408UL文档输出设备电源工作原理

Work principle of power in 408UL file output device

408UL遥测地震仪记录系统稳定可靠,应用广泛。然而,该系统没有附带电路原理图,损坏后维修难度较大。我们在维修408UL文档输出设备电源的过程中,根据实物绘制出该电源的电路原理图。本文阐述该设备电源电路的工作原理。

The 408UL telemetry recording system is characteristics of stability, reliability and wide use. But because of lack of additional circuit diagrams, it is difficult to repair if the power is damaged. During the maintenance of power in 408UL file output device, we have drawn the circuit diagrams of power according to material object. The paper detailed expounded the work principle of the power circuit of the device.
