Product Details of3 Phase 4 Wire High Performance EMI Filter

Product Description 

This kind of 3 Phase 4 Wire High Performance EMI Filter is placed at the output end of the inverter, which can effectively extend the rise time of the PWM pulse at the output of the inverter and reduce the rate of change of the voltage, it has a good effect on the insulation of the protection motor. If the running cable between the inverter and the motor is too long, it will cause a devastating effect on the motor. The length of the cable depends on the number of switching of the power semiconductor used in the inverter and the size of the motor. If the cable is as short as 2.5 meters, the peak voltage that the motor is subjected to exceeds the rating of the motor insulation system. However, if the cable is too long, the problem is even greater, in which case the 3 Phase 4 Wire High Performance EMI Filter is required to protect the motor from the devastating effects of the peak voltage. Besides, it is widely applied in medical equipment, power systems, machine tools, etc. 


Applications

Available for digital systems, telecom systems. medical equipments and industrial installationsts.
