Quantity : 1 High-concerned chemical : none Package : SMD is_d : Yes Dissipation Power : PWM Fan Speed Motor Controller Board Supply Voltage : DC5-12V Application : Computer Type : Switch Brand Name : Gaqqee Origin : Mainland China Condition : New Operating Temperature : 0-50C wholesale : support dropshipper : support PWM fan controller : 12v pwm controller micro 5V PWM controller : pwm fan speed controller : 5v fan controller temperature fan controller 12v : fan pc potentiometer

Features: 1. Support DC5-12V wide voltage input range, suitable for a variety of different voltage requirements of the equipment, improve the flexibility of use 2. Fan speed control is realized through manual adjustment, which is more convenient to use. 3. Comes with a switch function, users can directly control the fan start and stop, convenient and efficient, effectively extend the life of the fan and equipment 4. Adopting advanced PWM speed control technology, which not only reduces the noise of the fan when running, but also maintains good heat dissipation at low speeds, creating a quieter working or living environment. 5. Four-wire interface compatible with mainstream chassis fans, easy to realize fan speed control Parameter: Operating voltage: DC5-12V can work in 5-15V voltage, please note that the fan voltage is consistent Fan current: not greater than 4A This current is limited by the switch and connector, you can go alone power line expansion Circuit board loss: not connected to the fan less than 20mA PWM signal mode: 5V20.5KHz for 12V power supply, 4V20.5KHz for 5V power supply. PWM signal output range: 1%-100 Output interface type: conventional CPU, chassis fan socket, pin spacing 2.54mm Circuit size: circuit board 22mm * 20mm, knob screw extends 15mm, mounting aperture 7mm Function Description: Pay attention to the positive and negative poles and power supply voltage, connect the power supply fan can be used, the potentiometer counterclockwise to the end of the closure, clockwise to the end of the maximum output. If the fan speed changes in the opposite direction of the adjustment direction, the fan is a reverse timing fan, you need to (PF) set point with a solder short, be sure to operate the first power off to avoid damage! After shorting, the PWM signal changes to the reverse direction with the adjustment, then the reverse timing fan can realize the forward adjustment. Attention: This is a four-wire PWM fan speed regulator, can only control the four-wire fan that supports PWM speed regulation, such as many 12V four-wire chassis or CPU fan, is not able to control 2-3 wire fan!!!! Default power-on PWM adjusts from 1%! Package include: Fan speed controller X1 label:yes
