Cooling Pwm Four-wire Fan, 12V, 24V, 48V

d c 12 24V 48V 2-Way 4-Wire Temperature Control Fan Speed PMW Fan Controller Display stop automatic Alarm

Controller Features:

1. d c8-60V wide operating voltage range (here refers to the control panel can work in this voltage range,
the actual operation of the controller power and fan is together, it must be in accordance with the fan power requirements, otherwise it will damage the fan).

2. Dual independent temperature control, in turn show the temperature of the two channels (-9.9 ° to 70.1 °, error <1 °)


3. Fan low speed and temperature control zone are set by key, flexible control, set a large range, set the program after the save.

4. Can set the switch stop alarm function (external AC buzzer long, the default off).

Performance parameters:

Operating voltage: d c8-60V (must be equal to the fan voltage, if you use 12V fan is powered 24V will burn the fan)

Operating Current: Control Panel Operating Current 35mA (12V) 22mA (24V)

Control capability: no fan current limit, but the board fan interface pin current should not be greater than 3A current,
use a larger current fan Please connect the fan power cord directly to the main power supply!

Control output range: 10% -100 (this is only the signal output range, the actual situation depends on fan performance)

Temperature probe specifications: NTC 10K B = 3950

3.25 after delivery for the updated version:

Temperature measurement: -9.9 ° to 99.9 degrees Celsius error 2 ° (1% probe 70 degrees Celsius) 3 ° (70 degrees Celsius above)

Temperature range: Acceleration temperature 5-94 °, full speed temperature 10-99 °

Speed measurement: 10-9990 rpm, more than this speed is always displayed 999, resolution 10 rpm,
the display unit is * 10 rpm (speed measurement in accordance with the common 2-pole signal fan design,
the vast majority of fans are 2-pole signal)

Stop alarm speed: less than 375rpm

Circuit size: 65mm * 65mm * 15mm, positioning hole center distance 56mm * 56mm diameter 3.2mm

Weight: motherboard + a pair of 1-meter-line cylindrical probe total of about 40g, a separate motherboard weight of about 23g.

Wiring instructions:

The blue screw terminal is connected to the main power supply
(the power supply voltage is equivalent to the fan voltage used and is in the range of 8-60V).
Please note that the positive and negative polarity should not be connected. "Channel 1" and "Channel 2" Fan,
line order is the power supply negative,
power positive, speed feedback, PWM control (see the wiring diagram below);
"Thermal 1" and "Thermal 2" connection NTC thermistor (parameter 10K B = 3950) ,
Respectively, with two channel fan temperature control temperature measurement;
"beep" jack connected AC buzzer, when the stop alarm,
the fan stops the buzzer will be long.

Wiring Note:

The allowable current for a single fan interface is 3A. If you need to control a fan with a higher current,
connect the fan power cord directly to the mains
(controller control capability is independent of the fan current and only the current capability of the power conductor).

Show description:
Control panel through the digital display of numerical value,
the right side of the four LED digital LED indicates the current value of the meaning of the line,
one or two led channel channel temperature and speed (x10rpm),
the second line of the two led on behalf of channel two Of the temperature and speed (x10rpm).
In the normal working state, the four values will be displayed in turn according to the order,
you can at any time by pressing the "+" "-" button to manually quickly switch the value of the manual switch will stay in this value for a long time
and then into the wheel status The You can shield out the display of channel 2 as needed.
