我是采用494做震动再加两个TIP42放大推动20个3DD155
能使2个200W 1个100W的灯泡发亮,两端电压是223V
输出功率还算不小了吧,想测空载,用9028的数字表接上10A档.机子启都不启动了(表线有温度)
请问大虾们是啥问题呢?????????????500) {this.resized=true; this.width=500; this.alt='这是一张缩略图,点击可放大。\n按住CTRL,滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/60/2297001197437878.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">
