    bro ini JMC DATECH yg sudah saya modif dengan mem-paralel-kan POT LINIER 50K ohm ke sensor dan tambahan switch buat off-kan POT.








    ini rangkaiannya

    gw gak punya potensio 2K, jadi gw gabung aja 2 biji pot 1K dibikin seri.
    kalo resistor 4K7, gw dapet dr try&error aja.


    @chAotic blAck
    kabel putih di jmc/datech 2A, apaan sih? buat ke sensors bukan?

    btw resistor 4K7 tuh resistor berpa kOhms???

    kabel putih d DATECH 2A tuh kalo d situsnya dsbutin kabel sensor/tach tapi pernah coba colokin k mobo gk detect sama sekali....ato butuh tambahan rangkaian khusus lagi biar bisa enable yah???

    1K = 1000 OHM
    4K7 = 4700 OHM

    @badjoe
    udah di jelasin sama bro zungkono.
    4K7 = 4.7K ohm
    1K = 1K ohm

    kalo maslah potensio, mending coba2 aja bro.
    harga potensio kan murah, paling Rp1500-2500/biji (harga POT 100K s/d 1K biasanya sama aja kok)
    smooth apa nggak itukan tergantung org yg makenya

    makin banyak coba2, makin banyak ilmu dr pengalaman yg didapetin.


    Jadilah org pintar. Seperti Padi, Yg Semakin Berisi, Semakin Merunduk.

    Re: [ASK] Fan controller murmer



    brhbung nubie soal elektronika n perlengkapan "tempur" jg gk ada mkanya sourcing sebanyak2 dulu Oms....

    mksd ane smoothnya tuh se-linear apakah perubahan putaran kipas dengan putaran POT-ny Oms???

    kemaren cobain pake POT 10K sensi banged putarannya....
    mulai d +/- setenga puteran baru mulai naek..tapi geser dikit aja putaran kipas langsung kuenchuengggg..... wakss...

    semakin besar R maka lebih baik toh ? itu juga tergantung kualitas POTnya, kan macam2

    sama bro, gw juga nubi banget.
    makanya gw beli potensio yg murah aja & macem2, dr 100K, 50K, 10K, 5K, 2K, 1K.
    sama sisa sedikit resistor dr bikin PWM controler.

    kalo semakin tinggi nilai POTnya, so makin sensi juga.
    kalo nilai POTnya terlalu rendah, bikin FAN nya jadi gak bisa dapetin full RPM ato ngedapetin RPM terendah
    jadi coba deh pake POT yg lebih rendah
