    江西景光电子有限公司近年开发生产的适用于德国罗芬激光器作激励功率源用的*K12-4电子管现已大量供应欧美和国内市场。该电子管用在罗芬公司DC010、DC015激光器上,激励功率小于1.5千瓦,在国内与多家激光机生产厂家整机配套。如上海团结普瑞玛激光切割机SLCE-12*18H(非金属切割,如木材木板,PVC板材)激光功率源就选择这款产品。国内终端用户在更新维修时也多因性价比和国内售后服务便利的优势选择该国产管作为替代产品。The *K 12-4 is a high-power, high-μ triode designed specifically for industrial applications.This tube uses a coaxial design and metal-ceramic technology. It may be operated in CW or pulse modes. For operation in pulse mode, the parameters depends on each equipment characteristics,contact us for specific information.This product is designed, developed and manufactured at an ISO 9001 registered production site.
