  6. Symmetrical supply in cars

    There is a problem if you want to use a car battery to power a circuit which requires a symmetrical supply voltage. Having abandoned the idea of mounting a second battery in your car for that purpose, take a serious look at the circuit discussed here. It converts the car battery voltage into symmetrical ?12 V or even ?15 V rails. Since the converter is able to supply a continuous output current of about 0.5 A, and a peak current of up to 1 A, it is eminently suited to powering control amplifiers and small power amplifiers.

  9. Alimentator 0-30V 10A

    Pentru laboratorul vostru, am atasat o sursă de alimentare cu LM723, capabil sa livreze o tensiune de ieşire ?ntre 0 şi 30 V cu un curent maxim de 10 Amperi. Sursa este protejata ?mpotriva scurtcircuitelor şi permite ajustarea completă a pragului de protectie de la 50 mA la 10 A. Tensiunea continua este filtrata de condensatoare cu o capacitate de circa 20.000 uF, iar pentru semnalizarea prezentei puterii de RF pe linia de alimentare sursa a fost prevazuta cu un indicator. Cu ajutorul potentiometrului P1 se regleaza tensiunea de iesire.
    OBSERVATIE!!!! Dioda D3 din imaginea cu amplasarea componentelor electronice pe cablaj este montata pe dos.
