一、用途 JBK5系列控制变压器是我公司引进国外最新变压器系列，在国内JBK3系列控制变压器基 础上，经过多年来进一步吸收国外同类产品，并优选国外先进方法的接线端子结构、将端 子与骨架合并在一起，防护等级提高到IP2LX，防止偶然触及电路。采用IT冷压接线端子，接线方式可以使接线密集程度提高。变压器硅钢片与硅钢片之间联结、硅钢片与底板之间联结均采用氩弧焊工艺，形成一个整体，简捷明了。尤其底板一次成型，安装与外形尺寸较JBK3系列更为准确，而且采用优质防蚀合金材料，大大提高了接地性能的可靠性，全面提高了产品的质量，该产品符合VDE0550、IEC204-1、IEC439、GB5226等有关国际、国家标准，并荣获欧共体“CE”认证，可与国外产品互换使用。JBK5系列控制变压器适用于交流50-60HZ，输入电压不超过220V，输入额定电压不超过500V，作为各行业的机械设备，一般电器的控制电源和工作、信号灯的电源之用。l
Use
The JBK5 series control transformer introduces the overseas newesttransformer series in our company, in the domestic JBK3 series controltransformer foundation, further has absorbed the overseas similar productafter for many years, and selects the optimal overseas advanced methodterminal structure, the terminal and the framework merges in together, theprotection grade enhances IP2LX, prevented accidentally touches the electriccircuit. Uses the IT cold-press terminal, the wiring way may cause the wiringcrowded degree enhancement.Between the silicon steel plate, between the silicon steel plate and thenether plate joins uses the argon welding, forms a whole, simple and direct perspicuity. Especially the nether plate formation, the installment and theexternal dimensions compare the JBK3 series to be more accurate, moreover uses the high quality corrosion prevention alloy material, enhanced theearth performance reliability greatly, improved the product qualitycomprehensively, this product conforms to VDE0550, IEC204-1, IEC439,GB5226 related and so on international, the national standards, and has the honor to receive the European Economic Community “CE” theauthentication, but and overseas product exchange use. The JBK5 seriescontrol transformer is suitable in 50-60HZ, the input voltage 220V, theinput rated voltage 500V, takes power source ofcommon electric appliance control and work, the signal lamp in various professions the mechanical device. 二：型号及其含义（Outline and installation size
