Performance parameters:


2. Operating Current: control panel operating current 35mA (l2V) 22mA (24V)

4. Control Output Range: 10% —l00%(this is the signal output range; the actual situation depends on fan performance) 

6. Temperature Measurement: -9.9℃ to 99.9 ℃, error <2℃ (1% probe with 70℃) 3℃>70℃

8. Speed Measurement: 10-9990 rpm, exceeding the speed displaying 999; resolution 10 rpm, display unit *10 rpm (speed measurement is based on common 2-pole signal fan design; most of the fans are 2-pole signal)

10. Circuit dimensions: 65mm*65mm*15mm, location hole center distance 56mm*56mm, diameter 3.2mm

Wiring instructions:

Connect blue screw connector to the main power supply (power supply voltage is equal to using fan voltage within 8-60v range); please do not connect reversely; connect “channel 1” and “channel 2” two 4P socket to the fan and power supply negative, positive, speed feedback, and PWM Control (For details, see wire connecting diagram below); connecting “thermal 1” and ”thermal 2” to NTC thermistor (parameter 10K B =3950) uses respectively two-channel fan temperature control measuring temperature; connect “beeping” connector to AC buzzer and when stop-rotating alarm is started, fan stop-rotating buzzer keeps beeping.

Wiring Note:

Single fan connector let-through current is 3A; if you need to control the higher current fan, please connect the fan power supply cable directly to the main power supply (controller controlling ability has nothing to do with fan current and please consider the power supply cable’s current let-through ability).

Display Description:

Control board display value by LED display; 4 indicating LED display on the right of the LED display meanings: line 1_two LEDs respectively stands for channel 1’s temperature and speed (x10rpm) and line 2_two LEDs respectively stands for channel 2’s temperature and speed (x10rpm). Under normal operating conditions, the four digit values will take turns to display; quickly switch digit values manually at any time by pressing the "+" "-" button; after the manual switch, it will stay under this digit value for a long time to return to taking-turns displaying. You can block 0ut the channel 2’s display according to your need.

Setting Description:

1. Basic speed settings: basic speed setting for adjusting fan speed before temperature control is started, which is the fan speed when it is lower than the accelerating speed temperature. Setting method: press the "OK" button in any operating state and at the moment, channel 1_two LEDs light up at the same time horizontally with LED display showing current setting value (10-100); set the size by pressing the “+”&“-”
