我们在使用和维修614型交流稳压电源时,发现开机瞬间的冲击电压较高,个别稳压电源损坏后,出现输出电压增高的现象,甚至超过280V,对用它供电的仪器或设备,造成一种潜在的威胁,对于很多自身没有过压保护的仪器和设备威胁更大,甚至造成损坏。针对以上情况,我们为614系列交流稳压电源设计安装了延时供电和高失调保护装置,现介绍给大家,供参考。
When we used and maintained Type 614 AC regulated power supply, we found that the instantaneous impulse voltage at power-on was high. After the individual regulated power supply was damaged, the output voltage increased even more than 280V, which caused the power supply of instruments or equipment A potential threat poses a greater threat and damage to many instruments and devices that do not themselves have over-voltage protection. In view of the above situation, we design and install the delay power supply and the high offset protection device for the 614 series AC regulated power supply, and are introduced to you for reference.
