SFN3990正弦滤波器(SPWM)

简要描述:

详细介绍

SPWM滤波器手册

一.由于变频器的输出含有高谐波,增加了动力电缆及电机的损耗。
如果电机需要长线传输时(电机线缆超过50米),由于行波反射引起电机端电压叠加,使电机绝缘破坏,甚至使电缆爆裂。

能同时解决以上问题的有效方法使在变频器输出侧加装滤波器,将PWM调制波成近似正弦的电压波形,并使电机和变频器的线缆延长

二.  技术规格

1.工作电压AC660/690V 可选择
2.额定电流:52000A
3.基波频率50/60Hz
4.载波频率:2KHz20KHz 
5.压测试:3000V AC 3
6.防护等级:IP00
7.绝缘等级:/F 155
8.温度范围:-25 to +85(风机)

9.过载:1.35倍电流60s(基波电流)

10.周围无有害气体,无易燃易爆物品 周围环境应有良好的通风条件,如装在柜内应加装通风设 

订货须知.电压.电流.载波频率.变频器是重载或轻载。
