产品特点 Features

1.铝合金外壳或钢板焊接,表面喷塑;
2.内装富士、西门子或施耐德等公司生产的变频器、断路器、信号灯等元件
3.它主要通过改变其输出频率来调节普通三相异步电动机的转速, 以达到生产工艺要求或实现节电的目的, 节电率可达30%~60%,也可作为电动机软起动控制器,也可通过传感器、变送器等控制电路组成闭环调速系统,安装操作简单,功率因数恒定,同时具备故障显示等各种功能;
4.具有过电流、短路、过电压、欠压、断相等多种保护,可数字显示频率、转速以及负载率或电流等,可手动调节频率,可
设定转速按时间变化的工艺曲线,也可由DCS系统给出信号来控制其频率;
5.钢管或电缆布线。
1.Enclosure is cast with aluminium alloy, or welded by steel plate, surface is sprayed with plastic, fine outline;
2.Built-in frequency converter, circuit breakers, signal lamps etc of FWI ro sehneider;
3.It can adjust the rotate apeed of three phase asynchronism motor by changing output frequency, percent of energy servingcan reach 30%-60%, it also can be used as motor soft start controller, the transducer, transmission are composed a sealingtiming system, simple digital operation, power factor is invariable and with many functions, like error displaying;
4.With protection of over current, short circuit, over voltage, short voltage and loss phase, and adjust the frequency, bymanual the craftwork curve can be set according to rotating speed changing with time transfering, the DCS system also cansend out signal to control the frequecy;
5.Wiring with steel tube or cable.
