DC 12V 24V 48V 5A 2 3 4 Wire PWM Motor Fan Speed Controller

Four-wire PWM fan temperature control governor with control signal 10V, support common EBM four-wire fan.
Support conventional high-voltage EC fan four-wire control (10V PWM signal);support low temperature shutdown fan (PWM off or extended relay to turn off fan power ).
Wide voltage operation DC11-55V; Supports 2.5KHZ and 20KHZ frequency settings; Supports anti-timing fans.

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 NTC 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 interface that drives a 9V or 12V relay that can be used to control the fan power line. When the fan control is stopped, the relay is disconnected.
Material:plastic
colour:green
