Product Description:
The 12.Z1.C04-1000 is a sine-wave electromagnetic compatibility output filter manufactured by KEB for the Z1 Sine Wave EMC Filters series. Positioned between a variable-frequency drive and its motor, the unit converts the high-frequency, pulse-width-modulated signal into a nearly sinusoidal waveform. This reduction in voltage steepness lowers insulation stress, limits bearing currents, and cuts audible noise, making the filter a common component in industrial automation panels where inverter-fed motors run continuously.
Electrical sizing targets medium-power drives. The filter is rated for a line-to-line voltage of 400 V and carries a continuous load current of 10 A. It supports motor systems up to 4 kW while maintaining acceptable conducted emissions. Compatibility with mains frequencies of 50/60 Hz means the same hardware can be deployed worldwide without retuning. For short overloads such as acceleration ramps, the magnetic core withstands 150% for 60 seconds in every ten-minute interval, preventing saturation and excessive temperature rise. Terminals accept 4 mm² conductors, and an M6 protective-earth stud simplifies grounding connections inside the cabinet.
Thermal behavior shows a power dissipation of 110 W, so at least 150 mm of free space should surround the enclosure to facilitate convection. Connection leads may extend up to 5 m between the inverter and motor without degrading the filter’s attenuation curve. The housing carries an IP20 ingress rating, protecting users from live parts while requiring installation in a closed control panel for additional shielding. Overall dimensions are 121 mm high and 219 mm wide, and the assembly weighs 11.5 kg, factors that influence rail loading and cabinet layout. Operation is approved for climatic class 3K3, which suits typical shop-floor control rooms with moderate humidity and temperature.
