Features and benefits
High performance filter for mainly industrial motor
drive applications with significant interference levels
Attenuation performance for Class B compliance in
applications comprising multiple motor drives (e.g.
machine tool with up to 8 driving axes with ~10 to
20 m motor cable each)
Broadband filter performance with low frequency
attenuation down to 10 kHz for reliable suppression
of conducted interference
Slim book-style shape requiring minimum cabinet
space and allowing convenient installation right
beside the motor drive
Touch-safe terminal blocks provide unsurpassed
electrical safety and contacting cross section
according to EN 60204-1 installation standard
