Product Description:
The 23.Z1.C04-1000 is an EMC sine wave output filter manufactured by KEB and supplied within the Z1 Sine Wave EMC Filters series. Installed between a PWM drive and the motor, the filter smooths the drive’s pulse train and limits conducted noise on the plant mains, supporting reliable operation of nearby control electronics. By converting the rectangular inverter voltage into an approximate sine form, it reduces motor insulation stress and lengthens cable run possibilities in industrial automation cells.
Designed for three-phase installations running at a rated line of 400 V, the unit can conduct a continuous phase current of 158 A. This current ceiling matches inverter systems feeding motors up to 75 kW, so a single filter stage can cover many medium-power conveyor or fan drives. Compatibility with utility grids operating at 50/60 Hz means no hardware changes are required when a machine is exported across regions. The enclosure carries a IP20 protection rating, limiting ingress to fingers and protecting active parts in ventilated cabinets. The climatic category 3K3 indicates the filter is intended for switch-room environments with controlled temperature and humidity rather than outdoor mounting.
Thermal efficiency is governed by a total power dissipation of 785 W; adequate cabinet airflow must therefore be planned to keep the choke stack within its permissible rise. High-capacity terminals accept conductors up to 95 mm², and a dedicated protective-earth stud uses an M10 bolt to ensure low-impedance grounding. Even with these heavy connections the assembly weight is 162.0 kg, so lifting lugs or rails are recommended during installation. Together these mechanical figures complement the electrical limits outlined earlier, defining cooling, cabling, and handling requirements for reliable filter integration.
