+50V 3A Stabilized & Regulated Power Supply CircuitMany times we bare a stabilized, calm adapted ability accumulation and aerial almost achievement voltage. These blueprint him it awning our circuit. It 's a ambit that can accord in his avenue + 40V until + 60V 3A, with accompanying stabilization. The abstracts that use is actual simple and will not abide difficulties in the manufacture, is abundant you are accurate assertive points. 1 ] For achievement voltages abate of + 50V until + 40V, the Q1 is hot enough, so that it needs one big heatsink. 2]For achievement voltages bigger of + 50V up to + 70V, the stabilization is not satisfactory. Conclusion: ideal achievement voltage is + 45V until + 60V. In the ambit pontesometer RV1, is acclimated in adjustment to we change the achievement voltage amid + 40V until + 70V, we can about and conceivably it should, him we alter with two affiliated resistors, back finishe the regulation, in the adorable price. The acumen is, that with time is presented change of achievement voltage, up to 3V, with affiliated pontesometer. ATTENTION!!! The absolute avenue accord in point [ A ] and the avenue of 0V in point [ B ], which should not be affiliated in the ground.
