Controller PWM Speed Control On Off Switch for PC CPU Case Fan with Knob (Solder Connector with Plastic Black Knob)
Key Features:
- This is a four-wire PWM fan speed controller. It can only control 12V four-wire fans that support PWM speed regulation. For example, many 12V four-wire chassis or CPU fans cannot control 2-3-wire fans.
- If the speed of the fan changes and the direction of adjustment is opposite, it means that the fan is a reverse-sequence fan, and the (PF) setting point needs to be short-circuited with solder, and the power must be turned off before operation to avoid damage! The short-circuited PWM signal changes in the reverse direction with the adjustment, and the reverse-sequence fan can realize forward adjustment.
- Pay attention to the positive and negative poles and the power supply voltage. After the power supply fan is connected, it can be used. The potentiometer is turned off counterclockwise to the end, and the clockwise end is the maximum output. A separate small adjustable resistor (starting speed adjustment) on the board is used to adjust the speed of the just-open position.
- Fan current 3A this current is limited by switches and connectors, and the capacity can be expanded by taking the power line separately. For fans over 3A, connect a large current fan method: the positive and negative poles of the power supply of the fan can be connected to the power supply, the positive and negative poles of the fan are connected to the power supply separately, and the negative pole of the fan is connected to the negative pole of the board; speed measurement and control are connected to the board .
- Consumption less than 20mA without fan PWM signal model 0-5V 25Khz PWM signal output range 0% to 100% Start of PWM adjust range 0% to 60% Output interface 2510-4P, 2.54mm space Size 26*20mm, knob screw extension 15mm installation opening 7mm
