    Schematics Variable current 12v 60A to 0A

    Dazza, you could try an LM317 regulator (caution: the legs are not the same as the 78XX) and some resistors to get just below 8volts. The FDP7030 is worth a try.

    Charlie, You have to use a DC-DC step down circuit with isolation transformer.

    Need help with 2 ideas

    stuee, It is not necessary to use a shunt to measure the current. Just use the heavy wire as a shunt and an adjustable amplifier (op-amp) to interface the meter. Borrow a clamp am-meter and calibrate when the setup is ready. You should avoid putting in shunts in this circuit if not absolutely...

    Audioguru, You made me worried there, for a while I believed you have lost it. ;D Lower thermal resistance is good though. The circuit also need some change of resistor values and omitting the zener diode to work on 40Volts. And the LED is purple! ;D

    Pulse Width Modulation DC Motor Control

    Audioguru, The circuit generates a bad square wave, which is not very effective for PWM purposes. So there are circuits as simple but with better performance.

    Audioguru, Yes 30W each but with 0V out @ 5A, how often do you need 0V? You have to explain why a lower RDSon is better in this linear circuit, I think the RDSon is not very significant when running a mosfet
