Product Description

220V 380V Sine Wave Filter For Solar VFD Variable Freqyency Inverter


ZK SK SERIES Sine Wave Filter For Solar VFD, Frequency Inverter


Quick details


The filter is a filter circuit composed of capacitance, inductance and resistance. The filter can effectively filter the frequency point of a specific frequency in the power line or the frequency other than the frequency point to obtain a power signal of a specific frequency, or eliminate the power signal of a specific frequency.


Application: it is specially used at the output end of frequency inverter / server to solve the interference of frequency inverter to motor; Reduce motor noise and solve the problem of rapid aging of motor.



1. Specified design for VVVF or servo output side to reduce the EMC interference on motor
2. Prevent the harmonic coming from inverter to interfere the motor
3. Suppression the DV/DT, reloeve the harm of peak voltage from inverterds on the motor, reduce the noise of motor, Prevent the motor from quickly ageing.
4. To reduce the RFI interference from the long cable of frequency inverters on the output side
5. Over-voltage protection,reduce the electromagnetic interference of inverter.
6. Wide working current range from 5A to 1200A.
7. High quality components ensure the safety and reliability of filters.
8. As output filter for inverter,reduce the loss of inverter and motor choke.
9. Various connection optional:bolt and busbar terminala.
