Specifications:

Power supply: DC12V; the maximum range 11-14V; too low voltage displaying Lu; too high voltage displaying Hu; protection closed output

Output current: single channel maximum continuous output current 1.2A; double channels being both used at the same time current cannot exceed 2.0A; not suggesting using the fan with current being lower than 0.15A

Work efficiency: 90% (input 12V; output double way 8V 0.8A)

Reversely connected protection: short circuit reverse connection protection; power supply being connected reversely will burn out input copper foil
Overcurrent protection: no overcurrent protection; please note insulating installation; power up it after the wire is well connected to avoid output short circuit!! (only paid maintenance will be offered for overload and short circuit damage)

Thermal resistance parameters:NTC 10K B=3950

Measurement temperature error:1%-0.5?? after combining 1% probe, the maximum error 2%-1??br />
Board dimensions:92mm54mm (widthheight); location hole place:87mm47mm diameter 3.4mm

Itautomatically take turns to display channel 1 temperature, rotation speed, and channel 2 temperature, rotation speed under normal operation; quickly switch the display by pressing the “+” “-” button.

Parameter Setting:

Manual rotating speed setting (the minimum rotating speed under temperature control):
Press OK button to enter into rotating speed setting function; FAN1 2 indicator lights lighting up at the same time stands for current adjustment being fan 1s output size and by pressing the +&- button to adjust it with minimum 1 & maximum 100. After the setting, press OK button to enter into fan 2s output size setting; after the setting, press OK button again to exit and save the parameters.

Temperature control and stop-rotating alarm settings:

Under normal operating state, long-press OK button to enter into temperature control and stop-rotating alarm settings; indicator light on the right indicates corresponding setting channel; corresponding setting parameter display, meanings, and range ( stands for digit ):
L accelerating speed temperature setting,range 5-94?? lower than H at least 5??font color=’#ff0000’>,or adjust up H by linkage.
H full speed temperature setting; range 10-99?? higher than L at least 5?? or adjust down L by linkage.
F fan being shut off temperature; minimum 1; maximum limitation is lower than L 2?? when F00 is set, fan is not shut off.
bON / bOF: channel stop-rotating alarmon / off.

Adjust the setting value by pressing +&- button; press OK button to switch setting parameters; set the channel 1 according to the above sequence first, channel 2 second; press OK button at last to exit and save parameters.

Supplementary Instructions: when channel temperature reaches L after fan being shut off function is started, fan is started at minimum speed; it will accelerate with temperature increasing; when channel temperature is lower than F, fan is shut off. Corresponding channel stop-rotating alarm will automatically block shut-off statuss rotating speed check.

Shutting off channel 2 display:

One channel is needed for some application and now channel 2 can be shut off; the setting method: keep pressing OK button to make it be powered up with controller not being powered up; controller entering into channel 2displays setting status; modify the setting by pressing +&- button; 2ON / 2OF stands for channel 2 display / no display; after the setting, press OK button to save it, exit and enter into operating status.

Note: after channel 2 display being shut off, it will not display channel 2s rotating speed and temperature only on LED display; it will not affect channel 2s function.

Package included:

1 x Fan temperature controller
2 x Temperature probe
1 x Buzzer
