12V PWM 2-3 Wire Fan Temperature Control Speed Controller

This controller supports 2-3 wire fan temperature control and speed regulation with DC 5V-12V current not exceeding 0.9A, through smooth voltage reduction control, and supports low temperature shutdown of the fan. Please note that the supply voltage must match the fan voltage! Please pay attention to the positive and negative polarity of the wiring! If the connection is reversed, the circuit board “FUSE bit” may be burnt.Features:Material: PC MetalParameters:Probe: 40cmWorking voltage: DC 5-12V (board working range DC 4.6-13.5V, over-range protection)Control fan current: 0.1-0.9A (lower than 0.1A fan control effect is poor)Circuit self-consumption: 10-30mATemperature probe model: 50K B=3950Circuit operating temperature: -10℃ to 60℃Probe temperature resistance: small blackhead 120℃, ring probe 110℃Board size: 54mm x 13mm x 8mm (without interface), the fan interface extends 7mmFactory default settings: basic speed control output Po=35%, acceleration temperature Tu=30°C, temperature control interval Td=5°C (35°C full speed), and the fan does not shut down when the temperature is low.Note:The fan current cannot exceed 0.9AThe controller does not participate in speed measurementDo not connect the reverse polarity!!Board operating voltage range: DC 4.5-13.5VAbnormal status indication:No output “1” light flashes quickly: supply voltage is too lowNo output “3” light flashes quickly: supply voltage is too highPackage Contents: 1 x Temperature Control Speed Controller Governor Regulator
