FST Series Input Output Filters for VFD
FST series input output filters are passive EMC filters designed for VFDs and servo drives. These harmonic filters (5A-1600A, 220V/380V/440V) effectively suppress conducted interference along power lines and reduce EMI (electromagnetic interference) generated by inverters. The FST input filters protect the VFD from grid-side disturbances, while FSTL output filters protect motors from dv/dt stress and eliminate whistling in long cable applications. With three-stage filtering design and special magnetic materials, they ensure high impedance across a wide frequency range without requiring fans.

Features
- Rated current 5A-1600A optional
- Bolt and terminal block lead out methods are optional (copper bar lead out method for 300A and above)
- The FSTL series is specially designed based on the frequency domain characteristics of the output end interfering with the load during the operation of the frequency converter
- Effectively solve the abnormal conditions such as load heating and whistling that are easily generated during long- distance transmission of frequency conversion devices, and use them in conjunction with reactors for better results
- For special customer groups, selecting terminal board products can ensure the safety of their products in special situations
- Above 300A, copper bar type lead out method is adopted, which is more consistent with international design standards, making customer connections convenient and safe
- The normal operation of electronic equipment that can effectively ensure the turnover of frequency converters and solve the problem of significant interference from frequency converters
- Adopting a three-level filtering design, special magnetic materials can ensure high impedance characteristics over a wide frequency range
- 660VAC/690VAC/1140VAC (included) and above high working voltage products are optional
