della corrente massima di 62,5 Ampere con una potenza totale di 750 W, ma modificando l\u2019uscita della tensione da 12 a 13,8Vdc ne consegue che, per la nota legge di Ohm, la corrente del presente alimentatore sar\u00e0 ridotta a 54 Ampere come meglio specificato di seguito:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>La corrente alla tensione di 13,8 V sar\u00e0: I = 750 W\/13,8 V = 54,35 A<\/li>\n\n\n\n<li>La potenza sar\u00e0: 54,35 A x 13,8 V = 727,20 W<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"620\"

transitare allo shunt per una corretta lettura della corrente sullo strumento, si raccomanda una adeguata sezione del cavo di potenza da utilizzare vista la corrente massima di 60 amper che pu\u00f2 transitare, personalmente ho utilizzato dei conduttori extra flessibili della sezione di 6mm\u00b2 (uno Rosso e l&#8217;altro Nero).<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images
