2-3 4 Wires DC 5V/12V PWM Fan Temperature Speed Controller Governor Switch Temperature Control Module For PC Fan VHM-802 10/40CM

Type A Description:

The controller only controls the speed of the four line standard specification Intel PWM fan, do not turn off the fan. With full digital control, accurate temperature setting and precise control. It integrates manual speed regulation and automatic temperature control and speed regulation function. Manual speed control from 10, each 5% is a gear. Automatic temperature control speed from 30 degrees Celsius, there are 49 kinds of temperature zone combination. It supports three line to four line control, setting parameters automatically save.

3. Components:

1>. Input line: red black power line is only welding 12V positive and negative power cord, as a

general use. The three wire connector is equipped with a 2510-3P plug, which is used to

measure the speed of some main board three wire fan ports. Large 4P interface facilitates

power acquisition from chassis.

2>. temperature probe: small black line's head is short, low heat capacity. It is suitable for

testing narrow space and air temperature, and the response is relatively fast. The ring probe

is enclosed inside a ring metal head with a diameter of 4.2mm. It is suitable for mounting on

the radiator or other heating object surface with screws.

4. Manual automatic integration control:

3 parameters are adjusted: start speed po, start temperature increase Tu revolutions and Delta TD temperature when the revolutions reach the maximum. Po is set after switching on. Double click down, single up. 1 + 2 burns reach a minimum, 2 + 3 maximum revolutions. To configure Tu keep 3 seconds, start flashing slowly. Also click and put the value on the table. Keep another 3 seconds, start flashing fast, customize TD.

1>. Manual control without temperature probe. Click / double-click (double-click speed not too

fast) button up / down gear. Each shift continues after 20 seconds, and the gear is

automatically stored. The No. 2 indicator flashes rapidly in 20 seconds (when the temperature

control is invalid). When the flash is stopped, it indicates that the file has been stored. The 3 /

1 indicator light is always on when you can not continue to increase / not continue to reduce

the position.

2>. When the temperature probe is installed, the manual speed is used as the initial low

speed (bottom line speed). When the temperature exceeds the accelerating temperature, the

fan speed accelerates smoothly with the increase of temperature.

When the temperature reaches and exceeds the sum of the acceleration temperature and the

acceleration width (full speed temperature), the fan runs at full speed.

Set the acceleration temperature and acceleration width parameters as shown in the

schematic diagram below. The number 123 represents the indicator light on the board (red)

and the (white) state is displayed in binary order:

5. Example instruction:

Bottom line 20%, acceleration temperature 35, acceleration width 15.

When the probe temperature is lower than 35 degrees centigrade, the output signal is always

20%. When the probe temperature is higher than 35 degrees, the controller can increase the

output signal smoothly according to the temperature rise, and the fan accelerates. When the

probe temperature reaches or exceeds 50 (35+15), the controller outputs the full speed

signal and the fan runs at full speed.

According to the specific performance of the fan, the actual speed of the fan will be somewhat different.

6. Setting method:

P.S. The controller has supported the control of the reverse timing fan.

First, power off and remove the fan. Press the set button to electrify the controller. Keep the

settings button always hold (about 3 seconds) until the three lights turn into double flash state

and then release the
