12V CPU Fan Temperature Control PWM Speed Controller Module Alarm Buzzer Sensor Drop Shipping

Description:

Support all within 12V 4A fans, synchronous rectifier output, high efficiency! Even if a large current work does not require additional heat sink! A plurality of fans can be used in parallel (total current does not exceed 5A), supports automatic temperature control and manumotive speed control, temperature control speed with four temperature zones for setting up, easy to apply in a variety of applications! It can be opened with a three-wire fan monitoring function (stall warning).

1.channel: temperature control

2.channel: manual operation

3.High-Temp Alarm

4.Automatic temperature control regulator speed

Specifications

Working voltage:DC12V 

Circuit load capacity: maximum current per output 4A, the bus currents up 9A

Output Range: The first channel 20% -100, or 40% -100 (TFL = ON)

The second channel and the third channel 10% -100

Note: Above range only for PWM range, the actual control effect will vary depending on the fan.)

Temperature probe parameters: 50K B = 3950

Thermostat temperature zone error: error depending on the temperature probe, generally 3-5%

Stall alarm minimum speed: 700-800 rpm

Function setting switch Description:

TFL (No. 1): The lowest temperature channel PWM setting, when ON state FAN1 PWM minimum is 40%, when OFF the minimum PWM of FAN1 is 20%.

TP1 TP2 (No. 2,3): Temperature channel control temperature zones are interpreted as follows (need to used with the temperature probe):

TP1 TP2 Accelerating temperature Full speed temperature

OFF OFF 35°                 45°

ON OFF   40°                 55°

OFF ON   50°                 70°

ON ON     60°                 90°
