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

Note:

• The fan current cannot exceed 0.9A
• The controller does not participate in speed measurement
• Do not connect the reverse polarity!!
• Board operating voltage range: DC 4.5-13.5V

Abnormal status indication:

• No output “1” light flashes quickly: supply voltage is too low
• No output “3” light flashes quickly: supply voltage is too high

Package Contents:

•  1 x Temperature Control Speed Controller Governor Regulator
