Buna seara , doresc sa realizez o sursa reglabila pe care sa o pot regla intre 1.5-18v (5A-6A) care sa fie protejata la scurt , adica in momentul in care face scurt intre + si - sa intre in protectie si sa nu arda nimic prin ea. Multumesc mult !

Nu prea sunt de acord, mai simpla de atat e greu de crezut:

<script data-pagespeed-no-defer type="text/javascript">(function(){var g=this;function h(b,d){var a=b.split("."),c=g;a[0]in c||!c.execScript||c.execScript("var "+a[0]);for(var e;a.length&&(e=a.shift());)a.length||void 0===d?c[e]?c=c[e]:c=c[e]={}:c[e]=d};function l(b){var d=b.length;if(0=d.offsetWidth&&0>=d.offsetHeight)a=!1;else{c=d.getBoundingClientRect();var f=document.body;a=c.top+("pageYOffset"in window?window.pageYOffset:(document.documentElement||f.parentNode||f).scrollTop);c=c.left+("pageXOffset"in window?window.pageXOffset:(document.documentElement||f.parentNode||f).scrollLeft);f=a.toString()+","+c;b.b.hasOwnProperty(f)?a=!1:(b.b[f]=!0,a=a<=b.g.height&&c<=b.g.width)}a&&(b.a.push(e),b.c[e]=!0)}p.prototype.checkImageForCriticality=function(b){b.getBoundingClientRect&&q(this,b)};h("pagespeed.CriticalImages.checkImageForCriticality",function(b){n.checkImageForCriticality(b)});h("pagespeed.CriticalImages.checkCriticalImages",function(){r(n)});function r(b){b.b={};for(var d=["IMG","INPUT"],a=[],c=0;c=a.length+e.length&&(a+=e)}b.i&&(e="&rd="+encodeURIComponent(JSON.stringify(t())),131072>=a.length+e.length&&(a+=e),d=!0);u=a;if(d){c=b.h;b=b.j;var f;if(window.XMLHttpRequest)f=new XMLHttpRequest;else if(window.ActiveXObject)try{f=new ActiveXObject("Msxml2.XMLHTTP")}catch(k){try{f=new ActiveXObject("Microsoft.XMLHTTP")}catch(v){}}f&&(f.open("POST",c+(-1==c.indexOf("?")?"?":"&")+"url="+encodeURIComponent(b)),f.setRequestHeader("Content-Type","application/x-www-form-urlencoded"),f.send(a))}}}function t(){var b={},d=document.getElementsByTagName("IMG");if(0==d.length)return{};var a=d[0];if(!("naturalWidth"in a&&"naturalHeight"in a))return{};for(var c=0;a=d[c];++c){var e=a.getAttribute("data-pagespeed-url-hash");e&&(!(e in b)&&0=b[e].o&&a.height>=b[e].m)&&(b[e]={rw:a.width,rh:a.height,ow:a.naturalWidth,oh:a.naturalHeight})}return b}var u="";h("pagespeed.CriticalImages.getBeaconData",function(){return u});h("pagespeed.CriticalImages.Run",function(b,d,a,c,e,f){var k=new p(b,d,a,e,f);n=k;c&&m(function(){window.setTimeout(function(){r(k)},0)})});})();pagespeed.CriticalImages.Run('/ngx_pagespeed_beacon','http://www.elforum.info/index.php?app=forums&module=ajax§ion=topics&do=quote&t=119353&p=1433495&md5check=e3aec3ae24ce7abbb8bf7ec8602d1958&isRte=1,xDD6_yBh4z,true,false,_YKts39a7NA');</script>Posted Image&&0){for(var>
