7812 and 2N3055 12v-15 Volt 20 Amp Power Supply

Heavy bulky quite strong and a shake 🙂 a power supply circuit is adjustable from 12 … 15 volt regulator integrated 12volt classic L7812 was carried out by increasing the flow of

Integrated control of the L7812 (12v positive regulator) integrated output power of 1 Ampere output used to strengthen the BD708 MJ2955

Transformer Troidal you can use a maximum of 25 Amps can give (known price is higher) will be lighter and more efficient, it can be difficult to find the right size cooler do you use a smaller cooler fan cooler to add

    Bitmap (BMP) Protel PCB converter

    Protel printed circuit converter program that you can use in a drawing program. Language is English, but very easy to use and does not require installation
    Bmp image formats PCB in Protel PCB Files Format to turn the program into

    BITMAP to PROTEL PCB CONVERTER

    This program was designed to allow importing of bitmap images onto a Protel PCB. The ouput of this program is a generic Protel PCB file. Simply open this PCB design in the PCB editor, select and copy this area. Then paste the image onto your circuit board design.

    Heavy sperrig ziemlich stark und ein Shake 🙂 ein Stromversorgungskreis ist einstellbar von 12 … 15 Volt Regler integriert 12volt klassischen L7812 wurde durch die Erhöhung der Strömung durchgeführt

    Integrierte Steuerung des L7812 (12V positiver Regler) integrierte Ausgangsleistung von 1 Ampere Ausgang zur Verstärkung des BD708 MJ2955

    Transformer Troidal können Sie maximal 25 Ampere geben können (bekannter Preis ist höher) wird leichter und effizienter sein, es kann schwierig sein, die richtige Größe Kühler zu finden, verwenden Sie einen kleineren Kühler Lüfter Kühler zu addieren

    Zdravím. Akú úpravu by chcelo zapojenie, aby šlo regulovať od 7 volt do 15 volt?

      Hi,

      Use LM317 instead of 7812. You can try the following circuit. (I didn’t apply it)
