激光刻章机专用电源、深圳刻章机免费维修、技术教学

本电源采用零电流半桥软开关电路，使电源具有效率高，响应速度快的特点，很容易配合各种厂家的激光管。
　　端口 控制简单，很容易安装机器，配合板卡信号，同时加有异常保护开关，检测外部是否通水、通风等。
　　激光功率调节既可以输入0到5v的模拟信号，也可以输入pwm信号用以控制激光功率的大小。
　　电源具有开路保护功能：在保护接地良好的情况下，电源可以短时间工作于开路状态，这样可以避免因激光管爆裂造成激光电源的损坏。
　　同时输出24v,和5v,方便机器的安装与调试。
出厂老化试验:
　　每台电源都会经过满载状态下高温60度12小时老化试验,7秒钟开停电源试验500次
