PWM 4-Wire Fan Temperature Controller 25KHZ Vpp=3.3V For PC Fan

Description: Product Description If you have any questions, please contact customer service first, do not open disputes easily, thank you! Features: 1.The product can only control 5V or 12V standard 4-wire PWM fan, through the PWM signal to control the fan speed, the actual fan speed change by the fans own design. 2. The product can not speed control 2-3 wire ordinary fan, can not cut off the fan power supply, can not completely shut down the fan. 3. Default settings: basic speed control output Po = 20%, acceleration temperature Tu = 30 ℃, temperature control interval Td = 5 ℃ (35 ℃ full speed), signal positive mode. 3. Please note: The power supply voltage should match the fan voltage. The control and speed measurement wires of the fan should not be connected to the positive pole of the power supply! Otherwise it is easy to cause the product short-circuit burned out! Specification: Control fan current: plug board not more than 3A(Higher current fan available with external power cord) Working voltage: DC 5V or 12V Board operating range: DC 4.5-16V Circuit self-consumption: <20mA PWM signal mode: 25KHZ Vpp=3.3V Temperature probe type: 50K B=3950 Circuit operating temperature: -10 ℃ to 60 ℃ Probe temperature resistance: 120℃ Board size: 29mm*13mm*9mm Package Includes: 1*Governor 1*Probe Note: 1. Please allow 1-3 mm error due to manual measurement. Please make sure you dont mind before ordering. 2. Please allow 1-3g weight error. Please make sure you dont mind before ordering. 3.
