DAM中波广播数字调幅发射机的控制板用来控制发射机的开关机、输出功率的升降,在发射机发生故障或出现过载现象时输出保护指令;显示板对故障及过载现象进行检测,输出相应状态信号到控制板,并在面板显示发射机的工作状态。控制板上稳压电源出现故障会造成部分控制功能散失,本文践行故障实例,对控制板稳压电源在整机中的效用进行研究,提出整改建议,供大家参考。
DAM medium wave radio digital amplitude modulation transmitter control panel used to control the transmitter on and off, the output power of the lift, the transmitter fails or overload protection output when the command; display panel fault and overload phenomena are detected, the output The corresponding status signal to the control panel, and the panel shows the working status of the transmitter. Control board power supply failure will cause some of the loss of control functions, this article practice examples of failure, the control board power supply in the machine to study the effectiveness of the proposed rectification, for your reference.
