Power supply voltage: DC11-55V (circuit operating voltage) Working current: Less than 0.1A Fan current: Less than 5A (on-board connector withstand capability, if you need to control higher power, you only need to take the power cord separately) PWM range: 5-100 or 0 (% plus or minus 0.3%) PWM frequency: 20KHz or 2.5KHz (±2%) PWM signal amplitude: 10.5V (no load) Temperature measurement range: -9.9-99.9 °C Temperature measurement error: error within 0-50 °C is less than 1.2 °C, other range error is less than 2 °C Interface introduction: Power connector (blue screw terminal): The main power input interface supplies power to the control board and the fan. Fan interface (white VH3.96-4P socket): fan output interface, please refer to the picture for line sequence. Temperature probe interface: Connect probe parameter 10K B=3950. Alarm signal port (WORK): Outputs a high level during normal operation and outputs a low level when the fan is abnormal. Relay interface (RELAY): An expansion
