DC 12V 5A NPC PWM PC CPU Fan Temperature Control Speed Controller Alarm E97

Features:
Support all within 12V 5A 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 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).
 
Specifications:
Working voltage: DC12V
Circuit load capacity: maximum current per output 5A, 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
High Accuracy NTC Thermistor Temperature Sensor Module 3950K B-value, 10kohm R25, 0.1% Sampling Resistor Accuracy for Arduino
 
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):
