2 Channel 4 Wire DC 12V 24V 48V PWM Motor Fan Speed Controller Digital Display Governor Temperature Control

2 Channel 4 Wire DC 12V 24V 48V PWM Motor Fan Speed Controller Digital Display Governor Temperature Control Description

1. DC 8-60V 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 damage the fan). 2. Dual temperature control, in turn show the temperature of the two channels (-9.9 to 70.1, error Less than 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). Operating voltage:DC8-60V (must be equal to the fan voltage, if you use 12V fan is powered 24V 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 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: 10K B = 3950 Temperature measurement:-9.9 to 99.9 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 Note:Due to different production batches, the appearance is different, which does not affect the use. Colour:Green Material:PCB+electronic components Size:Circuit size:65mmx65mmx15mm, positioning hole center distance 56mmx56mm diameter 3.2mm Package Contents: 1 * temperature control board 2 * cylindrical probe wire 1 * buzzer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
