DC sovutish foniyining rangli simlari qanday ulangan?

DC sovutish ventilyatorlarida juda ko'p vilkalar mavjud va bu funktsiyalardan foydalanishdan oldin ularning funktsiyalari aniqlanishi va to'g'ri sozlanishi va ulanishi kerak.

    1. Connection of temperature measurement signal. The temperature signal generally uses the thermistor as the temperature sensor for temperature sampling. Taking the Tt Venus 12 fan as an example, the temperature change causes the resistance value of the thermistor to change, so the input signal has no polarity.

Termistorni protsessor va issiqlik batareyasi orasiga qo'ying, so'ngra fandagi sariq signal simining o'tkazgichini ajratib oling, DC sovutish foniyining sariq signal simini ulang va haroratni o'lchash signal simini ulash tugallandi. .

    2. The connection of the governor signal line. The manual governor is actually a variable resistor. When the resistance value is adjusted to the minimum (or short-circuited with a jumper), the speed of the fan is the lowest, and when the resistance is the largest (or the jumper is removed), the fan runs at full speed. There are two speed governors in the accessories of Tt Venus 12 fan, and one of them can be selected according to the situation.

It can be installed on the 3.5" floppy drive on the front panel of the mainframe, or in the slot on the back of the mainframe. Then connect the plug to the red wire socket of the DC cooling fan.
