Product Description:

The 16.Z1.F04-1010 is a three-phase sine wave EMC filter manufactured by KEB and supplied within the Z1 Sine Wave EMC Filters series. Installed between an inverter and an induction motor, the unit smooths the pulse-width-modulated output so the connected machine receives a near-sinusoidal voltage, which cuts electromagnetic interference and limits motor insulation stress in industrial automation systems. Its rectangular footprint and assembled height allow placement close to the inverter while helping maintain cable length limits inside a control cabinet.

The filter is sized for drives that draw a continuous current of 33 A from a three-phase bus at 400 VAC. Under these conditions, it supports motors up to 15 kW and transfers fundamental output frequencies between 0 to 100 Hz without resonance. Its core geometry and winding layout are tuned for inverter carrier patterns near 2 kHz, limiting dv/dt so cable stress and acoustic noise stay within common machine-building limits. Using a three-phase topology ensures each line is treated symmetrically, which simplifies harmonic analysis when the drive is feeding standard induction or permanent-magnet machines.

For cabling, the terminals accept conductors up to 10 mm², and the internal windings contain 1.5 kg of copper so thermal rise remains predictable while the filter’s inductance of 0.36 mH provides the required smoothing at the motor end. At rated load, the assembly dissipates 54 W of power, a value that guides enclosure ventilation calculations. Transient line excursions can reach 550 V without damaging the insulation system, giving margin when drives are connected to stiff industrial grids. The complete unit weighs 5.9 kg and occupies a rectangular footprint 178 mm wide by 100 mm deep, while the assembled height is 180 mm.
