Product Description:

The 16.Z1.C04-1000 sine wave EMC filter is produced by KEB within the Z1 Sine Wave EMC Filters series. As an output filter for AC drives, it reshapes the pulse-width-modulated voltage from an inverter into a near-sinusoidal waveform before it reaches the motor. By smoothing edges and limiting common-mode noise, the unit helps protect motor insulation and reduces electromagnetic interference in industrial automation lines that run three-phase variable-frequency drives.

Electrically, the filter is optimized for drive systems that operate on a rated line voltage of 400 VAC and a continuous current of 34.7 A. These ratings mean the component can be placed between an inverter delivering up to 15 kW of output power and a motor without reaching thermal limits. A maximum permissible line potential of 440 V offers headroom for transients on a three-phase grid, while compatibility with the standard 50 Hz line frequency simplifies use. The internal bus bars accept cables up to 16 mm², and the three-phase topology is arranged so that each coil shares the same magnetic path. With a protection category of IP20, the filter must be installed inside a control cabinet where accidental contact and conductive dust are already managed.

Thermal behavior is dictated by a power dissipation of 260 W, so cabinet ventilation should be sized accordingly to keep the core below its design temperature. The steel enclosure measures 352 mm wide and 145 mm high, allowing placement on a standard DIN backplate without exceeding common panel depths. Overall mass reaches 38.5 kg, of which the copper windings account for 15 kg; this weight contributes to heat capacity and overload tolerance. When installed behind the inverter, the filter keeps harmonic current distortion below 8% and limits partial weighted harmonic distortion to less than 15%, protecting motors from additional losses and audible noise.
