VFD Surge protection products will improve power quality by surge protecting and power filtering the incoming power to the Variable Frequency Drives (VFD). This can be accomplished by installing the TPX-480NN-F surge protector unit at each drive. Or, protect multiple drives by installing a VFD surge protector at drive cabinet or motor control center. For additional surge protection install a small series wired surge protector unit on the circuit feeding the low voltage controls when possible. The VFD surge protector and power filter can be placed at the drive cabinet or individual drive. By being at any of these points you can protect all variable frequency drive VFD equipment from incoming surges/transients from the utility line. In addition the VFD surge protector will protect against all the cross circuit transients generated by the variable frequency drives themselves from switching on and off which damage and degrade equipment overtime in other parts of the facility. Plus, you will clean up transients caused by the drives that can affect electronic loads in other sections of the facility. Surge protection is also recommended to protect VFD equipment when harmonics are an issue.
