SF-KTWS-IV全数字直流调速装置：  KTWS型微机控制直流调速柜是用英国欧陆590、591控制器作为中心部件组成，采用框架结构、标准机柜。它充分发挥了590、591控制器所特有的功能，具有国际范围的应用品质，使调整更为简单方便，使运行更为稳定可靠。·SF-KTWS全数字直流调速设备特点（英国欧陆）：·THE CHARACTERISTIC OF SF-KTWS TOTAL DIGITAL DIRECT CURRENT TIMING DEVICE(ENGLISH INEUROPEAN CONTINENT欧陆)：1、全数字直流调速设备，采用标准机柜，框架结构,元件板镀锌。1、Total digital direct current timing device adopt the standard machine tank, frame structure, organ board galvanization.2、核心部件采用英国欧陆原装控制器。2、The center parts adopt original controller from Englishin European continent.欧陆3、励磁采用隔离供电方式，即单独配置励磁变压器，工作更加稳定，同时保护了欧陆控制器。3、Excitation adopt the isolation way of the power supply, it means deploy the excitation transformer solely. This can make the work more stable while protect the controller.4、设有内控、外控。4、It set the inner control and outer control.5、控制器供电、控制电路均与电源隔离。5、The power supply of the controller and control circuit both isolate from the power supply.6、正、反转转换可靠（设有延时继电器）6、The switch of the positive turn and reversal is credible. (setting the relay for delaying time)7、具有过电流、速度反馈故障、励磁故障、电源故障、 超速 、电动机过热 、堵转 、过电压等保护功能。7、It has the protect functions in case of the failure to cross the electricity, speed feedback , excitation and power, over-speed, overheat of the electromotor, the stop of the transfer ,over voltage and so on. 8、操作简单方便，只需把电机参数输入控制器存储即可。8、The operation is simple and convenient, only need to input the electrical engine‘s parameter into the controller storage.9、外围配置空开、进线电抗器、励磁变压器、指示仪表，操作控制及反转控制、多台联动同步控制等功能。9、It also has the functions of the outside opening device(外围配置空开),entering line reactor , excitation transformer, direct instrument, operation controller ,reversal controller and synchronous controlling of many sets linkage.
