2-3 Wire DC 5V 12V PWM Fan Speed Controller Governor 50K

2-3 Wire DC 5V 12V PWM Fan Speed Controller Governor 50K Description

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=30C, temperature control interval Td=5C (35C 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
