2-3 Wire DC 5V 12V PWM Fan Speed Controller Governor NTC 50K Temperature Probe Sensor 40cm Temperature Controller

Description: 1. 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 power. 2. Please note that the power supply voltage must match the fan voltage 3. 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 Color: As shown Material: PC+Metal Parameters: Probe: 40cm Working 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: 10-30mA Temperature probe model: 50K B=3950 Circuit 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 7mm Factory 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: 1. The fan current cannot exceed 0.9A 2. The controller does not participate in speed measurement 3. Do not connect the reverse polarity Board operating voltage range: DC 4.5-13.5V Abnormal status indication: No output 1 light flashes quickly: power supply voltage is too low No output 3 light flashes quickly: power supply voltage is too high Package Contents: 1 x Temperature Control Speed Controller Governor Regulator
