Parameters: Operating Voltage: DC 12V 24V Adjustment Method: Temperature-controlled speed regulation Maximum Output Current: 5A

Product Introduction: This speed controller supports 12V/24V 5A input (current determined by interface current carrying capacity), one input and three synchronous outputs, compatible only with Intel standard 4-wire fans (2/3-wire fans are not usable). It uses pure PWM signal speed control to avoid stuttering and abnormal noise caused by power interruption. When the blue wire is connected to the negative terminal, the fan speed is at its minimum (approximately 20%, does not shut off).

Instructions for Use: This speed controller is designed to enter minimum speed at around 23℃. The maximum speed is set between 43-70℃ via a DIP switch. With all DIP switches off, the maximum speed is 43℃, and the fan operates continuously between 23-43℃. With the first switch in the ON position, the maximum speed is 52℃, and the fan operates continuously between 23-52℃. With the first switch off and the second switch on, the maximum speed is 61℃, and the fan operates continuously between 23-61℃. With both switches on, the maximum speed is 70℃, and the fan operates continuously between 23-70℃.
