 Note: This is a four-wire PWM fan controller, which can only control fans that comply with Intel’s four-wire fan specifications (most 12-48V four-wire fans are supported), and cannot control 2-3-wire fans and cannot be completely turned off. Turn off the fan.
Features:
- DC8-60V ultra-wide working voltage range (here refers to that the control board can work within this voltage range. In actual work, the controller power supply and the fan are together, so the power supply must be by the fan power supply requirements, otherwise the fan will be damaged).
-  Two-channel independent temperature control, which alternately displays the temperature of the two channels (-9.9°C to 70.1°C, error <1°C) and fan speed (resolution 10rpm, maximum display 999*10rpm, always display 999 after exceeding).
- The minimum speed of the fan and the temperature control zone are set by buttons, which are flexible in control and have a large setting range. The program is saved after setting.
- The stop alarm function of the switch can be set (the external AC buzzer beeps for a long time, the default is off)
- Control ability: Not limited by the fan current, but the maximum current of the fan interface pins on the board should not exceed 3A. If you use a larger current fan, please connect the fan power cord directly to the main power supply.
- Control output range: 10%-100% (this is only the signal output range, the actual situation depends on the fan performance)
- Rotation speed measurement: 10-9990 rpm, greater than this speed will always display 999, resolution 10 rpm, display unit *10 rpm (speed measurement is based on the common 2-pole signal fan design, most fans are 2-pole signals)
- Stop alarm speed: lower than 375rpm
- Circuit size: 65mm*65mm*15mm; center distance of positioning hole 56mm*56mm; diameter 3.2mm
