SIREGRAPH CF是西门子公司生产的800mA简易胃肠X线机,整机性能稳定,图像质量高。主电源要求稳压380VAC,为安全及使用方便考虑,自行设计了低电压控制主电源通断系统。 电路原理如下图所示。 配电房输出的稳压380VAC送至K,K的闭合使得T的初级得电220VAC,则次级输出18VAC经Q
SIREGRAPH CF is an 800mA simple gastrointestinal X-ray machine manufactured by Siemens. The machine features stable performance and high image quality. The main power supply requires a voltage regulator of 380 VAC. For safety and ease of use, it has designed a low-voltage control main power system. The circuit principle is shown in the figure below. The 380VAC output of the power distribution room is sent to K, and the closing of K makes the primary power of T get 220VAC, then the secondary output is 18VAC via Q.
