Features and benefits
Typical applications
■ Conventional motor drives with long motor
cables and high interference levels
■ Four quadrant motor drives and servo
drives with energy regeneration mode (in
combination with a suitable line reactor)
■ Industrial applications comprising power
conversion devices, such as machinery,
machine tools and process automation
equipment
■ Uninterruptible power supplies (UPS)
■ Converters for alternative energy
generation
■ Thyristor drives
■ Elevators and cranes
■ High-performance filter for mainly
industrial motor drive applications with
significant interference levels.
■ Attenuation performance for Class B com-
pliance in applications comprising multiple
motor drives (e.g. machine tool with up to
8 driving axes with ~10 to 20m motor cable
each).
■ Broadband filter performance with low fre-
quency attenuation down to 10kHz for reli-
able suppression of conducted interference
in applications with regenerative motor
drives.
■ Slim book-style shape requiring minimum
cabinet space and allowing convenient
installation right beside the motor drive.
■ Touch-safe terminal blocks provide unsur-
passed electrical safety and contacting
cross section according to EN 60204-1
installation standard.
■ For even better filter specifications, please
consider FN 3120H series from Schaffner.
