一、概述:我厂生产的500MAX 线机电子控时器,专供摄影曝光时限的控制。为了保证低秒数(如10MS、20MS…)摄影的时限准确;以及曝光开始与结束瞬间离压器次级产生操作过电压(一般不超过额定电压的2～3倍)。因此在线路上采用“电压零相位”接通及切断高压变 First, an overview: I plant production of 500MAX wire machine electronic timer, designed for photographic exposure time control. In order to ensure low seconds (such as 10MS, 20MS ...) accurate timing of the filming; and start and end of the exposure instantaneous secondary pressure generator over-voltage operation (usually not exceed the rated voltage of 2 to 3 times). Therefore, the use of “zero-voltage phase” connected and cut off high-pressure change
