Acxico 1Pcs DC 12V 24V 4A 2 Way Automatic PC CPU Fan Temperature Control Board PWM Speed Controller Module

Specifications:
Dynamic LED indicator light, intuitive understanding of the real work of the state governor.
The device is mostly used SMD package, stable performance, small size, saving space.
Product Dimensions: 56 * 35 * 20mm (Mounting M3)
Sensor cable length: 30cm
Applications:The outdoor enclosure, saving cabinet fan noise,Saving room fan noise,Other thermostat fan speed applications.

Instructions:
Follow the interface instructions to connect the power and fan cables.
Plug the temperature probe into the governor and fix the metal part of the probe to the heated area.
Turn the power on and the governor adjusts the fan speed based on the temperature detected by the temperature probe.
About the use of fixed mode and adjustable mode:
Fixed mode, the No. 10 switch to the F position, the governor temperature range is fixed to 30 low-speed start fan, 50-degree fan full-speed, then adjust No. 11 potentiometer useless.
Adjustable mode, start No. 10 to A position, when the governor temperature range by the No. 11 potentiometer settings. At the factory, The potentiometer No. 11 is in the middle position (the corresponding starting temperature is 20 degrees).No. 11 potentiometer clockwise slow rotation, the governor temperatureThe range will slowly increase and the temperature of the governor will change to the highest range (50 to 70 degrees) after one revolution.Counterclockwise rotation is the opposite, the temperature of the governor will change to 10 degrees after one revolution.

Number of fans connected = current of governor divided by current of single fan (for example, current of governor is 4a, if current of fan connected is 0.5A, number of fans connected = 4A / 0.5 = 8)

• This governor using PWM modulation technology to achieve temperature control, according to the ambient temperature of the governor to control the fan speed, the higher the temperature, the faster the speed, the ambient temperature is below the set start temperature when the governor to control the fan stops running.
• Whether it is a 2-wire, 3-wire or 4-wire fan, whether PWM or brushless fans, as long as the fan voltage is within 24V, current less than 4A, the governor apply! Also can drive a plurality of fans.
• The temperature sensor is connected with a cable in the form of mounting holes to facilitate detection of the temperature specified temperature point. Temperature probe is sealed with epoxy resin, waterproof and moisture-proof,the temperature probe maximum use temperature of 110 degrees, more than this temperature, the probe will be damaged.
• Fixed mode temperature and temperature of 30 degrees, the governor control fan start, 30 to 50 degrees fan speed linear increase, 50 degrees above the fan at full speed.
• Adjustable mode start-up temperature range: 10 to 50 degrees, full speed range of 30 to 70 degrees (start and full-speed temperature difference of 20 degrees).
