IC693CHS391CA
●内置PID控制功能●完善的20种保护功能--功率单元自身多达11种故障保护功能;电气部分对输出电压、输出电流、输入电压、输入电流都有的检测,对变频器电源及电机都有过压、过流、欠压、温度等多达20多种保护功能;重要保护定值可以根据现场不同的工况进行参数设定,内置雷击过流保护装置,提高了设备的保护功能和系统的保护功能;●宽范围抗电压波动能力--宽电压适应性强,允许网侧电压在10%~-15%之间波动。同时具有AVR功能,能够根据母线电压的波动自动调整输出电压。网侧电压在短时间小于85%~65%额定值或大于110%~120%额定值,高压变频调速系统不停机,保证电机持续运行;
●超长瞬时掉电不停机,有效避免电网不稳定带来的停机问题--我司高压变频器采用的瞬停处理方式,可以做到适应电网晃电1S以上,不管是风机,还是水泵,都可以做到该效果。如果风机类负载,多可以电网晃电5S都没有问题;
